Performance – Max & Speed Percentage
Max RPM, CFM, Pressure & Power
Despite the low maximum speed, the fan’s maximum airflow is impressive, exceeding 100 CFM, a performance that other fans have to spin at over 2000 RPM to achieve. The fan’s increased thickness helps in achieving such a high airflow. The other fan with 30mm thickness in this graph is the Super Flower Megacool, which achieves the highest airflow performance. The static pressure is not high, since this fan focuses on airflow. As you can see the top fan for static pressure is the Corsair NR140HP, which is used in Corsair’s PSUs. Lastly, despite the low max speed, the fan’s power consumption is increased, at close to 3W.
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.
Hello, great review as always. Will you have a review of the Phanteks D30-140mm?
I have NO contact, at all, with Phanteks. I will see if I can find it from elsewhere.
