Mikhailtech take a look at Akasa's AK-688 Black Knight copper heatsink with included 3.5" fan controller/USB hub.

The clips used for attaching the heatsinks generally follow Intel's reference design, but with a twist. The "legs" can bend outward so you can place the fan fixture on top of the cooler and line up the hooks one by one without a problem. This is a very versatile and worry-free approach. The latches on the clips are a little stiff but after a few bends they loosen up, so no complaint there.Read more
