I have the original antec 900 still impressed I changed all the fans to non LED yate loons, except for the big 200mm one.

At the moment only the back exhaust one is one, with the front bottom one, not the one above it, and the 200mm one is turned off. My noctua push pull config is aimed at the top one, and im getting 50degC in full load under folding on a q9450 @ 3.2ghz
