I just built this new PC, I am running and AMD 64 athlon 3400+. I keep getting CPU fan error for some reason, even though my cpu temp is 40c. I've just ignored this recently. But I want to overclock to get my processor to run and 2600mhz because right now it is only run at 2200mhz. Anyone have any idea on why this error might be happening? I also think that when it is running 2200mhz, it should be A LOT cooler then 40c. Any ideas/suggestions?
