Performance and Operation
In evaluating the Cooler Master MasterLiquid ML240R RGB, we place emphasis on its ability to dissipate heat efficiently, maintain low noise levels, and the adaptability of its PWM control.
Cooling Efficiency
Heat Dissipation: The centerpiece of the ML240R RGB’s performance is its radiator’s capacity for heat dissipation. During our tests, the 240mm radiator, coupled with the 120mm fans, facilitated a swift removal of heat away from the CPU. Even under heavy loads, the temperature did not escalate past our comfort zone, confirming the cooler’s efficiency in maintaining CPU health.
At idle temperatures, the ML240R RGB demonstrated commendable control over heat, ensuring the CPU’s baseline temperature remained consistently low. Our measurements assure that for general browsing and low-impact tasks, this cooler keeps things cooler than what we’ve seen in some competitors.
Noise Levels
The noise level output from the ML240R RGB is an important factor, especially for users who favor a quiet operating environment.
| Fan Speed | Decibel Reading | Operational Mode |
| 2000 RPM +/- 10% | Measured under 30dB | High Performance |
| Idle to Moderate | Measured around 25dB | Silent Operation |
Our findings reflect that the fans operate within acceptable noise levels, providing an undisturbed work environment. The fans reached a peak RPM a little above their advertised 2000, yet their noise output remained beneath the noise level of a quiet bedroom at night.
PWM Control
The ML240R RGB’s PWM fans give us precise control over the fan speed. Our ability to adjust fan speed according to the system’s cooling needs is seamless, ranging from quiet operations during light tasks to more robust air flow during CPU-intensive processes.
PWM Range: A wide RPM range ensures that the cooling system’s performance is adaptable to various stress situations. These fans respond dynamically to CPU temperature changes, providing increased air flow when required without a manual prompt.
Through our experience, the ML240R RGB’s operation struck a balance between aggressive cooling when pressing the CPU to its limits and maintaining silence during periods of low demand – a testament to the efficiency of its PWM control system.
