360° View - Thermaltake ISGC-100 Heatsink Information on Frostytech's test methodology is available here.
The 92mm PWM fan spins at 600-1600RPM and draws power from a standard 4-pin motherboard fan header. Three 6mm diameter copper heatpipes extend from the base before being swaged and soldered to the aluminum fins. Each raw aluminum fin measures 0.3mm thick and is spaced 2.0mm apart. With the fan removed you can clearly see the close spacing of the fins.
The low profile Thermaltake ISGC-100 heatsink stands 70mm tall, the bottom fin is 22mm above the CPU socket. The three copper heat pipes are positioned side to side where they make contact with the processor and soldered to a 2mm thick copper plate. The footprint of this particular cooler is 121x96mm.
The copper base plate on the Thermaltake ISGC-100 measures 40x40mm in size. The three 6mm diameter heatpipes are spread out across the field of the aluminum fin array so air flow is not impeded too much.
