So i currently own a MBP with the 460 gpu and debating between returning for the 2015 or get the 2016 model with 450 gpu instead. The average temperature I get in bootcamp is 50-60 C. And sometimes shoots up to ~70-80c during intensive work (not gaming, FL studio). Is this lower for people with the 450 gpu?

My 15" 450 idles in the 50-60s too when connected to an external monitor (4k). This is in MacOS though, as Bootcamp throws an error at me (Cant partition drive) when I try to install Windows. It seems to drop to high 40s - low 50s when only driving one monitor via the 450 though.

using the drivers from apparently lowers the running temps by a fair few degrees. anyone willing to confirm this?

Interesting thread. I was actually considering the 460 model tho I usually go for whatever the baseline is to cut down on as much heat as possible. Not even sure the 460 is worth the upgrade over the 450 in terms of extra power when editing, but if there isn't much change in temp between the two maybe i'm overblowing this stipulation. CPU tho i'd assume gets much hotter.

The 460 is definitely worth the upgrade from the 450, if only for future proofing. The 460 runs negligibly hotter. The 2.9 GHz processor is where the heat will be.

Install MacsFanControl in Boot Camp and you can change the fan curves. I have mine set to start up at 60 degrees C and go full at 75 C based on GPU Diode temps. My idle temps - including using the drivers - with a 2.9 GHz + 460 in Boot Camp are 50-60 C for CPU and 40-60 C for GPU.

The CPU hits 85-100 C and GPU 85-90 C on full load.
