Accessories and Documentation
The four wire fan mounts you see here are left floating free inside of the hardware box. As for the universal back plate, it was shipped inside of a bag to keep the paint in good shape. There are already Intel isolation pads on this plate, but for AMD usage you need to get some pads out of the rest of the hardware.
There are studs that run through the back plate and up thorough the motherboard. Once you add some risers, you can then add either the pair of Intel or AMD top brackets that are held in place with thumbscrews. Once those are in, you can attach the cross-bar to the studs to mount the cooler to the motherboard.
Starting at top left, you are given four LGA2011 mounting screws, some thermal paste, and the four studs to use with the back plate. The bag of screws doesn't go to this cooler, but are included with the four black spacers, an LGA775 plate spacer, eight fan isolation pads, four thumbscrews, and a sheet of clear plastic pads to use on the AMD side of the back plate.
The included fan is the HA1220H12SA-Z, which is 120mm by 20mm. This nine blade fan that is solid black in color is PWM controllable as it is powered via the 4-pin fan connection on its left.
Here again we get to see the manual. Things are kept very simple on the outside and on the inside.
As you can see, SilverStone must use the same kits for all of the Nitrogon series coolers, and it explains the extra screws. It also explains why in the six simple steps to installing the CPU cooler for both AMD and Intel, you find renderings with the instructions of tower coolers and other oddities. So keep in mind that these are general installation instructions, and it may differ slightly from the images to your actual cooler.
