i think the 6cu+ is your best bet..
the dragon might crush the core, the zalman doesnt cool well, and the 6cu+ cools good, and is a generic clip design, so not likely to crush
i have the 6cu, because i would not be able to stand the volume of the cu+...
2500 rpm difference between the cu and the cu+
and to tell you the truth, the cu+ only gets like 2 degrees difference...at least here at my house...on two identical machines...
both k7s5a's, both athlon 900's...
mine ran 1 degree C under my friends when he was using the cu+...
maybe some people have better results with it...but i havent seen much differecne..
my temps are pretty good..
when my 120mm fan is not on, i run at 48* full load...
but with the 120 on, i get like 46* full load.
and even then it is still quieter than my friends comp, and a lower temp!
so, i would personally go for the cu, just to save your hearing...
but the cu+ is good too...
also, see if you can get your hands on a volcano 7....supposedly pretty cheap, and cools better than cu+, and is quieter...(80mm fan on it)
