    You should be worried about the heat too.  Excessive heat destroys stuff and/or shortens the life span!

    Hi jkd22,


    i know this too but i also know that this is called "natural obsolescence" and i also know for apple is important to have a more silent device than a loud. So the fans are only speed up when it´s 5 before 12. This is my view of this. Sorry, my mother language is german.


    I let them check the heat too, but what me really p*** off are the dead pixels and they count (nearly one per month).

    I might agree for 80-90 degrees C under load but routinely reaching 104 out of an absolute max of 105 is unacceptable.

    I've bought the new Late 2013 Macbook Pro from October.

    At first, I thought this laptop is really cold to the touch (within the first days of purchase and idle-work like browsing) - right until you run a VM, or a otherwise trigger the GPU/CPU in full load.


    Now, it's like it's settled on high temperatures for good (even though I only ran those demanding applications temporarily - and not using it now). Before it was maximum 60-70 - this has risen to 80-100 within the last two days were I for the first time used my dedicated graphics card.


    I'm pretty sure the NVIDIA Graphics Card is the cause. Using gfxCardStatus ( and switching to Intel HD Graphics makes a huge difference and lets the computer lower to 40 celcius at idle.


    I'm sorry to say, but not all heat issues are gone with the latest Macbook Pro - at least, the power management and throttling of the dedicated graphics card could be better - otherwise we wouldn't see temperatures and spikes like this.

    I have big problems with or without the dedicated graphics card.  It's the CPU cores that heat up the most not the GPU although the GPU is never actually "cool".

    smcFanControl (


    I tweaked mine a little above the default profile "Higher RPM" and made it default under AC Power / Charging.


    In this way I can stay cool and still avoid the noise.


    (NOTE: GPU is in left-hand side, and so I run left side a little higher RPM than the right side)

    Will it work on Mavericks?

  • dezzadk Level 1 (0 points)

    Of course. Otherwise I wouldn't have written it in anno late 2013 ...

  • golfnut1982 Level 1 (10 points)

    Thanks. Website said mountian lion, thats why I asked. Sounds like its working for you.

    Mine is now on the THIRD logic board specifically because of heat issues. 


    My has been going to over 100C even without really heavy loads. 


    Their strategy was: 1.) Deny problem, 2.) Replace logic board, 3.) Deny problem, 4.) Replace logic board again, 5.) Stone wall.

    I have a mid 2012 MBPr. Was playing Assassin's Creed 4 on Bootcamp in Windows 7 and noticed it was getting pretty hot. I have the window behind the laptop open slightly and there is a cool breeze. The laptop is sitting on a book such that a good portion of the bottom is not covered. After looking at the temperature graph, it seems like I may be shortening the life of this laptop by playing this game (and others). It peaks at 105 degrees (Core0) and has trouble stabalizing.


    It does go down slightly over time. I may try this again. It would be interesting to see if it goes down to 90 eventually.

    I tried again with no book under laptop. Instead I used two thin plates wrapped in aluminum that keep the macbook off of a wood surface. I also should note that the last test I did was running two displays. The one below is running the external display only. Core0 still goes up to 105, but slowly makes it way down to the mid 90s. It's like a heat chamber test without the heat chamber.

    To make this better run Disk Utility

    or if that doesn't make it any better I sugguest buying cleanmymac2

    I got a new MacBookPro Retina with 2.3 Ghz, Intel Iris Pro and Nvidia GeForce GT 750 M.


    No such heat problems as with my Mid 2012, 2.7 GHz, Intel HD 5000 and Nvidia GeForce GT 650 M.


    The main difference:

    In opposite to the Mid 2012 MBPR, where the use of the Nvidia 650M slows down the system (instead of increasing performance as expected), the new one dramatically increases performance with the Nvidia GeForce GT 750M up, specially of apps using much graphics power such as FCPX, iPhoto, Aperture etc.

    E.g. film editing directly on native H.264 can now be down without the need of optimizing footage before. With the new one it is really fun to work with, the Mid 2012 was definitely not usable.


    Absolutely no heat issue with the MBPR late 2013.


    I assume there must be A LOT of Mid 2012 MBPR 15 out, having this heat problem and Apple does everything to avoid a product recall of all faulty MBPRs. What is in fact really poor by Apple.

    I have an early 2013 MBPR which I bought right before the new batch arrived. From the start it went to high heaven with temperatures - seriously, nothing heavy happening, browser, Photoshop and iTunes, and it goes to 80-90 degrees and Temperature Gauge is having a fit with one of the cores going up to 100C. But the fans are still slow as usual. I installed smxFanControl and I have to run it to cool down the laptop. The laptop never speeds up the fans on its own. ***?


    The guy next to me in the office bought the same exact model and his laptop is heavily 'breathing' when he's using Photoshop. This is very frustrating.
