Cooler Master MasterLiquid ML280 Mirror Review

Test results …

The test system consists of the following components …

CPU AMD Ryzen 7 2700X Processor
AMD Mainboard MSI X470 Gaming M7 AC
RAM 2x 8GB Patriot Viper DDR4 3200MHz CL16
Enclosure Corsair Crystal 680X (closed)
Ambient temperature approx. 22 °C

Review of the temperature using Prime95 in the latest version 30.3 Build 6 and the ambient temperature was 22°C. The Prime95 load was maintained until no temperature increase could be detected for 5 minutes.

MSI Dragon Center was used for fan control to set fan speeds of 25%, 50%, 75% and 100%.

The test temperatures revealed a small surprise, because no matter which fan speed is set, the temperatures are always very close to each other. The highest temperature of the AiO is 68° at 700 rpm, which is just 4° more than the lowest temperature at the maximum speed of 1350 rpm.

The MasterLiquid remains barely noticeable even at 100% fan speed, from the closed case. According to Cooler Master, the maximum noise level is 27dBA. This value is easily maintained and is thus consistently low. At only 25% and 50%, the water cooling remains so quiet that it can’t be heard out. Therefore, you can definitely set the fans to a value between 25% and 50% if you want to run the PC silently throughout. Since the temperatures between min. and max. Temp only make up a small difference, higher settings than 50% are hardly necessary.

The pump can be regulated via the mainboard’s DC control. We test here with 100% to offer comparisons with other manufacturers whose pumps are not adjustable.

RGB Effects …

Of course, the aRGB effects can also be seen in a video that can be found on our OCinside YouTube channel. Only the effects of the included controller were used!
