    Hello all -

    There has been plenty of discussions in the past re: CPU, HDD and RAM temperature, but what about the power supply on the Mac Pro?

    My 08' MP reports 70 degree Celsius while the 09' MP reports 35 degree Celsius, while both machines are reporting an Ambient temperature of 27 degree. Why such a discrepancy?

    How about your machine?

    08 MP, 73 & 66...

    Man, WD Hard Drives are warm! My Samsung drives all roll between 28-31 at high usage, 7-10 cooler than WD.

    If you search the '08 MP PSU's, some did run rather warm.

    Unfortunately, IIRC, those were problematic, and had to be swapped out. (There was a part change according to a couple of members who had this). :(

    Looks like wheezy's 08' is running hot as well.

    When you say swapped out... Swapped out by Apple due to their faulty PS?

    08 MP here. 54/51 for the power supply 2 and 1.

    Although my computer is just sitting here, not doing anything extensive.

    Two things to check:

    Does the temperature measured increase or decrease under load?

    What is the PSU temperature immediately after booting the machine
    when it has been left to cool? Is it close to the ambient temperature?

    High readings may be due to the power supply running hot or a thermal
    sensor not working in the expected way.

    Good point. ;)

    As I recall though, the replaced units weren't thermal sensors. I had asked if the PSU enclosure was hot at all, and IIRC, it was hot, not just warm, to the touch. So I figured it was bad Voltage Regs. At any rate, those affected took the systems in, and got replacement units. No reported problems since, so it seems there was a bad batch/supplier.
