Best cooler for a Phenom II 720BE

well... i have a phenom iix3 720BE at 3.16 ghz pretty stable with the stock cooler. but as i have Black Edition i want to get the most out of it.

i want to push it near 4ghz keeping the temps under 75c° at full load.

i've heard about the coolermaster v8 which seems the best air cooler around according to many reviews, but i see the specs and it doesn't seems to support AM3, i've also read that AM3 has the same anchorage as AM2, but i'm not sure.

is that true? and if not which would you recommend?

also how good is the Zalman CNPS8700? they're both pretty similar in price, and it does says to support AM3


Thanks for your replies.
