    or 53 Degrees C

    According to smcfancontrol. Is this normal, thats crazy hot.
    And none of the fans are doing anything:
    ODD 998rpm
    HDD 1199rpm
    CPU 1200rpm

    Is this normal? Id figure the fans would at least turn on or something.

    Mine gets that hot sometimes, but not for extended periods.

    Maybe you bought the iToaster?

    Do your fans ever turn on?
    My temps seem to just keep climbing and climbing, and after glancing up to see a sizzling 127* i decided to manually kick the fans in.

    It will usually idle around 100 or 108. the only time is below 80 is either on startup or after i let it sleep for an hour or so.

    That temperature is normal. Shouldn't worry about it at all. Its when it reaches 70 or 80 celsius that you should be a tiny bit concerned. If it reaches 100 celsius then something is wrong.

    Ok, thank you very much, thought I was going to have to interrupt my science fair regionals weekend to replace my baby :p.

    On a side note, I bought my first suit today and boy do I like it.
    (couldve bought a macbook for hardly more though)

    Depends on where the 53 C is. Betcha a six-pack your internal HD is
    spec'd by the manufacturer for either 55C or 60C maximum ambient
    operating temperature (ambient = Hard Drive Bay 1). Heat kills HDs.

    In front of my MacBook Pro
    Totally normal temp. My MBP gets up to 200 when I'm doing a lot of editing and such on it, but it's averaging about 113 now with only Safari open.

    oh noes!

    is there a specific spot that smcfancontrol gets its temperature readings from?
    This is from the apple site: Operating temperature: 50° to 95° F (10° to 35° C)
    Is 'operating temperature' idling, or doing stuff. because i only had itunes, safari, adium, numbers, and quicksilver open.

    I could believe that 130* is normal, but 200!?! You must have steel legs to set that thing on your lap.

    I don't know about smcFC, recommend grabing a copy of
    'iStat Pro' or 'Temperature Monitor' from macupdate.com
    to see all the temperatures.

    The "10C to 35C" is Apple's spec for the air temp in the room
    where the iMac is operating. The 55C or 60C spec I mentioned
    earlier is the HD manufacturer's spec for the temp inside the
    iMac case in the vicinity of the drive (i.e., Hard Drive Bay 1).

    If the iMac fan control logic is working properly, it should
    adjust the fan speeds automatically to keep the internal
    temperatures reasonable while either idling or doing stuff.

    Your temps are nice and cool. Mine is nearly as good as yours, just about 3 degrees warmer on the CPU front. When gaming, the CPU temp reaches 65 degrees celsius which is still good. When it reaches 90 degrees, that when you should begin to worry.

    those are right in line with mine too.

    Mine averages about 120, so no worries. And the highest I have seen mine get is around 170, but i don't do any video editing. My 170 was using pixelmator fooling around with some large photos.

    New iMac and Extended MacBook/Pro Fan Control Versions

    I've generated 2 new versions of Fan Control, one for the Intel-based iMacs and one for the MacBook/MacBook Pro which has some extended control capabilities over the original Lobotomo Fan Control version. For screenshots and (free) downloads (with source code) see:

    iMac Fan Control

    Extended MacBook/MacBook Pro Fan Control

    The iMac version allows separate sensors to drive the control of each of its 3 fans and the extended MacBook/MacBook Pro version allows fan-control via the CPU and/or GPU temperatures (useful if you play games on your laptop). There are also some other minor enhancements (see the ReadMe files).

    I've also tried to make it easy to adapt the source code for other systems ... e.g., a version for the Mac Pro that uses different sensors to control different fans (or groups of fans).

    Hope these are useful to others.

    BTW, there are some Mac Pro versions available via this forum posting.
