oh and yea, if i can fit my Xigmatek S1283 in a Centurion 590 then you should be able to put that in there.. but, your going to have the one fan on the heat sink really close to the fan mounted to the back of the case, unless u have both fans suckin in air then it should be fine. pretty high priced heat sink.... did u look into the Xigmatek S1283??
Im waiting one the ZALMAN CNPS9900 for the LGA 1366 to be released, not long now.
If your pc case is 8 to 8.5 inches wide you'll probably be okay.
I've got the CoolerMaster HAF 932 with a large tower style cpu heatsink and a large 230mm fan on the side panel. There is plenty of room left over but that's because the case is 9 inches wide.
Thanks for the quick replies. I am still learning about OC'in and keeping my cpu cool. So far I like this the best. There is also liquid cool... but not sure what is nice yet. I do like thick hoses if I was going liquid.. any sugguestions? price limit is no more then 200.
