Glacialtech Igloo 5751 PWM Heatsink Review
 

Glacialtech's Igloo 5751 PWM heatsink installs onto Intel socket 775/1156/1366 and AMD socket AM2/AM3 processors, and stands a little over 125mm tall. Weighing in at 550grams, the heatsinks' two fans sandwich a 31mm section of aluminum cooling fins which are supported over the processor on four 6mm diameter copper heatpipes. Exhaust airflow is directed downwards towards a small extruded aluminum heatsink and adjacent motherboard components.
