In this review Frostytech is testing the just released Spire Thermax II heatsink, and if you can find it for an affordable price you should find it thermally satisfying. The Thermax II (SP679S1-PCI) has four 8mm diameter direct contact heatpipes at the base, like many other heatsinks sweeping the industry right now. Spire's Thermax II heatsink stands 155mm tall, is 125mm wide and accommodates one 120mm fan that spins at 1000~2200 RPM. Weighing it at roughly 550grams, the Thermax II is compatible with both Intel socket 775 and 1366 processors.
