Relatively often I see in classrooms and people's houses terribly buzzing from cooling fans
stationary workstations (PC).
It turned out that most often the Q-Fan Control parameter is not set in the BIOS at all ...
;--)).... That is, they have it Disabled ;-)
Let's look at other causes of noise ...
What else can be...
1) An increase in fan speed, due to the noise from its operation, may be overheating of system components, especially it concerns laptops . Then you definitely need measure the temperature of a laptop or computer And clean laptop or computer .
2) The old cooler is poorly lubricated, then it needs to be lubricated, we wrote about this:
How to lubricate the fan or extend the fan's "life" or How to lubricate a cooler bearing.
3) A new proprietary cooler is selected with a higher number of revolutions than necessary.
Exit from this situation is simple - reduce cooler speed.
So, we have found out that by reducing the number of revolutions of the cooler, we will reduce the noise that it produces.
Of course, productivity will drop a little, but let's say that in some "nodes" of the computer this will not give a significant deterioration in cooling. So, fans that are installed in cases and power supplies are high-board, and the ratio is not always noise/performance be at the optimum level.
There are several ways in which you can reduce noise, and the cooling remains at an acceptable level.
So to speak, find the golden mean in relation to noise/performance.
Let's start with the simplest and cheapest ways:
Method number 1.
Enabling a function in the BIOS that regulates the fan speed automatically.
On principle than more load to the computer, the faster the fans spin.
This feature is enabled by default in all laptops (to extend battery life) and if the fan does not automatically reduce speed in idle, then this is a serious signal about laptop overheating .
Also, this feature is supported by some motherboards: ASUS(Q-fan control), Abit(Smart fan control), etc.
Let's look at an example motherboard ASUS function Q Fan Control, with presets Silent/Optimal/Performances.
Where to enable Q-Fan in ASUS EFI BIOS, see Setting up Asus EFI BIOS.
1) We go into the BIOS (Immediately before the start of the download, press the button repeatedly)
2) From section Main
go to section power
3) Select a line Hardware Monitor
4) Change the value of the lines CPU Q Fan control And Chassis Q-Fan Control on Enabled
5) As a result, lines will appear CPU
And Chassis Fan Profile
.
In these lines, you can select three modes of operation:
- performances
is the performance mode
- silent
- this is the quietest mode,
- Optimal
- This is an intermediate mode between productive and quiet.
6) Then save the settings via
Important! Automatic fan adjustment will be performed only on the connectors CHA_FAN
And CPU_FAN
.
A PWR_FAN
not controlled by Q-Fan Control.
Similar adjustment systems are also present on other motherboards from other manufacturers.
If your board does not support this function, then I recommend paying attention to other methods.
Method number 2. Decreasing cooler speed by switching.
In order to reduce the fan speed, you can switch the fan to a lower voltage.
The nominal voltage for the fan is 12 volts. And the entire specification (speed, noise level, current consumption, etc.) is indicated for the rated voltage.
We can switch our fan to three other voltage ratings: +12 Volts, +7 Volts, +5 Volts.
This is done using the usual Molex connector, which is present in sufficient quantities in all modern power supplies.
In order to switch the case fan you need:
1) Turn off the computer, open the lid and disconnect the desired fan from the socket to which it is connected.
2) Release the desired legs, using a needle or an awl, from the 3-pin fan connector.
3) Just bite off the wires of the power supply fan at the board itself (usually two red wires are "plus" and black are "minus"), bring the power supply outside, and also connect to a free molex connector.
4) And connect it to the Molex connector for the voltage you need:
At 12 volts:
At 7 volts:
At 5 volts:
Approximately these speeds will be at the nominal voltage values of the fan from 2000 rpm and 3500 rpm:
Important! Never change the pins on the Molex connector itself.
This may damage the equipment.
More than once I witnessed how a hard drive was connected to a Molex connector, in which the legs were rearranged not according to the standard. The result - the hard drive is out of order irrevocably!!!
Method number 3. Fan speed control with reobas.
To be able to constantly adjust the fan, you can use a device called REOBAS.
Reobas is a device that allows you to smoothly adjust the voltage that is supplied to the fan. As a result, the speed of the fan is smoothly regulated.
