"Once you get past the dark nickel plated aluminum fins that overlap on multiple levels, resembling some sort of future-fantastic piece of hardware from the Dark Knight, what really makes the Xigmatek Thor's Hammer heatsink tick are its stacked heatpipes. Yes, stacked heatpipes.

Standing 157mm tall, Xigmatek's Thor's Hammer heatsink tips the scales at 800 grams and has a rather boxy footprint of 120 x 116mm. It accomodates one or two 120mm fans that mount to the fins with special rubber vibration absorbing posts. No fans are supplied with the Xigmatek S126384 heatsink, allowing users to pick a high speed 120mm fan or ultra quiet model of their liking"
