It's really all a function of how much voltage the chip requires to run stable @ 200 FSB. If you're able to hit 200 FSB with the default voltage (1.65v), then the stock AMD HSF should be able to keep the temps down around a reasonable level.
However, if you have to bump the voltage up to 1.8v or 1.85v for stability, then your temps may get a little high for your liking.
Eithe way, just try it and see....
