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. Affix the fans to the radiator with the fan mounting screws. We recommend installation in a push configuration. With the fans facing towards the model name on the radiator, mount them on the hose side.

4. Affixing the radiator to the case. That step depending your case may vary. The main idea is to keep the radiator above the CPU level to keep air at the top.

5. Use the build-in 3 in 1 PWM cable and connect it to your CPU 4pin motherboard connector.

6. Remove the protective foil from the underside of the cooler. Spread the thermal paste on the surface of the CPU. The amount supplied is sufficient for one or two applications.

7. 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 pump to the PUMP 4pin header CPU fan.

8. Refilling the system: Top up the system after about two years of use. In order to do this, first detach the radiator from the case. The filling port is on the opposite end of the hoses. Open this as well as the bottle with cooling fluid. Rotate the bottle into the filling port. Hold the radiator so that the filling port is at the highest level with the bottle upended over it. Then lightly squeeze the bottle. Repeat this until no further air bubbles appear in the bottle.
