Review on Cooler Master ML240L RGB CPU Liquid Cooler | 240mm Radiator, Dual Chamber RGB Pump, Dual MF120R RGB Fans | RGB Lighting for AMD Ryzen/Intel Socket LGA1200/1151 by Tim Roby

Once I installed it works great. Running the Ryzen 9 3900x and under heavy gaming/streaming, the CPU never went above 55°C and idle anywhere between 38 and 43 (according to the Ryzen master program). BUT the AM4 mounts for this board are beyond annoying. The mounting bracket must be at an angle of 20-45 degrees to hook onto the motherboard bracket. And that's great until you install a second mount, where the only solution I found was to unscrew the screw completely from the head, put it on the hook, and then reinstall the screw and tighten it. This is probably one of the worst systems I can think of. The amount of movement required for the block to snap into the board mounts can cause the thermal grease to smear off the CPU, causing potential problems for those unfamiliar with it.
