Firstly we installed the Xigmatek back plate using the AM3 holes.
The backplate was secured using the threaded spacers which need tightened by hand.
Next, we have to install the AMD brackets which are screwed down tight with the thumbscrews. Again, there is no option to use a screwdriver.
Next, we add the thermal paste and install the heatsink. The installation procedure incorporates a large bar that presses down the heatsink and screws onto the AMD brackets across the middle. This time you can use a screwdriver or even the supplied spanner to tighten the two screws.
Once mounted the heatsink is secure, and is easy to remove. As you can see there is plenty of space next to the memory slots.
Once the heatsink is installed we then look at installing the fan.
The fan mounts clip onto the heatsink via rubber grommets, but they don’t align easily. These force some of the fins part when mounted also. They are of course designed to reduce vibration, but I think I would prefer a metal clip with a few rubber strips.
