The installation of the Dark Rock Advanced C1 cooler is not very complex but it requires tools and some time. To begin with, you need to screw the correct retention brackets for your CPU slot onto the base of the cooler.
You will not have to remove your motherboard from your case if the motherboard tray is cut open behind the CPU area but it might prove to be difficult for one person alone to hold both the backplate and the cooler while securing the cooler by screwing it down. Unfortunately the universal backplate cannot be secured on the motherboard prior to securing the cooler; both parts are being held in place by the same screws.
The Dark Rock Advanced C1 cooler looks surprisingly compact when installed on a motherboard; however it can still cause problems with tall RAM modules installed on the first two RAM slots if the slots are close to the CPU area.
