Cooler Master ML120L RGB All-In-One CPU Cooler Review

Cooler Master has recently revamped its entire line of All-In-One liquid CPU coolers, and it has specifically addressed putting a lower priced product into the market with its "Lite" series of AIOs that it says are "An easy, reliable and low noise plunge into liquid cooling." Let's see how its smallest radiator stands up to an overclocked Ryzen CPU.

Results: Temperatures

Testing will be done on our Ryzen 7 1700 processor overclocked to 3.9 GHz at 1.475 volts. This represents a very high wattage load The software used for testing will be Prime95 v29.3 with Small FFTs for the CPU load. We found Prime95 with Small FFTs load to give us repeatable results, as well as being the preferred load testing software for some major hardware manufacturers. FurMark 1.19will be stressing the GPU in the combined test, and everything will be monitored using HWiNFO 64 v5.57, and AMD's Ryzen Master. You can see our full explanation of system build-out and testing procedure outlined in this article.

We will be performing two, one hour test runs, one with Prime95 only, then a test with Prime95 and FurMark running simultaneously, inside a closed case. Temperatures from the "tdie" sensor, as well as all hardware thermocouples, and package wattage will be recorded every 5 minutes.

This may be the smallest AIO we have tested but it performed impressively considering we had an average of 151.5 watts CPU package power in the CPU test, and 156.2 watts in the combined. Temperatures stayed very consistent through both tests and the CPU never throttled down. Temperatures may have hovered a little higher than most would like during the testing, although for such a small cooler, and such a large heat load, I must say we are pleased with it's performance.

Sound Profile and Loudness

Sound testing is done from a distance of 4 feet from the side window of the case, with case fans at 60% speed which we have found to be just barely audible. With everything turned off and the room completely silent the meter registered a sound level of 39dB(A).

Sound is a bit tricky. The pump ran completely silent at a reported 2200RPM according to HwiNFO. The fan however, while not loud produced a slight buzzing noise at full speed. The fan runs at a reported 2000RPM, and at those speeds most high static pressure fans would be louder. It very well could just be our example when it comes to the slight buzz, however when it comes to airflow and airflow noise through the radiator, this fan is quite good.
