    My hard drive temp is averaging around 50˚ (Celsius) isn't that just a little hot?

    Hi and welcome to MR. To be honest if you want any answers that will be helpful you will need to provide more details. Which hard drive? When does this happen? Right after bootup? After surfing internet? After editing video? Have you downloaded SMCfancontrol and manually adjusted the fan speed? We need more details to be able to give you a good answer.

    50˚C isn't that bad, especially if it's in active use. The Western Digital 320GB in my former mid-2007 24" iMac ran in the high 50s depending on the season and the ambient temp, level of activity, etc. The 1TB Seagate in my i7 runs far cooler. It is currently at 23˚C but I am just starting to heat the room in the morning.

    You're certainly not in danger of heat-related failure on a HD at 50˚ nor is it any cause for concern.

    Hard drives are only rated to 55C in most cases. Although there's still a lot of ongoing discussion on what exactly a "safe" temperature is for a hard drive, the general consensus is that high temperatures are much more risky for the hard drive than any other component inside your computer.

    increase the fan speed to cool it down.

    Not to start up this debate again but like everything else there is conflicting data and opposite opinions abound.

    Failure Trends in a Large Disk Drive Population

    A common misconception is that a colder hard drive will last longer than a hotter hard drive. The Google study seems to imply the reverse—"lower temperatures are associated with higher failure rates". Hard drives with S.M.A.R.T.-reported average temperatures below 27 °C (80.6 °F) had failure rates worse than hard drives with the highest reported average temperature of 50 °C (122 °F), failure rates at least twice as high as the optimum S.M.A.R.T.-reported temperature range of 36 °C (96.8 °F) to 47 °C (116.6 °F).

    1TB standard 3.5-inch Serial ATA hard drives - 7200 (rpm).

    Thank you 53x12, I am just using iStat System Monitor. Like I said its averaging a temp of around 50˚. I have no idea what brand the iMac HD's are. I am running Caffeine to keep from sleeping - I'm still not sure the flickering issue has been resolved (Firmware patch applied) - Actually Ive already RMA'd and am ready to return my new iMac but since Ive patched and reset my PRAM and NVRAM it hasn't flicked once, so Ive got 2 weeks to decide if its a keeper.

    No I haven't installed any fan control apps, I would hope I wouldn't need to. I'm not really up on my HD specs as to what is an acceptable temp level.

    if 3rd party software is needed to cool key components then the item is faulty..

    plain and simple.


    why do some people put up with this cr@p?

    I'm not using 3rd party software nor having any cooling issues on my i7. :rolleyes:

    What cr@p? :p

    If components in your Mac are not being cooled properly try an SMC reset. Failing that contact Apple for service.

    50° Celsius is not an unreasonably high temp for the iMac's HD under load, sorry.
