CPU fan wont increase RPM when under load.

Asked By Williamshore 230 points N/A Posted on - 05/22/2011

Hello members,

I got a problem with my system's CPU fan recently. It stopped to increase its RPM when under load . So, I can't use my system for heavy duty works which is obviously a big problem for me.Because, my system is getting too hot when I use it for heavy duty works. It actually occurred after I upgraded my video card to a GTS 450 from the old video card (8800gt).

Kindly, help me in this. Thanks.

Dear Williamshore,

Firstly if you have mentioned your system configuration that should be easier to identify the problem . If the power supply to the CPU is not enough to meet the total demand , this would be the reason.

The power consumption of your video card is more than the previous one . Your issue might be related with the power supply. You can control the processor fan on the BIOS setup that is according to your motherboard manual.

If you want to speed up other cooling fans you need enough power supply.

Hi,
The BIOS configuration of your motherboard should print the fan RPM in some section of its program. Check RPM value and verify for something strange.

You must increase the clock of  your CPU, if the fan does not respond and don’t increase its RPM, check the fan connections, maybe you can have connected it on the wrong side or you have chosen the wrong connector.

"Of course, it’s not a software problem."
