Should I send my new mac pro back?

    So after almost 18 months of scrimping and saving I finally managed to buy a mac pro! There are a few niggles however:

    Fan speeds:

    From other posters here it seems their fan speeds cpu and exhaust is well under 1000, mine are both spinning at 1800 according to my istat widget (the others are between 6-800)

    Ram consumption: I've just moved from a late 2007 macbook and the mac pro consumes twice as much ram (this may be normal however the macbook can run more apps without feeling sluggish) This may be a hard drive problem though (it seems apple have supplied a rather slow hard drive as standard, I have the 320gb version.)

    Any help with this would be much apreciated.

    Same for me, I've yet to see my mac pro's fan to go over 800 rpm.

    If your fans are spinning @ 1,800 they should be quite "loud", are they?
    Do they spin at that speed right after startup - without any CPU intensive programs running?

    If yes, then there is something wrong.

    Please post your full iStat readings. Here are mine for comparison:

    How do you change istat to a vertical look?

    Anyway here's the shot:


    I think I may know what it is however. I transferred all my hard drive from may macbook to my mac pro using migration assistant. I had smc fan control set to auto start in my macbook. When I tried to use if for the mac pro all it shows is one fan control. I've since deleted smc and all it's attendant files and the istat shot is without smc on, could it be something to do with the migration? If I back up all my files with time machine and do a re-install of leopard would that help?

    Under "i" settings.

    Or you can click on the widget and then press "s".

    I prefer the vertical look because otherwise some
    of the 22 (!!) temperature readings are hidden.

    I would try an SMC-reset before that. Also, you could run the Apple
    hardware test (hold down D when booting from the hard disk). That
    can on occasion pick up a sensor fault which is a possible cause, even
    if unlikely. Your temperature readings - the ones we can see - look low
    enough, certainly not so high I'd expect the fans to kick in like that.
    Also your fan speeds have a '99 look to them. Draw what conclusions
    you will :)

    Ok so after having my mac for almost a week without the fan speed changing, it's randomly decided to go back to what seems to be the norm for Early 2008 mac pro's. Out of interest what should the be the normal temperature range (min-max) for the processors? I'm not using SMC anymore, but when I'm using my more processor intense applications (logic 8/cs3) I want to be sure it's adequately cooled.

    More info needed

    Before I comment on your fan speeds,

    1. How much memory do you have?
    2. Is it all Apple memory?
    3. What's your ambient temperature in the room?
    4. What apps are you running?

    I'd be more worried about your room temperature :)

    At 17C ambient inside the case... brrr... I'm shivering
    just thinking about it!


    If you just want to screengrab the istat widget:

    shift+command+4, then release and then press space,
    click on the widget window and press a mouse button.
    Sounds more complicated than it is.

    macbook pro fan speed is high 2000 rpm

    I am having the same problem on a brand new MBP!
    Does running migration somehow mess up the fan speeds?

    Please see my post here:

    Same here, looks like 600, 500, 600, 800 is the norm...

    did you try reinstalling fan control and manually changing the fan speeds back to their defaults?

    maybe it's possible that even though the app isn't still there, the fan speeds defaults a still higher...

    I would recommend reinstalling with Erase and Install. If that doesn't fix it and the fans are still spinning fast (are they loud too?) it would seem your logic board isn't reporting the correct temps to whatever controls the fans.
