@Mega Man, In my first post I said: "I would suggest", I didn't say he should go and buy thick rads right away, it was just a suggestion
And I don't know where did you pull those charts from, but they really don't make much sense.. I don't know how that was tested, cause I've personally tested some "slim vs thick" rads, and the results were not at all like from those charts.. Obviously, the differences were not as big as if you crank the fan speeds up to a bazillion, but they were very noticeable..
And btw, I too like (and have) a good quality and loud sound (speakers), but I don't like noise.. If you know what I mean