Reobas can be made by yourself using the scheme below:
The first circuit is similar to the regulator fanmate from Zalman, which is used on CPU coolers.
Good day, dear friends, readers, visitors and other personalities. Let's talk about the program today. speedfan which is clear from the title.
I think that you all remember the article "", which told you a lot of all sorts useful information about heating the contents of your iron friend and a few words about how to deal with this heating, namely, for example, by or.
But what if everything is more than normal with temperatures, and the computer is buzzing like damn? The answer is simple: you need to somehow regulate the speed of the fans, because they are the cause of noise in most cases. Just how to do this will be discussed in this article.
Introduction about computer cooler speed
Let's start with how the adjustment, if any, occurs at all.
Initially, the rotation speed is determined and set based on the temperature readings and the settings specified in .
The motherboard, in turn, does this by changing the voltage / resistance and other nuances, smartly controlling the number of revolutions (RPM), based on the settings you specified, as well as the temperature of the computer components as such and inside the case in general.
However, far from always, despite all the smart adjustment technologies (Q-Fan and others like them), it clearly does its job, and therefore the knobs either work too hard (often this is exactly what happens), which creates a non-illusory noise, or too little (rare), which raises the temperature.
How to be? There are at least three options:
- Try to configure everything in the BIOS;
- Take advantage of specialized programs;
- Or physically pick something with power (or by buying all sorts of reobass and other physical devices).
The BIOS option is far from always justified, because, firstly, such technology is not available everywhere, secondly, it is far from being as intelligent as it seems, and, thirdly, it may be necessary to change everything manually and on the fly.
Additional information on speed
Again, not all of them are plugged into the motherboard (this is especially true in the case of chassis ones), i.e. the BIOS does not know about their existence, and therefore cannot control them, i.e. they spin at full power, often idle and, again, increasing the overall noise level (for more on this, that is, on connection, see below).
The option with a physical solution is quite .. Cruel, because cutting the wires is inhumane, and this is more likely not a method of adjustment, but a forced reduction in performance, because, again, you can’t adjust according to your needs - picking the wires every time you are tormented.
You can, of course, buy a reobas (as in the one below), to which you can connect everything and enjoy life, but this, again, costs money, and it can be lazy to reach for the case whenever you need to change the rotation speed.
Therefore, in connection with the foregoing, for many, the option of using specialized programs will be relevant, since they are available and they are free. In this article, I will talk about an old and very famous utility called SpeedFan.
How to increase or decrease the fan speed in a SpeedFan computer
You can download SpeedFan. Of course, the program is completely free, however, it does not support the Russian language, but it does not matter because, in general, everything is clear;)
Installation is extremely simple and I will not dwell on it, and therefore I will go straight to use.
At the first start, this window may come out:
Feel free to check the box " Do not show again" and click on the button " Close".
Let's see what's what, as in more new version SpeedFan program (it is in the screenshot above), and the older one (in the screenshot below). They differ slightly in value labels, but the principle of operation is similar:
The "Cpu Usage" field and the indicators next to it show the current load and its. The "Minimize" and "Configure" buttons allow you to minimize the program, or open its settings.
The "Automatic fan speed" checkbox enables automatic fan speed control. You can use it, but there is no point, as such, in general, otherwise why did you install this program at all, if everything suited you as it is?
IMPORTANT ! The list of indicators does not necessarily refer to this or that cooler, as it is signed in the program! That is, if it is CPU or Fan1, it does not mean that this is the speed of the processor cooler, because it all depends on which slot the fan is connected to by the assembler (or you) directly on the motherboard and how correctly the program reads data about this socket! Ideally, determine the speed by changing the value and looking into the open case.
