The Alseye M120D Plus - A Detailed Review

A detailed review and installation guide to the CPU air cooler from Alseye M120D-Plus. Watch the Full Video Review on my Youtube channel below.

TLDR - It's a worthwhile cooler with the most RGB of any CPU Air Cooler I've seen or known about.


Let's see how it stacks up with my other cooler the Scythe Mugen 5.

Test Conditions:



Ambient Room Temperature

22° C

Thermal Paste

Noctua NT-H1

Noise Monitor

50 cm away from cooler/fan

Case/Test Bench

Lian Li O11-Dynamic - No Panels


AMD Ryzen 9 5900x

CPU - All Core Frequency

4.4 GHz

CPU - Voltage


CPU Package Power

150 W

From these charts, it's evident the ALSEYE M120D-Plus is doing its job in dissipating the heat and keeping the cooler cool. Although, at max RPM on the fans it does create a lot of noise. During the noise normalized tests, the cooler still manages to keep the CPU cool but at a higher temperature when compared to the Scythe Mugen 5.

  1. Lots of RGB.

  2. RGB Control via motherboard - no third party software required.

  3. Decent Performance.


  1. Poor Build Quality.

  2. Loud at Full RPM.

  3. CPU Temp OLED Display is very inaccurate.

  4. Price.

Despite these cons, the cooler has positives where it matters the most - providing decent cooling to your CPU and a lot of controllable RGB for those RGB lovers out there. One thing I forgot to mention in the Video Review is that this cooler costs on average 65 - 70 USD, which puts it against many premium air coolers from companies like Noctua, Cooler Master, etc. So the ALSEYE M120D-Plus gets my Bronze "Consider It" medal.
