Forum Question: Using Handbrake OVERHEATS IMAC

I used Handbrake to Encode some DVD videos for my Ipad and it overheated the rare top part of the imac. I wasn’t sure if its normal so I aborted the process.
Can I continue using it with no worries ?

    What do you mean by “overheats?” If the Mac was overheating, then it would shut down automatically. If it didn’t do that, then it wasn’t too hot.
    Handbrake processes a huge amount of data as fast as it can. So it uses your processor very intensely. But your Mac won’t overheat — it will protect itself.

    By Over heat i meant it felt very hot ! Touching it was fine ! But its never got this hot with normal use.

    First time I used the optical drive for over 45 minutes continuously…

    I wonder if i left it doing the same job for 5 hours (because the DVD has many videos to Rip) would it be adverse for the Imac ?

      Computers are meant to do repetitive tasks.
      But, yes, “using” your computer will have an adverse affect on it. By that I mean that the more you use it, the more you use it. Know what I mean? The best way to protect your computer is not to use it — but of course that is not why you have a computer. But using it — typing on the keyboard, changing the pixels on the screen, moving the mouse, spinning the drive, etc — will wear it down and it won’t last forever.
      But to give some perspective, if you were a video editor or animator you would be running intense programs that would be heating up your Mac all the time. It isn’t unusual.

    Oh yea Hanbrake is CPU intensive but it’s meant to bs that way. When I Rip a DVD using Handbrake in my i7 iMac, I can see all cores almost full. I have all 4 cores max and all 4 virtual cores max out. And let me tell you the fans start spinning up and I turn the fan on in my room because I know it’s about to get warm. Also when my wife and I use aperture for photo editing, same thing. The CPU is a number crunching device and when called to do intense calculations it’s get hot. But if it gives you any sense of comfort, a recent article I read showed that the least computer part to fail is the CPU. The highest to fail? The Mother Board!

    I’ve found out to have the same problem with Handbrake and have discovered a way to prevent the CPU temperature rising too high while encoding a file. Especially when using the .264 codec. Under the ADVANCED button in the options underneath the file destination section. There is a section labeled “Something” optional string. Here you are able to type in the amount of Threads/Cores Handbrake is to use during it’s process. Default(Blank=Use All CPU). Try copying and pasting this:
    :threads=x (where x is the number of threads you want to assign the program) In my case I have an available 8 threads, I have mine set at 4, yes it takes a little bit longer than using all 8 to encode, but I never come back to my computer after a 12-20 unit queue and it has shut down giving me that annoying beeping sound half way through the queue. Hope that helps
