Is 60 Degrees too hot for WD Caviar Black?

    Just installed a 1.5 TB WD Caviar Black hard drive in my early 2008 24" 2.8 ghz imac with 4 mb ram.

    The temperature reading via istat pro and Temperature monitor reads a consistent 60 degrees Celsius. This is with light activity and the cooling fan running at 1600 rpm.

    It is hot today, 78 degrees Fahrenheit in my house.

    Should I be concerned ?

    That is the hard drive in my iMac and i happen to know 60C is the max temp Western Digital say, you may have to up your fan speed...more

    I have a 1 TB Black Caviar in my 24" iMac. Right now it reads 58 degrees C. Fan's running at 1947 rpm. I just raised my fan speed to 2230 rpm. Still 58 degrees..

    Seems like that is too hot basically an idle machine. I guess I'll contact WD tomorrow and see about a replacement

    Called Western Digital and they said that as long as it only gets to 61 (its at 61 right now) it should be ok. Told me to wait and see what happens. I don't really like that idea. I', wondering if I should return it for the same drive and hope for better results, or if I should go for a different brand/model entirely. The drive is performing great, hate to lose the performance, but the drive running at max temperature doesn't seem like a good idea to me.

    Right now fan has to run at 3200 rpm to keep temp down to 55.

    Anyone have an opinion on whether I should try an exchange for the same drive and hope for cooler temperatures?

    Call Apple and see what they say. I don't think it's too much of an issue.

    Over 55C and its starting to cook. Over 60+ and its being fried. Especially at sustained 60C. If Apple going to admit this max 60C threshold limit? Bet they say, "drive until it automatically shuts down" - which in my books is "too late - damage is already done" in my books....

    My HD runs between 34C and 43C. I've yet to see it climb into low 50Cs.

    To help its insides keep cooler, suggest:
    - Installing 3rd party fan control software and "increase" the factory default of fan speeds. Especially if ambient temp is above 75F. For example, iSlayer iStats Menu 3.
    - Install a little 6-8" silent running fan behind the iMac screen and blow air against the back of the iMac.
    - Remove the memory insert cover (at bottom on screen) to allow more air flow into bottom of iMac chassis. One cannot see the bottom of the screen anyway.

    These low cost proactive cooling items work on my iMac....

    That sensors are off, but if it's running on or near redline, I'd take it back and try another, at least you have a benchmark to begin with.

    How is it possible that the hard drive is hotter than almost every other component in the computer when it shouldn't be generating anywhere near as much heat as the CPU for example. Something doesn't seem right, maybe the part of the computer with the hard drive behind it is in direct sunlight?

    As others have said, just try and keep the general temperature as cool as possible and monitor the temps for a while.
