Cheers for the replies. Got a whole bunch of monitors cpuz,gpuz, speed fan (karlsnooks cheers forgot that one), hw monitor, and the list goes on.
none of the monitors show any thing out of the ordinary(system is only running the desktop).
I have it under control using extra software, but i was wondering why,? i could understand if it was the gpu fan but not the cpu fan.
Still its under control for the moment i am going to run more tests, change a few settings just to see if i can get to the root of the problem.
Any more ideas most welcome cheers
