i have decided i really need some better cooling for my p4, its slowing down its that hot, i have narrowed it down to 2 heatsinks: the seccond on here or the second one there the zalman look better but is it worth the extra £20? i have read a good review of the arctic ice, but everyone says zalman are great! the main thing im interested in is noise levels my current fan gets very very very very loud, but both the zalman and arctic say they are very quiet! the actualy stats are in different units so i cant even compare! so which would you say is the better cooler? thanks for any replies.
