The cooling abilites of the Swifttech series shine much better when you crank up clockspeed/voltage/heat. The copper base on many fairly high end coolers keeps the core at close to the same temperature as more expensive ones, but once you start getting high heat outputs, the extra mass of the Swifttechs' shines through. For example, on a one GHz T-Bird, the Swifttech MC-462 and the SK-6 preform relatively equally, but at 1.4GHz the difference is much more pronounced.
