didn't i just answer this? well anyway, most people are getting around 3.4ghz, mine tops out at 3.51
as for hintsink, tom (author Daniel Schuhmann) is comparing them with links on the main pagecpu cooler charts part onecpu cooler charts part two
one that isn't included, which disappoints me cause i wanted to see how it stood up, is the tuniq tower 120
. it keeps my overclocked 6400 (3.45ghz) to around 45 at full load. its big, but it works.
