    Hey,

    My 2009 (i7) iMac's hard drive is 59c... is that too hot?

    It's quite hot but nothing extraordinary if you just did something intensive.

    It's always 59c. It never changes from what I can remember.

    For comparison, the CPU is 45c, the GPU Diode is 64c, Ambient is 21c, Memory Controller is 52 and Optical Drive is 51.

    Just out of interest how are you finding out: System Profiler doesn't seem to list it...

    Very interesting, thanks. I don't really use Dashboard much but that's an interesting little tool. For reference the (5400 rpm) drive in my MacBook Pro is currently being reported as 33ºC. If it never ever changes then I would question the accuracy of the reported number.

    Hmm, that sounds quite warm for the HD. Mine is at 52c and CPU is at 45c and GPU diode at 59c. Are your fans running at the default speed?

    No worries, it does change but not much. It's currently 58c.

    Why would my hard drive be ~12c hotter than my CPU and on par with my GPU?!?!
    They are unchanged by me.

    If it's being used continuously? What do you have running? Anything that's streaming data too/from the drive continuously? How much RAM do you have? Is your machine paging all the time?

    I wouldn't say it's been used continuously at all... I've got Safari, Mail, iTunes (nothing playing), Activity Monitor, XCode 4.
    I've got 12GB of RAM and my page outs / swap used are both 0 MB, page ins are 313.2MB. Not much is happening at all.

    And no, nothing is streaming data to or from my machine.

    What sort of hard drive is it (manufacturer model etc)? Some run hotter than others.

    Because it's much closer to the GPU, see the attachment

    Ah I see... that makes sense. What temp does your GPU idle?

    I think I'm experiencing some kind of hard drive throttling due to high temps; under Windows when I'm playing a game (League of Legends), if I'm downloading from Steam (~2MB/s) I get stuttering FPS every time, stop DL, no problem.

    Currently, both diode and heatsink are at 59c. Safari (no Flash) and Adium are the only active apps so GPU should be idling.

    Is League of Legends an online game? I remember my friend having the same issue with CoD4 because downloads used all the bandwidth thus the game lagged (it was online). Hard drive isn't really used when gaming as most of the data is saved to RAM (thus the loading times ;)).

    Ah, ok.

    Yes, it is, however, I've got 3.7MB/s download bandwidth and was only using 1.5-2MB/s for the DL.

    I'm not experiencing lag, but choppy frame rates. Without the DL I'm 40-55 FPS constantly; I never drop below 40. With the DL, it goes to 20, 40, 30, 55, 25, etc... mostly in team battles (lots of stuff happening).

    i never understood why apple is placing the harddrives in the iMacs since the first G5 always in the hottest spots (above gpu and cpu ) because its the harddrives that cant stand high temps most manufacturers recommend for their harddrives below 60 celsius , and physics i had in school years ago said heat will always rise , but if i look into iMacs no matter which generation i guess my physics teatchers might have been wrong and heat falls down , but why if thats the case did they fit fans which blow the heat to the top :confused:

    my temps on the core duo 17" iMac read
    cpu 41, GPU 65 ,hdd (smart readout ) 47 always celsius of course nothing doing really apart i power a second monitor and safari ,mail , seems to be fairly normal
