    Dear Anyone,

    You are requested to give me details of effect of TEMPERATURE
    variations on CPU performance

    for Intel Pentium-4/ AMD AthelonXP processor.

    If I am keeping the CPU under cold controlled atmosphere(<10degC),
    performance will be increased?

    Thank You!

    As long as the die itself does not get overheated *and* there is not
    excessive temperature cycling, then the CPU has a high probability of
    lasting many years.
    Temperatures less than 25C tend to make the signals in the part move
    This means that a cold (<10C) CPU will more likely to be unreliable if
    overclocked, and warming it up to 25C would tend to increase reliability
    for the same overclocking.
    I would not be surprised if some CPUs would not work at standard clock
    rates, if cooled to -55C (the low end of MIL spec temperature range).

    Thank You!

    Could you please help again?

    What can be the best operating temperature range for a CPU, obviously
    above 25degC, but upto what temp. it can process data at peak speed?
