Hi Dschijn,
I just installed my new setup following Techinferno wonderful guides: rMBP 13" early 2015 8Go, i7, Windows 10 and GTX970 Zotac.
I might have an issue, maybe you can help me :).
When running the last Tom Clancy's game (The Division) on my computer (Optimus working, I configured The Division to run with High Performance GPU into the NVidia 3D panel), the fan (of the mac) is running at 100% (6200 rpm), because the temp of the four cores of my CPU is between 90 and 100°C.
Is it a normal behavior?
Regards
