Q: Macbook Pro Retina Mid 2014 CPU Overheating Immediately

Hi, Berk

 

Macbook pro retina mid 2014(Macbook pro 11,2)

i7 4770HQ 2.2Ghz, Intel Iris Pro 5200, and 16gb ram

 

is overheating while I'm using zbrush, after effects, cinema 4d etc. CPU cores temps increasing 95-100C(212F) in 5-10 seconds.(Intel i7 4770HQ Max temp. 100C)

When I stop working process cpu temps decreasing normally in 5-10 seconds.

 

When I try this process, on iMac 2011(512mb intel i5 3.2 1. generation) , not overheating. 

 

Is that normal for i7 4770HQ & Intel Iris pro?

 

Or there is a big problem?

 

Thank You.

 

Best Regards.

MacBook Pro with Retina display, OS X Yosemite (10.10.2)

    Every time I start my retina Macbook Pro  (mid 2014) I hear the fans spin up, and if I look at the output from Turbo Boost Switcher (http://www.rugarciap.com/turbo-boost-switcher-for-os-x/) I can see that the CPU temp is approaching 100degC. Luckily I've already had kids, otherwise I would be worried about overheating my balls (sorry for the overly graphic example).

     

    My only solution so far has been to install TBS - and have turbo boost permanently switched off. This means that the CPU temp peaks at around 70degC, and I will probably gain a little in terms of battery life and longevity of the CPU.

     

    To be clear - these aren't really desktop CPUs - they are dual core rather than their 4 core desktop counterparts - and the excessive heating is just down to Intel thinking they can get away with running the CPU hot for short periods of time (aka turbo boost); this dynamically increases the speed of the CPU on my machine from max of 2.8GHz to 3.3GHz - to give performance a kick. TBH I haven't noticed my machine being hampered by *only* running at a max speed of 2.8.

     

    In reality your CPU will spend much of its time in a much lower power state - take a look at the output from Intel Power Gadget (https://software.intel.com/en-us/articles/intel-power-gadget-20) to see the secret life of your CPU!

     

    So in short, either live with the heat or run your CPU a little cooler with something like TBS.

     

    Best wishes,

     

    Jon
