Thermalright Ultra-90 Low Noise Heatsink
 

The Thermalright Ultra-90 heatsink is more compact than its brethern, but remarkably the performance differences aren't nearly as large as you might expect. The reference list above illustrates very well how most Intel heatsinks react to 150W of heat from the CPU test die... In this case though, the Thermalright Ultra-90 proved itself exceptionally!
