Most XP-M's will OC to 3200+ speeds with the stock cooler and little to no increase in voltage, so yes, that should work great.
I have heard good things about that heat sink in the lower end arena.
Suggestion, though, don't use the Cooler Master LED fan; the things are kinda noisy. (I have one, it's the main source of noise in my comp now.) Try an Antec 80mm Pro fan instead, about the same airflow and significantly quieter.
