    I was playing with a early 2008 mac pro in the store. Downloaded
    iStat Pro and noticed the HD fan was running at 799rpm. Now, I
    recall people saying in the past that the HD fans in the Mac Pros
    were running too slow (default used to be 500rpm). Has Apple
    bumped the speed up a few hundred rpm?

    The new MP run hotter due to the faster FSB and need more cooling.

    Still less than the 1000rpm idle speed on my PM G5!

    Anyone with a new Mac Pro can you confirm what your default lowest RPMs are. On my 2.66 Mac Pro the defaults are (from iStat Pro):

    Exhaust: 599 rpm
    CPU Fan: 499 rpm
    Power Supply: 599 rpm
    Hard Drive: 499 rpm

    99 this, 99 that. Come on Apple, let's have
    some nice round numbers for our fans! :)

    A faster FSB per se doesn´t have anything to do with increased cooling needs for cpu, hdd and psu. The Xeons used should all require less cooling than the previous gen parts. The mobo chipset may in deed dissipate more heat but that should be taken care off by passive heatsinks not increased rpm on the chassis fans.

    Maybe the new ones will introduce decimal points. How's 598.7 rpm sound? :p

    i've been wondering about that. so they're smaller and cooler per core, but if there's twice as many cores, they're still going to put out more total heat, right?
