Performance – Max & Speed Percentage
Max RPM, CFM, Pressure & Power
The fan’s maximum speed is low, but this doesn’t prevent it from achieving a decent airflow performance at 74 CFM. For comparison purposes, the Arctic P12 Max white needs 1331 RPM more to deliver 5 CFM more! Contrary to the RS120 MAX, the static pressure is high enough, too. These performance values are achieved at 2000 RPM max speed, which is not high for a 120mm fan. We should not forget, though, the 30mm thickness, which is 5mm more than the usual. In the graph above, only the Super Flower Megacool and the Phanteks T30-120 have the same thickness, while the Hyte FP12 is even thicker at 32mm! Lastly, the power consumption is increased given the fan’s max speed.
20 – 100% Fan Speed Percentage
Since most fan control ICs don’t apply precisely the percentage of RPM speed that you want (e.g., 50% PWM for a 2000 RPM fan should be 1000 RPM), I used to find the fan’s maximum speed and then dial directly the fan speeds that corresponded to 20%, 30%, and so on of its maximum rated speed. I decided to stop doing that. So from now on, in all of my fan evaluations, I will dial the corresponding PWM value in 10% steps to also check how accurate its fan controller is and for my noise results to align with the airflow and static pressure results from the Longwin apparatus where I don’t use RPM but PWM control for all testing.
