    I recently had my standard 1TB hard drive swapped out of my 27" 2009 iMac for a Samsung 840 Pro SSD. Performance wise, it's a gigantic step up.

    But is it pretty common for there to be fan or temp sensor issues once this sort of replacement is made? Because the HDD fan on my iMac has been running on full tilt since the replacement.

    I installed Macs Fan Control and the HDD fan was spinning at 3000RPM, while the CPU fan was at under 1000. It sounded like a vacuum cleaner. Anyway, I'm guessing this is pretty common but wondering if I should take my iMac back to the shop where I had the work done. I'd rather not have to run background fan control software if at all possible. But, if this is the price I must pay for a major performance increase, that's fine I guess. Thoughts?

    If that were possible without disassembling my iMac I might consider it.

    I found less obtrusive software to deal with it called SSD Fan Control.

    If you had this done in a certified shop, I would def give them a call and ask what you should do. In my eyes, it's their responsibility to either inform you or somehow fix it.
