Virtual-Hideout checked out the Thermalright Ultra-90-K8 Heatsink
I'm not going to say I'm highly impressed with this cooler, but I'm not disappointed with it either. The Thermalright Ultra-90 performs just like all the other heat pipe coolers in its size range. The temps are only 1-2C difference under idle and load conditions.Thermalright Ultra-90-K8 Heatsink Review
