    Hi, since I was reading a lot about a bad thermal footprint concerning the rMBP. Here are my results while doing many hours of 3D rendering. I have the base model. Temperatures in Celsius. Fans are at max.


    By the way, when I use this Computer normal. Temperatures are much lower and I never hear the fans.

    It's a great machine and handles temperature very very well!

    What is being shown is a temp sensor located on the heatsink. The fans are controlled by the package temp of the CPU. The CPU is running much hotter than the heatsink. if your heatsink is truly at 48c... the thermal paste isn't doing a good enough job transferring the heat from the CPU die. Check your CPU temps instead, they are better at estimating CPU package temp.

    mhmm... ok thanks for that info... you are right on the money

    My CPU temp on idle is ~50C

    While on renderings it is ~90C - 100C :eek:

    I'm amazed at how naiv I was with my little thread there....

    Well, here I admit, that the thermal footprint is not that great indeed.

    It's still a great machine though :apple:
