Virtual-Hideout posted a review on the Thermaltake Silent Boost RX K8 CPU Cooler

If Thermaltake fixes the problem area with the screws, I'd have no problem suggesting it. Better than stock cooling, quiet operation, and unique looks are good, the easy to use clip is just excellent. I'd keep an eye out for any 2nd generation RX K8 coolers.
