OCIA checks out the ThermalRight SK6+ HSF in their latest review. Here's a snip.
The install of the sink was a bit tricky. The back side clipped down onto the fingers very easily. The front side clip is set by using a small flat screwdriver. The screwdriver clip notch is not very tight and the screwdriver slipped out on my first attempt, but luckily I was prepared and had thick piece of rubber under the clip area. The bottom of the heat sink was highly polished and free of any burs or rough places and made good contact with the cpu core. I applied a small amount of silicone paste which was supplied with the unit and booted up.