Details on various controllers in SpeedFan
I tell you what is what in the case of the rotation speed indicator (measured in RPM, i.e. in the number of revolutions per minute):
- SysFan (Fan1), - shows the rotation speed of the spinner (I mean the fan) connected to the SysFan socket on the motherboard. It can be either a cooler installed on the chipset, or any other cooler simply plugged into this connector (all connectors on the motherboard are labeled accordingly);
- CPU0 Fan (Fan2), - shows the rotation speed of the knob on the processor, i.e. the fan plugged into the CPU_Fan connector on the motherboard;
- Aux0 Fan (Fan3), - talks about the current fan speed connected to the AUX0 connector;
- CPU1 Fan (Fan4) , - similar to CPU0 , but only if you have a second processor or cooler slot labeled CPU1_Fan;
- Aux1 Fan (Fan5), - similar to Aux0, i.e. shows the rotation speed for the cooler plugged into the AUX1_Fan connector;
- PWR Fan (Fan6), - it happens that the rotation speed of the cooler installed (not always) is indicated here, or simply the speed of the fan that is plugged into the PWR_Fan connector on the board.
Once again, I note that each parameter here corresponds to motherboard connector and almost any cooler can be plugged into any of them, and then its indicator will be displayed in the corresponding column.
Naturally, this should be plugged into the motherboard through a small 3-pin connector, and not powered from the power supply. To make it clear, let's show you a photo.
Cooler connectors and their photos
The correct connector and the correct socket (the socket in the picture is 4-pin, and the connector is 3-pin) so that you can watch and adjust the rotation speed:
The "wrong" connector, i.e. power supply from the power supply, which does not allow (see note above) to monitor and, often, change the rotation speed using the program, BIOS, and anything else:
Tobish, if, during assembly, some of your coolers (for example, case coolers) are powered from the power supply unit by the above connector, then I recommend getting into the computer and plugging them into the motherboard so that you can steer the fans as you like.
To the right of the above values, as I said, temperatures are indicated. For me personally, they are not filmed accurately and adequately enough, and therefore I recommend using analogues like or and drawing conclusions based on them.
And now the most delicious. Below, opposite each inscription Speed01-06 (or in later versions of the program it can be Pwm1-3 , Pwm1-3 ), there are arrows, by clicking on which we can adjust the rotation speed of a particular fan. In fact, they are what we need. Try playing with them by moving them up and down and you will see how much quieter / louder your computer can work.
By the way, to understand which column regulates the speed of which cooler, just watch the change in RPM values. Naturally, it is not recommended to turn off the fans completely, so as not to burn something and, of course, that it is necessary to simultaneously look at the temperatures when adjusting the values.
Disable/Enable Auto Speed Control in BIOS
Depending on the type of motherboard, the version and type of its BIOS, and other factors, the program may not work if the BIOS has enabled or disabled adjustment automatically or based on specified templates.
Therefore, it is possible that if you encounter problems in the operation of the program and it works (or does not work), or if you want to entrust the control of the motherboard, then you may need to enable or disable the adjustment system built into the BIOS. Approximately, depending on the version, this is done like this:
That is, Q-Fan in the Enable position enables automatic control based on the settings in the BIOS, and Disable disables this option. Depending on the BIOS type, as you can see in the screenshots above, this option can be located on different tabs and look different. It is also possible that you need to switch CPU Fan Profile from Auto to Manual or vice versa.
Unfortunately, it is impossible to consider all variations, but one way or another, this tab is always present on any computer (with the exception, perhaps, of laptops) and you can find it there. In particular, it is not always called Q-Fan , it can be something like CPU Fan Control , Fan Monitor and similar.
In a nutshell, something like this. Let's move on to the afterword.
Afterword
Something like this. About all sorts of deep settings and other tabs, within the framework of this article, I will not talk, since they are not particularly needed. The remaining tabs are responsible for overclocking, information and other useful data (more on that later).
As part of the next article from this series, I told in detail how to adjust the speed, because they have their own BIOS and fan, powered not from the motherboard or PSU, but from the card itself, and therefore it will not work to control them through SpeedFan or motherboard.
As always, if you have any questions, thoughts, additions, comments, and so on, then welcome to comment on this post.
Good evening everyone. Another article is on the way. Today the topic will touch on the physical side of the computer, namely the noise of the fans. While working in technical support, I noticed that a lot of users are asking to reduce the noise from their computer. First, find out the cause of this increased noise. It is possible that the computer simply has not been cleaned and lubricated for a long time. But there is a second version of this reason - they flew off / changed / reset the settings in the BIOS. Regarding the first part, it is not difficult to take a vacuum cleaner and a rag and remove all the dirt and dust. Regarding the second case, some BIOS orientation skills are required. Right now, I'm going to tell you about it.
