The Alpine 7 Pro retails for less than $15CDN ($15USD), and comes with a pre-installed patch of thermal compound. This is a no-frills heatsink, but it makes some concessions towards lower noise production. In tradition Arctic Cooling fashion, the Alpine 7 Pro is equipped with a fan suspended on rubber shock absorbing posts. The fan is suspended on Fluid Dynamic Bearings, is PWM controlled and rotates from a whisper quiet 500RPM to a moderately audible 2000RPM. Weighing it a 480 grams the Alpine 7 Pro is entirely aluminum, and covered by a 6 year warranty. The real question is whether the Alpine 7 Pro can stand up acoustically, and thermally.
