We will be installing the Scythe Mugen 5 Gaming Alliance CPU Cooler in our Ryzen system so installation will be on the AM4 socket. To prep your motherboard be sure to remove the stock retention modules on each side of the CPU socket. Keep the stock backplate in place as you’ll be mounting directly to it.
Find the AM4 spacers, which are black. Place those down on top of the holes in your motherboard. Then very carefully install the mounting bars on top of them as you see in the second picture below. The holes closest to the center are which ones you need to use for AM4.
If your fan happens to be installed to the heatsink remove it. Carefully apply the included thermal paste and place the heatsink on top of your CPU lining up the screws on the heatsink with the holes in the mounting bars. You’ll easily be able to access the front screw, but the bottom one is covered by the heatsink. Scythe has put a hole in the heatsink and using the included screwdriver you can secure the heatsink.
Now just re-install the included fan. Scythe does include an extra set of fan clips if you wanted to install a second fan. With the fan installed on the front of the heatsink we still have 100% memory clearance.
The last thing you are going to want to do is connect the 4-pin PWN cable to the CPU fan header on your motherboard and connect the standard 4-pin RGB cables to an open RGB header on your motherboard. Since our RGB header was on the bottom of our motherboard we had cables going across the board.
With everything installed and connected we are ready to power our system on. When you power your system on the lights on the top of the cooler and on the fan will light up. They look quite good and will add some extra bling to your system. We tested the lighting with ASUS’s Aura Sync and it worked no problem. Just remember if you don’t connect the 4-pin RGB cables to anything the lights won’t work at all so make sure your motherboard has a 4-pin RGB header.