We reduce the noise of the computer through the BIOS.
So we made sure that the computer is clean and the fans are working. Now we turn on the computer and by pressing the special keys, we get into the BIOS setup menu. You can find out which button to press by the start picture, or by enumeration. Most often this following buttons: Del, F2 and F10.
In my case, I got maternal ASUS board, which has a BIOS entry button - Del.
Immediately we get to the main tab -Main, there is nothing valuable for us here, so we move to Power with the left arrow.
Having stopped on this tab, we begin to walk through the points and select "Hardware Monitor".
A page will open where there will be a whole list of various add-ons. Yes, and it is also possible that the CPU Q-Fan Control item will contain the inscription Disabled, we can change this by going to it with the down arrow and pressing Enter.
Well, accordingly, now it will open full list possible settings. Here are presented both the settings for the processor fan and the case fans, by the way, case fans are indicated by the word chassis.
Among all presented, a very important point for us is the CPU Fan Profile. The same profile with settings that determines maximum amount fan revolutions per minute.
Again, if you click on this item, a list (in my case) of three items will appear. The default was chosen - Optimal.
In short, then:
Optimal- this is an intermediate mode between productive and quiet;
silent- this is the quietest mode;
Performance is the performance mode
We opt for Silent. Then we press the F10 button and the BIOS will prompt us to save the changes, we agree and the computer will reboot itself.
Already when turned on, the fans will first “buzz” strongly, and then reduce the speed to work in quiet mode. If the noise still remains, then there are two reasons:
- There are two types of fan headers on the motherboard. Some are signed as "CHA_FAN" and "CPU_FAN", the second is simply "PWR_FAN". So, only the first ones are controllable, while the second type is simply feeding;
- Conventional fans (with two or three pins) are connected, such fans are not controlled. Managed have a connector of 4 legs.
Conclusion.
After completing all the proposed instructions, we get a computer with a quiet mode of operation. Now you are calm and your colleagues do not complain. Good luck!
Today we will look at:
The temperature of all components is a very important factor if you want your computer or laptop to work properly for a long time. Fans can be controlled different ways, one of which is adjusting the cooler in the BIOS.
In this topic, we will talk about how to configure fans in a computer through BIOS and what opportunities this shell provides for this.
Foreword
Why would you need manual fan control? First of all, this is what we said in the introduction: setting up an optimal cooling system for a PC. However, in addition to this, performing these actions can be useful if you need to, say, reduce the amount of noise emitted by coolers.
Talk about a variety of downloadable utilities or built-in Windows tools we will not. We will leave this material for later topics. Today we will only touch upon the BIOS's ability to adjust coolers. We will consider this topic using the American Megatrends BIOS as an example. In other versions of this shell, this procedure is performed in a similar way.
Cooler management
Adjusting the cooler in BIOS is extremely easy. First of all, you need to enter the BIOS itself. On our site you can find many topics where we talked about BIOS and how to enter this shell on different devices.
While in the BIOS (in our case, in the AMI BIOS), go to the "Power" category. In other versions, this tab may be called "Hardware Monitor".
On this page you will see information about the operation of the processor fan, and you can also configure its operation.
In addition to the fact that here you can view the current temperature CPU and motherboard, you can also see the current fan speed (RPM) and the voltage the fans are receiving.
The cooler is adjusted in BIOS through the “CPU Fan Profile” item, in which, as a rule, 3 modes are available:
- turbo - maximum energy consumption and maximum number of revolutions;
- standard - optimal mode;
- Quiet – fan setting for maximum silent operation.
After selecting the mode, exit the BIOS after saving all changes made. The next time you start your PC, you will see that the coolers have started to work in accordance with the specified mode.
Outcome
As you can see, setting up a cooling system in a computer through BIOS is a very simple and accessible process for everyone. If you follow the instructions described above and do not change other parameters, then in this way you will protect your computer from breakdowns, and the temperature of the working parts will be at an acceptable level. Write in the comments under this article how you regulate the cooling system inside system block and what tools do you use for this purpose.
