The Coolage Freezer Orb heatsink is designed for Intel Core 2 Duo processors, and as with most heatsinks seeking to banish the stock Intel heatsink from the PC, it comes equipped with a Pulse Width Modulation (PWM) fan. The 95mm fan spins at speeds of 1000-2800RPM, so under most circumstances this heatsink operates quietly enough to go unnoticed. A full copper version of the FO-Z924AL is also in the works, according to Coolage. The Freezer Orb F0-Z924AL heatsink is nice and squat, with the business end of it measuring 42mm tall. The aluminum fins aren't nickel plated, so heatpipe-to-aluminum joints are swaged and not soldered. The four 6mm diameter heatpipes are soldered to the copper base however.
