So my PSU fan speeds up like crazy with annoyng loud noise at every first pc start up in the day,or after long breaks of time,when windows loads up it becames quiet ,how can i stop this ??? tryed something with speedfan and didn't worked. btw cpu fan spins too fast ,sometimes 3100-3200 rpm with stock lga 775 intel cooler,usualy highest cpu temp 63 c,(when i quickly minimize after logn gaming) ,(core 3 duo e6300) can i lock cpu fan speed ,or prevent from reaching too high cuz about 2500-2800 rpm is really enough for my cpu...
