What To Do When Your PC Shows CPU Fan Error?

More than 80 percent of cases are that the reason behind this is nothing but the overheating of your CPU. So, first, let us discuss some primary methods related to hardware by using which you can avoid overheating your CPU.

1. Try To Move Your PC To A Colder Place

Leaving your computer in a hot or sunny place might cause it to overheat and shut down. Place your computer in a cooler area, and avoid placing it directly in the sun. We suggest you install it away from those positions of your home interior where heat exposure is high.

2. Clean The CPU Fan And Air Vents

A CPU fan error occurs when dust gets caught in air vents and causes the fan to behave abnormally. To Solve this, You need to clean the CPU fan and air vents.

Turn your computer off, remove it from the power source, then open up the casing for this step. With an air cannon or canned air, clean the interior and remove dust once it’s been opened.

To clean the CPU’s air vents, remove the brush from a vacuum cleaner and use it at full power to suction out any dust or debris. You can also use an airgun or bottled air to blow the dust away. In addition, you should clean the CPU fan.

3. Check The CPU Fan For Loosening

Having cleaned the CPU fan, do not forget to close the case again. Physically inspect your device’s fans to make sure they aren’t loose or out of place. With a screwdriver or adhesive, you should be able to secure your fans back into position, depending on the model of the CPU.

Ensure that all electrical equipment is switched off and unplugged from all sources of power before inspecting it inside. When shutting your computer off, remember to select Shut Down rather than Sleep.

4. Say No To Overclocking

Overclocking causes a significant rise in system heat, which the normal fans are unable to handle. This might result in circuit damage, repeated shutdowns and overheating problems. So, we suggest you avoid overclocking the CPU.

5. The Installation Location Of The CPU Fan

CPU fan location and installation depends on the type of motherboard or processor you are using. The CPU fan lock structure are different for Intel and AMD based processor.

CPU fan must be linked to the motherboard’s CPU header post installation. If it’s connected somewhere else, the fan might run when the computer is turned on, but it won’t properly cool the CPU, which is its purpose.

In most of the cases, the CPU header comes labeled “CPU Fan,” but even if it isn’t there, the three holes for the fan’s three-pronged connection make it easy to locate. Thus, now you can identify the spot exactly where you have to install the CPU fan.
