The heatsink market has really run with the idea that bigger is better, with the SilverStone HE02 being no exception.  At 170mm x 130mm x 160mm (6.7 x 5.1 x 6.3") and a whopping 990g without a fan (which it does not ship with) this is one of the largest consumer heatsinks on the market.  At $66 it does cost as much as many heatsinks that do come with fans,  however it is large enough that it could be used passively on some CPUs though [H]ard|OCP's testing shows you would be wise to attach a 140mm fan if you plan on overclocking.  When they charted out the price to performance of this cooler it was obvious that this is not a worthy successor of the HE01.

"SilverStone is back with its latest air cooled heatsink unit for today's desktop processors. As far as size goes, the HE02 heatsink is mammoth. Along with the huge heatsinks we often find installation and compatibility issues. SiliverStone speaks to designing the HE02 in order to ease those pains. How well does it work though?"
