Low-FPI radiators need fans that deliver strong airflow, while high-FPI radiators demand higher static pressure to push air through dense fins.
Thickness also affects airflow path, so thicker radiators require fans with greater static pressure.
Remember, static pressure (measured in mmH₂O) reflects a fan’s ability to overcome resistance, not just its airflow (CFM).
Here’s a quick guide:
| Radiator FPI | Thickness (mm) | Recommended Static Pressure (mmH₂O) |
|---|---|---|
| Low (6-8) | Thin (<30) | 1.5 – 2.0 |
| Medium (10-12) | Medium (30-50) | 2.0 – 2.5 |
| High (14-16) | Thick (>50) | 2.5 – 3.0 |
Match these to optimize cooling.
