Learn how to boost the speed of your CPU fan so your computer can avoid getting overheated.

If your PC heats up frequently while you’re using it for simple tasks, you might be comforted to know that you’re not alone—this is a common issue that affects PC owners everywhere, regardless of the operating system they’re using.

There are many reasons why your system can get overloaded. If you’re doing graphics-heavy activities like playing games or editing video content, this could be the primary reason for your system reaching higher temperatures. You may be aware that if the heat levels in the computer do not drop and continue for a while, it can result in damage to certain critical functions.

There is a fan provided in every PC to cool the system from the interior to exterior. These fans have to increase their speed in order to achieve your objective of keeping your PC cool.

There are two ways to do this. But before we get to the steps, it’s important to understand a little more about how the CPU cooling fan functions.

There Are Limits to PC Temperature

The general understanding is that the temperature inside the PC must be limited to around 50 degrees Celsius or 122 degrees Fahrenheit. The upper most limit is considered to be 70 degrees Celsius or 158 degrees Fahrenheit.

For the long-term safety of your computer, you must try to keep it from getting heated up to abnormal levels. The fan that comes fitted with the system has a speed that is represented by the RPM (or rotations per minute) of the blades.

This can be increased through a software solution which acts as an external resource.

The other way is to make changes via the BIOS settings.

Install Third Party Software: SpeedFan

SpeedFan is a free software program specifically developed for Windows-run PCs. The software application has a versatile capability in monitoring the inside temperature of the PC and it can automatically increase the speed of the cooling fan when it notices the temperature going up.

Once it’s set up, SpeedFan can make sure the temperature in your PC is maintained at the optimal levels all the time.

Since downloading freeware can come with some risks, follow the steps below:

  1. Go to SpeedFan’s official website and download the program.

2. Once you download and go ahead with the installation, look for the adjustments on the page.


3. There will be buttons indicating the GPU and CPU fans.

4. Against each there will be the choice to fix the fans’ throttle.


5. You can select 100% throttle there.

6. The current temperature of the CPU is displayed on this dashboard.

7. You can also choose between regulating the fan speed manually or automatically

manually or automatically

The SpeedFan software should now be ready to assume the function of controlling the temperature of your PC.

Boosting Fan Speed Through BIOS Settings

The other way available for you to manipulate the speed of the cooling fan is through making some changes in the BIOS settings.

NOTE: It must be mentioned here that for purposes of this exercise, a PC run on the Windows 10 OS and the motherboard of a reputed make that has the settings for the CPU fan within the BIOS settings is taken.

Here’s how you do it:

  1. You need to reach the Settings panel first. Click the Windows key and the letter ‘I’ together.
  2. From the Settings window, choose Update & security.
  3. Click on Recovery from the menu you see on the left side.
  4. The next window has an option Advanced startup.
  5. Now click Troubleshoot, then Advanced options.
  6. From the ensuing window, select UEFI Firmware settings.
  7. Click the Restart now button. This leads to your PC rebooting with the BIOS/UEFI settings window.
  8. Look for the fan configuration settings and go by the menu the particular motherboard has for altering the fan’s speed settings.
  9. Once done, you can exit these and restart your computer the normal way; this is done through clicking the Save changes and Reset option.

The changes you made will make sure the CPU fan speed is boosted. On the occasions when your computer gets heated beyond uncomfortable levels, these solutions will definitely help it drop down. Some people experience the fan becoming noisier with its speed increased. This is acceptable to them as long as the PC is kept cool.

If the nature of usage of your computer is such that it is bound to get overheated, then you may have to look for other options. One way could be to go for higher rated PCs the next time you invest in a new computer. For instance, if you buy gaming computers, they should contain a CPU fan that has higher speeds and cools faster. The GPU and the motherboard are included in the construction of the system to keep the temperature of the PC in check.

Of the other points to keep in view, SpeedFan’s maintenance functions may not work on laptops, as it is designed for desktops. But it does offer the option of adding an extra CPU fan with some changes being incorporated, as explained above.If you are buying a new PC, many of these can be avoided by looking in-depth into the specifications, and if you are buying a customized PC, you can ask the vendor to fit a more powerful fan to start with.