It is no secret that with the increase in the speed of computers, the level of heat generated by the system components also increases: the chipset of the motherboard heats up, the central processor heats up seriously (at high load, the temperature of the processor core can reach 90-110 ° C), does not lag behind the central one in terms of heat dissipation and GPU video cards and even power supplies with an increase in power began to heat up very much. Therefore, increasingly powerful and large cooling fans are required for all components, which can be very noisy. However, some of the problems associated with increased system noise can be solved by software and even BIOS settings. For example, modern processors and OS automatically reduce power consumption during idle periods to help keep devices cool, but they rarely slow down noisy fans.
Smart Fan Control
Most modern computers The fans can be controlled via the Basic Input/Output System (BIOS). The easiest way is to change the settings in the BIOS to turn the fans on and off depending on the temperature (if, of course, there is such a possibility).
Some BIOS systems have in the menu (PC Health Status section) some kind of function such as Smart CPU Fan Temperature, CPU Smart Fan Control, or even Noise Control. It is enough to enable this function, and the noise from the fans will bother you only at the time of loading (usually, regardless of the temperature set in Smart Fan Control, the processor fan runs at full power for several seconds when the computer is turned on, and then slows down) or at those rare moments when you really load the computer with some complex operations.
After enabling this option during operation, the processor fan will increase speed only when the temperature rises, and if there is no load, it will decrease (the fan may even turn off altogether).
Note that the function of smooth automatic fan speed control Smart Fan Control usually works reliably only on those fans that are equipped with a fourth control wire. In addition, the presence of CPU Smart Fan Control sometimes depends on the installed processor. By the way, this function is usually not enabled by default, so in any case you will have to configure it manually (configuration is usually limited to enabling this function and / or setting critical temperatures).
Of course, reducing the speed of the fans will inevitably lead to an increase in the temperature inside the system unit, but so far the processor, HDD and other components are operating within the allowed temperature range (check with your hardware vendor), the hardware is not in danger. Safe operating temperatures are roughly around 70°C for processors and 55°C for hard drives. The maximum allowable operating temperature for Intel processors can be found on the company's website (for example, for Pentium 4 processors - http://www.intel.com/support/processors/pentium4/sb/CS-007999.htm). For AMD processors you can check the value of the Case Temp parameter on the Technical Documents Page(). Recall that for a particular processor, stable operation temperatures may vary. The maximum temperature for hard drive can be found on the respective supplier's website.
Noise reduction technologies in Intel Core 2 Duo
Intel's new multi-core processors (including the Core 2 Duo) have relatively low power consumption and, as a result, generate less heat. This feature can be used in different ways: either to overclock the system, or, conversely, to reduce the noise from the cooling system.
BIOS setup in motherboards for Core 2 Duo (for example, on the i975X chipset) is not difficult - it consists in activating such additional features, such as Intel SpeedStep (reducing power consumption during processor idle), and AI Quiet technology (intelligent fan control to reduce noise).
In silent mode (Silent mode) in a computer with a conventional cooling system, even after several hours, the temperature of the processor does not rise above 35-40 ° C, and in a system with passive cooling, the processor heats up to 50-55 ° C. The temperature of hard drives rarely exceeds 40-45°C, and the temperature in the case is set at 35-40°C. These are very good results for modern computers, given that in a truly silent mode, the air circulation in the case is very weak.
AMD Cool'n'Quiet Technology
AMD's Cool'n'Quiet technology is Intel's answer to old problems with heat and noise generated by the cooling system. New technology, designed to reduce power consumption and, accordingly, reduce the level of noise produced by the cooling system, has found its application in all modern chipsets for motherboards designed for AMD processors. The processor fan and other cooling fans connected to the motherboard will only increase speed when the temperature rises, and if there is no load, they may turn off altogether.
Recall that AMD platforms are usually also equipped with D.O.T. (Dynamic Overclocking Technology) with the most automated overclocking of 10%.
We also note that each manufacturer of chipsets and motherboards for a particular platform introduces its own additional technologies to support similar decisions to reduce noise from computers.
MSI's multifunctional CoreCell technology
AMD's strategic partner, motherboard manufacturer MSI, has developed its own features to support the AMD Cool'n'Quiet solution.
