* Minimal air resistance between fins allowing best balance between noise and performance in range of 800-1200RPM. For all out performance, fan RPM at 1600 or above is recommended. * Heatpipes are lined up in a straight line to prevent air back draft allowing air to easily pass through the heatsink body. * Wide fins with mathematically calculated thickness to maximize best air-to-surface cooling rate. * Uniquely designed, easy-to-install socket 775 and 1366 retention mechanism to increase cooling ability. * Includes easy-to-apply high grade thermal compound, a perfect sidekick to all Prolimatech heatsinks.
