"Attached to the top of the copper base which makes contact with the CPU is a small nickel-plated aluminium heatsink, which is itself linked to the four copper heatpipes to help provide the maximum possible heat transfer away from the CPU itself.

These heatpipes are, of course, attached to a large number of aluminium fins, which is angled at what initially seems like an odd position, but is supposedly the optimum angle for heat transfer, particularly if your chassis has a rear fan to exhaust hot air out of. Atop those fins is the Silent Spirit's cooling fan itself, which is fitted with rubber fan mounts to stop vibration noise and keep the fan running as quietly as possible."
