Program for automatic control of a cpu cooler. Adjusting the cooler rotation speed

Do you want to find out how seriously the system unit heats up (this is especially important in the summer) and reduce the noise of a computer that seems to be about to take off. Then you need to get into the BIOS, trying to wait for the necessary settings, unless of course you are afraid to change something like that, but this is only suitable for advanced users or everyone else is trying to make do with the utilities that come on the disks with motherboards, which theoretically allows you to control the operation of the fans, although usually quite ineffective. As always, there is a third way - utilities from third-party developers who can work with most modern hardware. One of the popular utilities that allows you to take data from the sensors of the motherboard, video card, power supply and hard drives, as well as control the operation of fans, is SpeedFan.

Installation of the utility proceeds according to the standard scenario, confirmation of the license agreement, dates of approval for placing icons to launch the utility, select the folder where the files will be located. Well, that’s all, the program is completely ready to work.

SpeedFan collects all kinds of data about your computer, such as temperature, voltage, processor frequency and cooler rotation speed, and theoretically (you will find out why later) allows you to regulate the operation of fans and change the processor frequency.

The utility's interface looks unprepossessing, but it is simple and clear, where all the features are grouped into separate tabs, although some of them have very strange names:

- Indicators. Here we are given all the information about temperature, fan speed and voltage, but most importantly, this is where we limit the fan rotation speed. We limit the revolutions by changing the numbers in the paragraphs signed Pwm* (from previous versions they were called Speed*), setting how many percent it will work from maximum speed cooler.

Frequencies. Here you can change the frequency of the processor and system buses, but I do not recommend turning or turning on anything here for ordinary users who are far from computers. If anyone is interested, first select the manufacturer of the motherboard, then the clock frequency generator that is used (it’s better not to select anything at random), only then we set what frequency the processor will operate at depending on the load on the system.

Information. There is nothing interesting here for ordinary users. In fact, they offer to read data about the chipset used on motherboard and send utilities to developers so that they can implement support for common hardware and sensors.

Exotic. Hidden under such a strange name is a sign that displays all the parameters that the utility monitors, illustrating with arrows which values ​​are falling or rising.

- S.M.A.R.T. here we can find out about the status of the hard drives, where green circles mean that everything is fine. If you see a yellow triangle, then the hard drive is in a pre-emergency state, and a red circle means that some of the parameters have gone beyond critical values, and data loss is only a matter of time. Select the desired hard drive from the top drop-down list.

Charts. In this section, those interested can familiarize themselves with the statistics of changes in temperature, fan speed and voltage in the form of graphs.

Now about some features of SpeedFan. To begin with, the utility does not always correctly determine temperatures, so for an experiment you can first try alternative utilities and compare the results and make settings. Also, in order for the fan speed to be adjusted, they must be connected to the motherboard in a 3-pin connector. Although, again, not every motherboard allows you to adjust the fan speed.

The names of the fans look very sad, they only differ in digital indices and it is not clear which one is responsible for what. Although it all depends on the motherboard, some parts of the coolers have meaningful names. We have to use cunning experiments to get to the bottom of how to stop with crayfish, race in games and just watch how the speed changes after changing the parameters.

The settings can be accessed from the “Indicators” tab by clicking on the “Configuration” button and a lot of interesting things are hidden here that will allow you to customize SpeedFan for yourself. Here you can disable unused or duplicate sensors and fans, configure the optimal and critical temperature for each sensor (for example, I had to raise it to 85 degrees for the video card), enable automatic adjustment of the fans, depending on the temperature of the sensors. For dessert, those who wish can write scripts that will be executed upon certain events, launching programs, sending letters to email or causing pop-up warning windows.

SpeedFan basically works by giving out a bunch of useful and not so useful information, allowing you to adjust the fan speed. But getting it to work correctly is a whole art, where you first have to experiment with understanding the terms and surf the forums. Although, as the simplest option that does not require much effort, you can reduce the numbers in Pwm* on the main tab.

If your computer is very noisy, your hands are straight and you are willing to spend a little free time, then you should install and configure SpeedFan correctly.

Works great in 32 and 64 bit operating system. The program interface has been translated into several dozen languages, including Russian, although some phrases remain in English.

For temperature monitoring of the main components of the computer and for adjusting the rotation speed of the processor cooler and other fans installed in the computer. But before you start using the program, you need to install the Russian language in the program and make settings for the program.

How to change language in SpeedFan

First you need to configure the interface in SpeedFan and make it in Russian, and to do this, launch the program and close additional window called Hint by clicking on the Close button. Then in the program window you need to click on the Configure button.

Program for increasing the speed of the SpeedFan cooler with an English interface

A window called Configure will open. In this window, you need to go to the Options tab.

SpeedFan crack on the Options tab

On this tab, in the Language item, you need to select Russian from the pop-up list and click on the OK button located at the bottom of the program window. After this, the window called Configure will close, and the program interface will already be displayed in Russian.

How to set up the SpeedFan program

Now you need to configure SpeedFan correctly, and to do this, open the Configuration window again and go to the Options tab.

Recommended program settings

On this tab, you can check the boxes Run minimized and Minimize when closing, so that when you start and close the program, it will immediately minimize and hide in the tray. You can also check the box next to Full fan speed on exit, since when you restart the computer, more energy is consumed and the computer heats up more. If you check the static icon box, then just the program icon will be displayed in the tray instead of the temperature readings from the sensors. By clicking on the OK button, all settings will be applied.

In SpeedFan how to change the fan speed

With this program you can set the fan speed in automatic or manual mode. In order for the program for adjusting the cooler speed to work in automatic mode, you must first set the minimum and maximum temperature conditions at which the fans will spin slowly or at full power.

