Define "work". The retail hsf on the bartons is passable. if you have a higher-flow 60mm fan sitting around, and put that on there, it should do a very good job for it's size, but stock, it's just passable. They run the cpu at about the same temp the other amd retail hsfs do- 50-60*C in most computers w/reasonable ventillation. Hotter than I'm comfortable with, but supposedly cool enough.
