I have the i7 950,and it ran about 45c,so its fine,but you can put a cpu cooler on it,it doesn't even have to be a fancy one.I got a relative plain one "Antec Venom cpu cooler" and just removed the fan that came with it and i put 2 fans of cooler masters 2000rpm's on,now my cpu reads 26c,thats allot less and didn't cost allot at all.
