Well, my cpu fan/cooler whatever it is is going around 4500 rpm all the time, and the noise is unbearable, normally its around 2000 rpm, i believe. And The cpu temperature is aroudn 40 celsius.

How can i slow the damn thing down?

its been going on since yesterday, when i ended up taking out the bios battery due to other problems which are fixed now. the bios settings are reseted when the battery is taken out arent they?
