Well this is probably the most badass heatsink on the market... GruntvillE
at the Thermalright SLK900U.
One of the other things that make the SLK-900U unique is that
you can mount just about any type of fan on it, from a 70mm to 92mm. The stock
fan that ThermalRight suggests is a Delta 92mm fan that moves an impressive
110.18CFM at a noisy 55dBA. However, most vendors on the web sell the unit without
a fan so you can pick and choose which one suits your needs. For this review
we will be using a ThermalTake Smart Case Fan-2 80mm fan which at full speed
runs at 4800RPM, 48dBA, and moves 75.7CFM.
