I increased the automatic cycle a bit in RivaTuner, it cuts in more aggressively lowering it down to 85C, though it's starting to get audible at that point.

I think I'd rather have sacrifice the 1-2% more FPS I might squeeze out of the overclock for not hearing the whine of the fan.

BTW, tested Crysis GPU Bench at stock 650/1625/950:
Avg. FPS: 35

OCed at 738/1728/972:
Avg. FPS: 38

This is at 1280x1024, High settings for everything, no AA/AF. So about an ~8% improvement from a 13% Core OC and a 6% Shader OC. I think I might just leave ram at stock to maximize timings.
