Tweaknews posted a review on the Xigmatek Thor's Hammer CPU Cooler/Heatsink

Xigmatek's Thor's Hammer is a formidable weapon in the battle against processor heat. It performed on par with the very best coolers in the comparison using a couple of inexpensive and quiet fans. The Hammer is a big cooler, particularly with two 120mm fans hanging off of it, but it delivers big performance commensurate with its bulk.
