In this review Frostytech test out a $10 heatsink from Arctic Cooling against the best and brightest (and most expensive CPU coolers out there). Does the $10 Alpine 7 Pro heatsink stack up?
"Sometimes all you really need is an inexpensive heatsink for the job, admit it. If you're building a PC with one of the new generation 65W or 45W Intel energy efficient processors, a 700gram tower of heatpipes and aluminum is a luxury CPU cooling option you may not really require. Enter the Arctic Cooling Alpine 7 Pro socket 775 Intel heatsink; a value oriented low noise extruded aluminum heatsink for Intel processors (85W or less).
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."
