PCCOOLER F9 R120 BK 120mm 30mm case fan

High-Speed 120mm Industrial Fan

The PCCOOLER F9 R120 BK is a 120mm case fan built for heavy-duty cooling scenarios. Its 30mm thickened frame and liquid crystal polymer construction provide structural rigidity for demanding airflow requirements. A three-phase Allegro permanent magnetic synchronous motor drives the impeller. It targets builders who need concentrated airflow in restricted spaces.

Three-Stage Airflow and Pressure

Low mode delivers 63 CFM at 2.2 mmH₂O, medium reaches 82 CFM at 4.2 mmH₂O, and high pushes 114 CFM at 8.2 mmH₂O. The variable-section blade design focuses air into a tight column for radiators or dense fin stacks. At 3000 RPM the fan saturates its pressure curve, so louder operation yields diminishing returns. It suits single-fan radiator mounts but cannot replace dual-fan arrays for high-wattage loads.

Thermals, Noise and Power Draw

An NSK dual ball bearing supports the 500–3000 RPM range with a 42.7 dBA maximum noise rating at full speed. The 4-pin PWM connector allows the motherboard to scale speed automatically across the three preset bands. Anti-vibration pads decouple the 30mm frame from the chassis, reducing transmitted hum. The non-LED black finish keeps visual distraction to a minimum.
