The Igloo 7321 Silent E is a moderately compact AMD K8 heatsink, made just of extruded aluminum and an 80mm fan. The Glacialtech Igloo 7321 Silent E is rated for a maximum load of 89W, and is very quiet. The heatsink stands 71mm tall and comes with a fixed speed 80mm fan that rotates at a quiet 2000RPM. Weighing in at a light 380 grams, the Igloo 7321 Silent E is compatible with AMD socket 754/939/940/AM2 processors of 89W TDP or less. Frostytech tested the heatsink up to 125W, and the results weren't satisfactory.