MSI's motherboard adopts the original multifunctional CoreCell technology. The CoreCell Chip includes four components: Speedster (a technology that allows flexible BIOS settings), BuzzFree (a technology that reduces system noise by automatically adjusting fan speeds), PowerPro (a power management technology that can reduce power consumption), and LifePro (a technology that maximizes prolonging the life of the motherboard, processor and cooling fans by constantly monitoring their condition).
Speedster technology provides the user with the ability to flexibly adjust BIOS settings during overclocking, including asynchronous bus (FSB) and memory speed modes, the ability to increase the voltage supplied to the memory in 0.05 V steps to adjust it, and the voltage supplied to the processor core with with a minimum step of 0.0125 V.
BuzzFree technology is designed to check the current load of the system, its temperature and change the speed of rotation of the cooling fans in accordance with the state of the system. Thanks to BuzzFree, the level of noise produced by the system is significantly reduced (by 10-50%), and annoying buzzing of fans practically does not bother users. We also note that BuzzFree improves the playback quality of audio and video files. This technology coordinated with AMD Cool'n'Quiet technology.
PowerPro technology extends the life of your motherboard and fans by keeping them in optimal condition. This system also monitors the load on the motherboard in order to avoid negative factors that could lead to a system crash.
PowerPro is a flexible system power management that reduces power consumption by up to 67%, ensures stability and increases performance.
LifePro technology also increases system reliability by maintaining the most favorable state of the system as a whole and by component. LifePro monitors all operations to prevent system failure and extend the life of the motherboard, CPU, and other components.
For platform AMD Dual Core, MSI has implemented Dual CoreCell, a feature rich technology similar to CoreCell but for dual-core AM2 motherboards.
MSI Dual Core Cell is software development MSI, which provides hardware monitoring, overclocking and cooling system management.
Compared with CoreCell technology, Dual CoreCell is focused not only on improving performance, but also on improving the user experience of the system. It includes four sections: performance level, noise level, and image and sound quality, providing the user with a working environment that satisfies him.
SilentTek - noise reduction technology from AOpen
Almost all motherboard manufacturers are engaged in developments in the field of noise reduction. For example, AOpen, in addition to increasing the performance and functional stuffing of motherboards, pays a lot of attention to the ergonomics of its devices, even if these are cheap solutions. To reduce the noise level from a running computer, special tools are used that allow you to adjust the fan speed depending on temperature regime and limit top speed rotate the optical drive so that it also produces less noise.
The original development of AOpen engineers is called SilentTek - this function is built into the BIOS and also has a special proprietary management utility for Windows.
SilentTek manages features such as Hardware-Status Monitoring (monitoring system status), Overheat Warning (warning about overheating) and Fan Speed Control (fan speed control). With SilentTek, you can achieve the optimal balance between noise, performance and system stability.
When using a computer at home, SilentBIOS technology built into the BIOS can be an invaluable advantage, as well as support for software control of the speed of rotation of all fans, which allows minimizing system noise directly during operation.
The SilentTek proprietary utility from AOpen allows you to monitor the operation parameters of various PC components (voltages, temperatures, etc.) in real time, and also has a set of special features with which you can select best ratio between noise (fan speeds) and cooling of the motherboard, processor and power supply.
Instead of a conclusion
We did not find any shortcomings in the operation of these systems, however, it should be borne in mind that these technologies are still relatively new and therefore may well have some roughness in operation until the BIOS versions that support them are fully debugged.
But even if there is no such function in the BIOS (or it is not open in the settings menu), then you can achieve relative silence using some special program. For example, one might note free program SpeedFan (http://www.almico.com/speedfan.php), which has a large database of modern motherboards, reads temperature sensors and then changes the fan speed based on temperature readings (SpeedFan program can be found on our CD-ROM ).
However, for such a program to work, the following conditions must be met: the readings of the hardware temperature sensors must be readable by the program (that is, the program must “know” your motherboard), the computer hardware must provide a change in the fan speed, and, finally, the user will have to configure program and monitor the progress of its work (at least find out the safe temperature range at which certain computer components will not fail).
