    I have been contemplating getting an octo core mac pro but I have been wondering one thing. What is the fan RPMs at idle? Can someone download the iStat Pro widget from apple and let me know? And after you see the idle rpms kick it up and do something intensive and tell us what they reach to please. Dying to know just how different an 8-core is from a Quad. Thanks so much.

    I could try it out when I get home, but I also run smcFanControl to bump up the minimum speed the fans spin at, since my 3rd party ram gets a little hotter than the stock modules... And when you say idle, you mean, for example, you've just booted up, have nothing in your startup items, don't launch any apps, and let it run for awhile?

    Yeah, just basically sitting there turned on for a while to see how fast the fans are spinning at. While you are at it can you provide idel temps? Thanks.

    Since you started this thread I would like to add a question related but not worth starting a new one.

    Is the power supply the same with the quad and the octo? I imagine 8 cores at 3ghz each drawing double the current --which is a lot-- would need a beefier PS.

    Thanks

    While your question makes sense, I think it highly unlikely that the Mac Pro Octo has a 2,000+ watt power supply.

    8-core is quite expensive, and most people who "need" all of that power still are running stuff on their old G5's. Or they upgraded to the new Mac Pro when it first came out.

    i almost never hear the fans, even when doing heavy duty stuff

    Interesting. My Quad 2.66 idles at 30C with fan rpm at 500 also. Nice to see its quiet.

    just 500 rpm... Wow!
    My MacBook Pro fan rotation speed is 1900-2000 rpm with a temp of ~50C.

    well the fans in there are much larger and an can move much more air at a slower speed. Also I think there are 4 or 5 fans as opposed to 2 in your MBP.

    CPU
    Exhaust/Memory
    PCIe slots
    PSU

    You got a new Mac Pro? If so, how are you upgrading?

    My 8 core mac's cpu fan also idles at 500 rpm. I've just started encoding an .avi file to .mov. After 10 minutes one of the CPUs got to 70 degrees c, and the fan speed ramped up to 660 rpm, where things started to stabilise. (CPU idle time dropping to 65%)

    Mind you this is with imovie which doesn't seem to make use of all the power available. But you really can't hear any difference in noise levels. You hardly notice it, just a faint hum

    Nice. Boy, I am itchin to buy but I know that the xeons are dropping in price in July so I think I should wait. Wait another month and I get leopard for free. What to do. Money burning hole in pocket. Common sense says wait, but oh do I want to sit down with my 8 friends and have fun.

    Someone talk me out of it. I think I might end up at the apple store in a few hrs to make purchase. STOP ME!
