For installation we used a Q6600 processor, which requires the hardware for an LGA 775 installation. For this installation you need the two support brackets, which you need to place a rubber washer on each screw mount.
You then need to attach the brackets to the base of the cooler which requires two screws for each bracket. The screws are pretty small, so you may need a small screwdriver.
Once you have the support brackets attached you need to get the CPU ready, by applying the included thermal grease.
Once the grease is applied you then need to attach the CPU cooler to the motherboard, making sure you have it aligned properly. Once you do that you can attach the backplate to the rear of the motherboard and secure it by four nuts. The backplate seems to cover more surface area than most backplates, which would be appropriate to hold the massive 2.5lbs on the motherboard.
Once it’s installed you’ll notice it takes up a decent amount of case space, especially vertically. Thinner cases probably won’t house this cooler with its height of 165mm.
If you so desire, you can attach the extra fan to the cooler. If you do decide to install it, I recommend doing it prior to installing it on your motherboard and case, because it’s quite difficult once it’s installed. To attach the fan you need to attach the four rubber anti-vibration mounts. To do so you need to slide the flat portion into the openings on the four corners of the plastic mount of the CPU cooler. It might require a bit of pulling, but don’t worry, the rubber stretches pretty far.
Once you have them attached you just pull the rubber through the openings of the fan until they are secure. You also have to make sure that the fan is blowing away from the cooler to ensure that the airflow is in the proper direction.
Adding the extra fan takes up a little more surface area, obviously, than just a single fan.
