Program for overclocking coolers on the computer SpeedFan. Adjusting the speed of work of the coolers

If the cooler (fan) on any PC device does not accelerate to maximum revolutions automatically, which leads to overheating, it makes sense to use the SpeedFan utility. This application allows you to set a constant rotational speed of the screws or adjust its variation depending on the temperature read from the main sensors. The SpeedFan utility works only with those coolers, the speed of which can be adjusted through the BIOS.

Short Description SpeedFan

The program for overclocking the SpeedFan coolers is free. It is suitable for changing the speed of the fans installed on the video card, the CPU, the motherboard chipset. Before installing and running the utility, you must disable automatic adjustment in the BIOS. If this condition is not met, the utility may incorrectly read information about the maximum possible speed of the screws and will not be able to untwist them to the extreme level in a critical situation.

For example, if the BIOS blocks the CPU cooler at 700 RPM during startup, the SpeedFan application will take this value as the maximum. When the CPU temperature rises, the fan for the PC will not overclock. This will lead to forced shutdown of the computer or a breakdown of the CPU.

Installation and first launch

The installation distribution should only be downloaded from the official resource of the software manufacturer. In any case, it is advisable to check the downloaded file for viruses. In general, the installation process is standard. At the first step you will be asked to accept the license agreement. On the second one, you can select places for creating shortcuts. The third one is to set the directory for unpacking the utility files.

During the first run, the program for overclocking the coolers will search for all available temperature sensors and fans. When this process is completed, a window with a little help will appear on the screen. If you do not want it to appear after every program start, tick the checkbox and click on "Close".

When the help window is closed, you will see the main application tab. Initially, the program installed English localization. To switch the interface language, follow these steps:

1. Click on "Configure" in the upper left part of the main window.

2. Click the "Options" tab.

3. In the "Language" menu, select the desired language. Russian localization is already built into the utility.

Main Window

The blocks of the main window show basic information. On the right is information about the temperature of the main components of the computer, such as a graphics processor, a video card, a chipset, a central processor, a hard disk. In addition to real, the program for overclocking coolers will show here and "garbage". To determine the indicators that you should not pay attention to, you need to use the AIDA64 utility. To do this, compare the indicators in SpeedFan and AIDA64. If there are no values in the latter, then it is not necessary to take them into account.

On the left is a list of cooler controllers. The list usually displays more fans than is installed on the computer. Some of them display the speed of real coolers. Others, like in the case of temperature data, contain "garbage". Invalid data in blocks is the only minus of the utility that goes into each new edition.

Determination of the correspondences between sensors and coolers

At the bottom of the program are the speed control screws. Their names are "Speed01", "Speed02", etc. (in SpeedFan in Russian - "Fan1", "Fan2"). But before adjusting the speed, you first need to determine the correspondence between the regulators and the coolers.

The easiest way to do this is on a desktop computer. Remove the left cover of the system unit. Change the value of the first regulator by several tens of percent. Observe which cooler has started spinning - more intensively or more slowly. Also write down or remember the line in the left block where the value has changed.

Users of laptops are most easily identified by using the AIDA64 utility. At the same time, AIDA64 and the program for overclocking the SpeedFan coolers should be started. After changing the value of one of the controls in the SpeedFan, follow in AIDA64, on the page of which device the fan speed will change.

Customize

To change the names of sensors and speed indicators to clear ones, click on the "Configuration" line. To do this, just select any element of the list, and then click on it with the left mouse button. Here, at the bottom of the tab, you can set the desired device temperature and critical.

If the component heats up to a critical level, the utility will automatically cause the fan for the PC to rotate at maximum speed. When the device has cooled to the desired temperature, the cooler speed will be reduced. If form filling causes difficulties for you, and you do not understand what specific values should be entered in these boxes, read the instructions that came with the device, or find the latest information on the manufacturer's website.

After that, click on the "+" icon next to the device name. In the unfolded list, leave a tick just opposite the fan that corresponds to this equipment. Any cooler (fan) can be renamed. To do this, go to the "Fans" tab.

If you want to set the automatic rotation speed of the cooler, switch to the "Speeds" tab. Select the desired fan. At the bottom of the window, enter the minimum and maximum speed in percent. As the upper limit, never set a value equal to 100%, because the cooler itself will be accelerated to maximum when the peak temperature specified on the main settings tab is reached. After the entry, select the check box next to "Auto Edit".

Advanced users are advised to use the "Fan Control" settings section. In it, for each fan, you can set the curve for changing the speed of rotation, depending on the readings of the sensors.

Conclusion

The program for overclocking coolers on the computer SpeedFan will have to appeal to advanced users and overclockers. To all the rest it will seem complicated. An inexperienced user will not easily be able to match the fans and sensors and understand all the parameters. In addition, the normal temperature of the devices and the critical is not always indicated on the manufacturers' websites and in the instructions.
