In this review Frostytech will be testing a promising looking heatsink from Thermaltake called the FrioOCK. However you pronounce the name, the Thermaltake FrioOCK is a 162mm tall variation on the familiar tower heatsink with a lot of potential. The cooler weighs over a kilogram (1093grams) and comes with two 130mm fans arranged in a push-pull configuration that scale from 2100-to-1200RPM.
