Have you got the cpu200 block? thats a great improvement over the cpu100. I personally prefer all of the top fans blowing in one direction rather than the 1 in 2 out that it uses (at least on my model). Simple mods worth doing is getting a small 80mm radiator, thermaltake and micro - ice work well, and include that in the setup. See sig for my case, started off as a koolance.
