I fresh installed x64 7 Pro yesterday and after running a heavy load (GTA IV) and exiting the game, I saw my temps were in the high 70s for all my cores. After closing the game and waiting a while, Core Temp still reported temps at around 60 C, with some spikes into the 70s.

Before this, I was running x86 RC 7100 and idle temps were around 35-45 C, with load temps at around 60 C.

So I reinstalled Windows 7 Pro, this time the 32-bit version and I saw that the temps were once again much lower.

My question is, why did this occur? I would think that x64 is much more efficient, but temps were hot.

My system:
CPU: Core i5-750 @ 2.66 GHz, stock cooling
RAM: 4GB DDR3 Ripjaws
Video Card: ATi Radeon HD4890
HD: 320 GB Seagate, 1.5 TB Seagate, two external HDs.
