I just installed an AMD 64 3400+ along with a stock Cooler Mater in a chaintech zenith znf3-150 board. I went to check out the pc health tab in bios and it said my fan on my cpu was going 1800 rpms! It's suppose to go 3000+ rpms. I looked it up on cooler masters site. My cpu temp was 68 C and climbing. I was like "hell no" So what could be the problem? I can't figure out why it's going so slow... I was wondering why it was so quiet. I may go out and buy a new heatsink+fan tommorow, but I want to try to fix this fan problem.... if possible.
