We tested the airflow through our prototype module, inside a cardboard tube with some 3D printed adapters, using a UNI-T UT363 BT wind speed sensor.
Pictures of our module and airflow testing rig:
Air speed measurements were taken as the average over about 1 minute (average computed on the device).
Fan Specs and Measurements:
| Fan Type | Voltage (V) | Current Draw (A) | Power Usage (W) | Rated Static Pressure (mm H2O) | Rated Airflow (CFM) | Spec Link | Purchase Link | Air Speed Measured (m/s) |

Calculations:
The diameter of the tube that the airspeed was measured through was 30mm.
Area of circle = (30mm / 2)2 x pi = 706.86mm2
Volume of air through module = 706.86mm2 x 6.1m/s = 15.52 m3/h
Volume of air through module = 706.86mm2 x 3.8m/s = 9.67 m3/h
Results:
| Fan | Volume of air through module (m3/h) |
|---|---|
| Noctua NF-F12 iPPC 3000 | 15.52 |
| Qualtek FAD1-12025CBMW12 | 9.67 |
