Dear,

 

My rMBP (allong with horrible image retention) get's overheated regulary. It become to hot to touch and my programs and graphics start to become very sluggish. The laptop becomes insanly hot at the arry above the F keys. Strange enough I've never heard the fans kick in, makes me wonder if they even work..? Is there a way (hardware test) to test the fan's?

 

Thanks

    Ye's.

     

    Using Apple Hardware Test

    You must remove the firmware password, if one has been set, before you can use AHT.

     

    Donationware iStat Pro is a widget that displays system information, including fan RPM.

    You can download iStat Menus and get just about any information you want - temps all around the unit, fan speeds, etc. Download it and post the information concerning temps and fan speed. It's free for two weeks, I think, but the paid version (well worth it) is $16.

    Kindly thanks for the responses. Did the hardware test. My computer got indredible hot again while doing the test, but it say "no problems found"

     

    Does anyone else have his/her rMBP getting overheated, to hot to touch? And as result getting a really sluggish and slow machine?

     

    I will try istat now. Thanks for the tip.

    Ok with normal average use temp of the CPU is 75 degrees celcius. When do intensive stuff it goes up tot 85 degrees. Is this considered a lot? Haven't done heavy things yet, and didn't reached yet the point where it starts to throttle.

    85ºC is pretty hot - I average about 64ºC with minimum use. Now when I'm, for instance, rendering a 3D image in Photoshop, temps can get up to 85º or higher and fans will ramp up to 6700 rpms.

     

    I'm afraid that you're just going to have to take your machine into your local Apple Store or an AASP. Those temps just aren't normal for everyday use.

     

    Good luck,

    Thanks for your reply, My biggest conern is, my fans never seem to go up above 3000RPM. Like now I am just browsing and the temp is 77 degrees celcius, but the fans don't kick in.

     

    With 77 degrees celcius I mean the temp reading from CPU2. That is the correct one to look at right?

    Your fans should be abobe 3000rpm if you're at the 77º mark - as I said, when I'm rendering, my temps and fans go up - nothing to worry about in that scenario.

     

    In iStat Menus, set your fans to 'medium' - they should go up a bit.

    Then I think my computer does have a defect. The fan's should kick in without third party software. That explains why my computer starts to throttle. It doesn't get cooled down properly.

     

    The image below is just from internet browsing. Note the high CPU2 temp and the low fan rate. On top of this my screen has bad image retention

     

    Thanks for all the help.

    Here another one. Temp CPU2 is 82 degrees celcius, but the fan's hardly kick in. Computer is almost to hot to touch at the upper part above the keayboard.
