FrostyTech posted a review on the Glacialtech Igloo 7312 Silent E Heatsink
The Igloo 7312 Silent E is a moderately compact AMD K8 heatsink, made just of extruded aluminum and an 80mm fan. The Glacialtech Igloo 7312 Silent E is rated for a maximum load of 89W, and is very quiet. Glacialtech's Igloo 7312 Silent E heatsink stands just 70mm tall and comes with a fixed speed 80mm fan that rotates at a quiet 2000RPM. Weighing in at a light 371 grams, the Igloo 7312 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 just satisfactory.Glacialtech Igloo 7312 Silent E Heatsink Review
