be quiet! Pure Rock 3
3. Installation
Installing the CPU cooler requires several steps.you can read the included manual and some basic steps are mentioned below:
1. To permit mounting of the cooler please remove both the plastic retainers of the AMD retention module. The factory fitted backplate affixed to the rear side of the motherboard will be needed for subsequent installation of the cooler.
2. Place the 4x AMD spacer nuts onto the backplate bolts protruding through the front side and affix both short AMD mounting brackets with the AMD backplate screws.
3. Place the CPU block centrally over the short AMD mounting brackets, such that these allow the CPU block to be screwed down. For this, you can use a normal crosshead screwdriver. Next, connect the 4pin PWM fan to the CPU 4pin header at the motherboard.
Here is how the product would look alike in an installed system.
