i havent restarted for a day. and the only time my cpu fan ever hits 6,000RPM not 30,000. is when im hardcore gaming. im hoping this numbers an error. if its real. it must have been when i was at school. and im planning to get a new cpu fan cooler since the 6,000rpm sounds like a jet engine on the stock cooler. but that fan number i have no idea what fans that connected to. as i have 4 fans. 3 led 1 non led 1 heatsink and 1 on my gpu. my gpu idles at 2,000rpm. 29c* and my cpu idles at 3,500RPM 35c*. so im completely clueless. as the 3 leds are labeled 2,000rpm and the case fan thats not led is labeled 1,500 rpm.
while looking at the output of the program, unplug each fan you are comfortable unplugging (aka case fans) and see when it goes away. You can then hopefully find which is causing it. Perhaps it's a 3 pin fan in a 4 pin slot put onto the wrong 3?
