Q: MacBook Pro Overheating [FIXED]?

I think i found a solution and the reason to why the macbooks are overheating. The cause? The CPU is doing all the work.

 

I watched the cpu and gpu temeratures. My GPU never got too hot(50 c at max?), basically just the heat from everything else heating it up. Meanwhile, my CPU will be up at 80-90 degrees celcius.

 

System Preferences > Energy Saver > Uncheck Automatic Graphics Switching.

 

What happens (from my understanding) is that to conserve power, it uses the CPU to do the work of the graphics card, and of course is rediculous when running HD flash vides and such. Unchecking it will force it to always use the GPU. Which, takes a heavy chunk off that CPUs load.

 

Try it out, see for yourself. All it is is a simple box to check or uncheck if it doesnt do you any good.

 

For me - It seems to be a lot cooler now that I unchecked that.

MacBook Pro, Mac OS X (10.7), 2.66 GHz i7 (1st gen) 4 GB RAM +SSD

    My 2012 Macbook Pro Retina has always run hot, which can't be good for the long term life of the machine. I checked Activity Monitor tonight, trying to solve a different issue, and saw that Carbonite was pulling a lot of resources. I paused the auto backups, restarted the machine, and saw temps drop from 56 to 33 C. I then turned Carbonite back on, and in the space of 20 minutes the temp has climbed from 33 to 56 C. So it's a software issue with my computer. Check your Activity Monitor, as CodyDaMan suggests.

    This week I took my Macbook Pro Retina (2012) to repair for an unrelated problem and discussed the overheating issue with the service technician. He confirmed the issue with Carbonite, stating that it significantly contributes to overheating. Set Carbonite to "Low Priority" if you're using it and having problems with overheating.

     

    He also cited dust as a problem with machine overheating. Find out where the fan vents are and blow them out with compressed air. Or better yet, take the machine in for cleaning.
