"Thermaltake have finally produced an excellent high performance heatsink worthy of FrostyTech's Top 5 Heatsink chart. All it took was two fans, five 8mm diameter heatpipes, a 1kg mass of metal and a little concentrated effort. It's called the Thermaltake Frio heatsink. Standing 161mm tall, the 1042 gram heatsink has a modestly bulky footprint of 139x119mm, so it's best suited to full size computer cases. The Frio ships with two 120mm fans that operate at 1200-2500RPM in a push-pull configuration. The fans are non-PWM so the manufacturer has attached small fan speed controllers to each fan power cord. The heatsink is compatible with AMD socket AM2/AM3 and Intel socket 775/1156/1366 processors and can be used with one or both of the fans installed."
