Sapphire's Passively Cooled Radeon HD 7770
 

Yesterday I met with AMD's well known GPU partner Sapphire. Among their laundry list of AMD based graphics cards was this passively cooled Radeon HD 7770. The board layout had to be redesigned to accommodate the gigantic passive cooler (DRAM had to be relocated to the back of the board) but the end result is a fully clocked (1GHz core clock) Radeon HD 7770 without a single fan.
