"The Verax Helado PWM-T heatsink is the newest uber-quiet heatsink from the German manufacturer Verax. The fan supports Pulse Width Modulation (PWM) fan speed control via a 4-pin power connector which is backwards compatible with the legacy 3-pin variety. Comprised of a nickel plated copper base block and an array of rather thick stacked aluminum fins which have also been nickel plated, the Verax Helado PWM-T is a thin tower of a heatsink. Four parallel rows of 6mm diameter "U" shaped copper heatpipes join the base of the heatsink to its's cooling fins with soldered joints."
