The Polaris 120 heatsink has emerged from a long time watercooling company this past week. The tower-format heatsink features the usual allotment of five 8mm diameter exposed heatpipes at the base and rippled leading edge / textured surface aluminum cooling fins. The manufacturer states that sintered copper wick heatpipes are used (good), but uses a very distributed heatpipe pattern to intersect the fin stack (odd).
The main design deviation from the standard tower-format is a large central wedge-shaped void extending from the top of the fin stack to the bottom which is said to deflect airflow to the sides of the heatsink. The upturned edges of each fin seal off the space from the fin above, rather than the void just being a large open hole punched from each aluminum fin.
The Polaris 120 heatsink stands ~150mm tall, weighs in at 850grams, costs $60 and supports Intel/AMD socket 775/1155/1156/1366/939/AM2/AM3 processors. One 800-2500RPM 120mm fan capable of moving up to 84CFM is supported, only.
