CPU Fan spins too fast

**Gunslingerjh** · 03-13-2014, 03:08 PM

So, the CPU fan of my PC is spinning at +/- 4300RPM for about a month now. It's really noisy and it's driving me mad!
I already tried some stuff, but nothing has worked so far..

Any help would be appreciated!

Things I already did:

- I ran compressed air through the entire computer. There was some dust caught beneath the cpu fan, and some in the gpu fan. Everything is totally clean now.

- Removed old dried up paste, and applied new thermal paste on the cpu/cooling block

- Using speedfan, I tried to decrease the RPM. The only fan I am able to modify is the GPU fan. The CPU's temperature is very stable now.
