I ordered this, but decided to build a Core I7 system instead. So I dont need it. It compares against those thermaltake extreme cpu coolers I believe for half the price. Newegg is charging me a restocking fee so I decided to sell it here hopefully. Its $37, but not free shipping on newegg, but it also comes with a $10 mail in rebate. Im selling it for $34 shipped with $10 mail in rebate form included. Save $10 bucks give or take I never opened this. I will include invoice for rebate. Socket 775 and maybe other sockets.
