FrostyTech posted a review on the Glacialtech Igloo 5610 Plus Silent Heatsink

The Igloo 5610 Plus Silent ships with two 92mm fans, each spinning at
1200RPM but arranged in a push-pull fashion. A pre-applied patch of shinetsu thermal compound on the base of the heatsink means it's ready to be used out of the box. Given the relatively compact height of the Igloo 5610 Plus Silent, it should fit into most compact PC cases easily enough.
