The Glacialtech F101 PWM heatsink is built around a simple concept; use the space over the motherboard chipset for extra cooling fins. The result is a collection of copper and aluminum connected together by five sintered wick copper heatpipes. The 6mm diameter heatpipes distribute heat across a standard tower heatsink format, save for an extension that juts 35mm off to one side.
