    I put all the fans up to 1000 but Power Supply stays at 599.

    Any thoughts why it wont go up?



    Also whats a safe temp for harddrives? My HD:macintosh drive was around 39C- 41C when I put the fans on higher. Now its at 37



    and its only 60degrees out today and my room is already over 70 (dam attic ) i wont be able to use my computer when its 100 out

    mine does the same - at about 600 for the power supply. Guess SMC is not able to spin that fan up...

    Under no load, w/ 2 drives I am at 32C in a 70F room. CPUS are at 25C.

    A "nice" safe temperature for most consumer HHDs is room temperature ~ 36c. That's for a typical HDD rated at 50c/55c MOT. This is according to Seagate and that sounds about right to me too. Such drives should always be kept under 40c if you can. I mean if you want "nice" - and nice is good. :)

    BTW, my PSU fan speed increases when I set it using smcFanControl. Are you using the newest version? I'm using a 2006 Mac Pro tho. I guess there could be some difference.

    I'm also on the 2006 Mac Pro and my PSU does the same thing, so it's not something to worry about. I'm not sure if that's a problem with the PSU's fan controller not working or if it's just something in the software.

    And as for the hard drives, I have just two in mine at the moment, and both are usually at the ~40c to ~50c point. I didn't mind checking the technicals for a recommended temp, but hey- no problems so far.

    I have an late 2007 Mac Pro & I'm unable to adjust the power supply fan speed also. I've read that this is a common complaint.

    My hard drives are usually around 37 to 40c

    and thats only when its 70degrees outside.

    During the summer (85-100f outside) I have to run an external box fan into my mac pro to keep that temperature or just turn it off.. i'm in an attic
