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.