SpeedFan fan speed setting

Open the Configuration window and on the Speeds tab you will see how many fans and on which devices this program can regulate the fan speed. On this tab, click on the desired fan and at the bottom of the window, check the Auto Change box. Do this with those fans that you want to regulate.

Setting temperature conditions for fan operation

Then we go to the Temperature tab and see that there are many sensors indicating temperature, but not all devices have fans installed. On this tab, click on the device for which you set Autochange on the Speed ​​tab and at the bottom of the window set the temperature limits in the Desired and Alarm items. If the temperature is below the set Desired, the fans will spin slowly, and if the temperature is higher than the set Alarm, the fans will start spinning at full speed. Thus, set the temperature conditions for all the fans that you want to regulate, and when everything is ready, click OK and the configuration window will close.

In SpeedFan temperature controller fan speed operates in automatic mode

For the specified parameters to start working, you need to check the box next to Auto fan speed in the program window.

Video

In this video called SpeedFan how to use the video explains how to change the rotation speed of the cooler depending on the temperature.

Is your computer making a lot of noise? This is the fans working. There can be from 2 to 5 of them in a computer! And you can’t live without them either. They cool the radiators, and the latter, in turn, cool the microcircuits, as well as the chipset, hard drive etc. Some fans are quiet, some are very noisy. There is a free program SpeedFan, which reads all data from temperature sensors in the computer system unit (temperature of the chipset, processor, hard drives etc.), and then independently regulates the speed of the cooling fans, thereby reducing noise.

During operation, equipment heats up, especially in summer. According to statistics in summer period Computers break down three times more often! Due to increased air temperature and humidity, the central processor, power supplies and other computer components overheat. It is necessary to monitor the temperature inside the “system unit” and regulate it in time.

With monitoring, everything is more or less simple. There are many different programs for this purpose. But not everyone can regulate the temperature.

Free computer program “BOOKMARKS”

Description: A small free program is installed on your computer and is designed to remind you of events, you can turn on any programs at a certain time.

It is possible to enable autoloading with a memory function. For example, when you turn on the computer at a specified time, the Bookmarks program will remind you of a recorded event or, for example, will turn on some program that you had previously specified.

There are two main reasons for overclocking the fan. The first one is too high temperature of components inside system unit, not associated with dust contamination of the computer or malfunction of the cooling systems. In this case it is logical increase speed cooling fans within acceptable limits.

The second reason, on the contrary, requires decrease this same speed - increased noise. It is important to find a reasonable compromise in all this - the quietest possible operation with sufficient cooling of the component elements. Therefore, it is necessary somehow change fan rotation speed. How to do this will be discussed further.

Initially, the speed of revolutions is indicated in the settings B.I.OS, based on which the computer motherboard sets the specified parameters, in particular changing the voltage, supplied to the fans, thus controlling the number rpm. However, this speed can be controlled not at all coolers, but only on three outputs, two-output ones will always work on greatest speed.

You can also adjust the speed of the fans installed on the video adapter and the central processor.

This can be done using BIOS(UEFI) or using third-party programs, and some manufacturers produce their own proprietary utilities for monitoring cooling systems for laptops.

Increase speed through BIOS

In order to initialization During system startup, press Del or F2 (or another option, depending on the BIOS). We find there an option related to the cooler speed, usually this CPU Fan Speed and change the value.

If there is no such item there or it is impossible to make changes, then this can be done using special software.

Some BIOS have options such as Smart CPU Fan Temperature, CPU Smart Fan Control or Noise Control, the inclusion of which will allow you reduce noise when turned on and auto-adjustment rpm during operation, that is, if the load is increased, the rpm increases, otherwise it decreases, until it turns off completely.

That is, setting in this way consists of setting a limiting temperature or simple switching on this function in the BIOS.

Using speedfan

The most popular program for adjusting the rotation speed of coolers is SpeedFan. An old and very famous utility, free and easy to use. Finding and downloading it will not be a problem.

The installation process is shown below. Everything is intuitive.

Having installed program we will see the following window.

The operating principle of all versions is similar.

See CPU load on at the moment maybe in the field CPU Usage. To enable automatic rotation adjustment, check the box. Automatic Fan speed.

Below is a set of speeds and temperatures set for your fans, where:

• RPM– number of revolutions per minute;
• Fan1– cooler connected to the connector near the chipset;
• Fan2– the cooler on the processor is also called CPUFan,
• Fan4 - second CPU fan, if there is one;
• Fan3– a propeller attached to the AUX0 terminals;
• Fan5– AUX1;
• PWRFan– cooler in the power supply;
• GPUFan– video card fan.

Below in percentage you can change range of smallest and largest rpm, adjusting them by pressing the arrows. This will immediately affect the volume of their work, which you will immediately feel. Just do not turn off the fans completely, there is a risk of burning some of the components.

Speed ​​adjustment using AMD OverDrive and Riva Tunes

Proprietary utility AMD OverDrive will allow you to change settings for AMD platforms.

Among many other features, you can also programmatically control rotation speed coolers.

You can run this program only on chipsets supported by AMD 770, 780G, 785G, 790FX/790GX/790X, 890FX/890G//890GX, 970, 990FX/990X, A75, A85X.

After launching the program, click section Fan control and select the necessary characteristics fan speeds.

Another interesting program with the function of regulating the speed of coolers is Riva Tuner. First of all, owners of very hot video cards prefer to use it.

Download and install the program. In our case, this is version 2.21.

Running it, we find low-level system settings, then open the tab Cooler. The following window opens before us.

Tick ​​on Enable Low Level Control cooler Creating a preset fan speed, indicating the desired value as a percentage. Let's create several presets.

Create a task depending on when you want to reduce the fan speed, that is, by adjusting schedule, range temperatures and others characteristics.

This way you can achieve a fine settings cooler speeds depending on changes in temperature of the system unit components.
