SpeedFan tells me this: Screenshot: When idling Temp/Core0/Core1 are ~60C and CPU Fan is at 4000 RPM. I have to say that I cleaned my fan/cooler yesterday but I reattached it as it was before and I can hear it running fine. I am a bit worried. Could I have done something wrong which resulted in these stats? I never used SpeedFan before, so I don't have any before values to compare.
