    Hello everybody.

    I just swapped processor from T2250 1.73 GHz to T7200 2.0 GHz. :D

    Now... what kind of temperature increase should I expect when going from 31W to 34W ?

    And is 70 Celsius too much under continuous load ? Old processor was 62-63 Celsius under load. I probably put too much of thermal grease anyway.

    Also, anyone had experience with IC Diamond thermal grease ? Was it so hard to spread ?

    Try undervolting.

    I upgraded from a Celeron M 420 (TDP: 27W) to a T7600 (34W), and saw max temps of 80*C. When undervolted, my max is 57*C on both cores. :)

    You could try using Arctic Silver 5 the next time you remove the heat-sink.

    Yes, I'm just reading about undervolting :)
    Correction: now max is 75 C...

    I used old Zalman Silver 75AGS grease...

    So I got from inital 1.1875V to 1.0375V at max speed/multiplier which is 12x.
    Lowest mp is 6x with 0.9500V.

    Temp drop from 75-77C to 68C. Nice. And it's not over yet as I didn't test less Volts yet. :)

    you should be able to knock the voltages down to under 1 volt (0.950V) for most of the multipliers.

    Not every CPU can undervolt to the same level - test at EVERY step, even for just a minute, then give yourself a small cushion and give it the ol' overnight stress test.
