"On Frostytech's test bench today is Phanteks's PH-TC14PE (orange) heatsink. The Phanteks PH-TC14PE's five, 8mm diameter copper heatpipes fan out from a thick nickel-plated copper base plate into two 115mm tall anodized aluminum cooling towers. The fans that ship with the Phanteks PH-TC14PE (orange) are 140mm in diameter and use a nine-bladed impeller with three small notches and vertical winglets on each blade. The manufacturer describes the bearings thusly; 'updraft floating balance bearing'. Translation = sleeve bearing."
