And way back in time, Apple had even factory-disabled my second NVIDIA card on my MBP because it had created heating issues in tests. So, I installed gfx, or something, to get it working. And then, predictably, major major heating issues. And it was easily solved! Apparently Apple (the rumor is Jobs ordered this, but who knows) didn't want the fans spinning too fast, which caused noise. So they governed the speed on those, too. Solved with SMC Fan Control. I wasn't too happy about being somewhat deceived by their specs for my equipment, even if they thought their intentions were "good".
