    Hi, My CPU's Normal opperating temperature according to the bios, is 71 celcius.
    my proccessor is
    Intel Pentium D 935 3.2Ghz

    When the proccesor is underload it only rises up to 75 celsius, after i reboot and check the bios.

    yeah you need that stuff, well I would go buy some Artic Silver 5 heat paste or similar, throughly clean the bottom of the heatsink & cpu with 90% alcohol and cotton balls, both surfaces have to be clean, then apply thermal paste small amount, size of a BB, and smooth out with a credit card until a very thin layer covers the cpu, thickness of a sheet of paper or less, then reinstall the hsf

    why the heck intel went with this crazy set up I dont know, the socket and pin idea was just so much easier. You dont see this kind of thing with AMD socket 757/939/AM2

    so now youre looking for pin damage on the MB instead of the cpu whoopdido, cpu is a hell of a lot easier to fix/replace IMO

    But you do see it in the 2nd generation Opteron, socket F (1207) processors and you will see it a lot more as AMD gets further into 65nm and 45nm architecture.

    In a case with good thermal design a PD 935 should idle around 42c. The thermal spec for the PD is 63.4c ThermalTrip should occur at approximately 78-79c


    EDIT: Correct spelling
