im a lil confused by your post? I had the coolermaster V8 is the N520 the same thing? anyway, i was not happy with it, looked great but just didnt work...sent it back and saved money with this cooler

and getting great performance
right now i am OC'ing my core i7 920 to core i7 965 (3.2ghz) I can go to 3.8ghz but backed it back down...
my 3dmark score is almost in the 20k mark.... not bad i must say
