140 mm static-pressure fan

The NZXT RF-P14SF-B2 is a single 140 mm case fan built for static-pressure tasks such as radiators and dense heatsinks. Its fluid dynamic bearing and chamfered frame are designed to push air through restriction while keeping noise low. The non-LED black finish suits builds that prefer a clean, unlit look. PWM control allows the motherboard to adjust speed automatically based on temperature.

93.2 CFM at 1700 RPM with 4.45 mm H2O

At full speed the fan moves 93.2 CFM and develops 4.45 mm H2O of pressure, giving it headroom for most dual-radiator or thick-heatsink setups. The 500 RPM floor lets the curve drop to near-silent operation during light loads. Beyond 1700 RPM the fan cannot spin faster, so extremely restrictive loops or very high heat loads may need additional airflow. The +/- 200 RPM tolerance means actual peak speed can vary slightly between units.

30 dBA peak noise with fluid dynamic bearing

The manufacturer rates maximum noise at 30 dBA, which is generally inaudible inside a closed case under typical system load. Fluid dynamic bearing construction reduces friction and contributes to long-term acoustic consistency. Power draw is handled through a standard 4-pin PWM connector, so no separate controller or adapter is required. The 25 mm thickness fits standard 140 mm mounting points without clearance issues.

Questions about this item

Will the 140mm frame fit the same mounting holes as my current 140mm fans?

Yes, the 140 x 140 x 25 mm dimensions match the standard 140mm mounting pattern used by most cases and radiators.

How can I confirm the fan is running within its 500-1700 RPM range after installation?

Connect the 4-pin PWM header to your motherboard and monitor the speed in BIOS or fan-control software; it should report between 500 and 1700 RPM under load.

Does the box include mounting screws or do I need to buy them separately?

The fan ships with four mounting screws in the box, so no separate purchase is required for standard case or radiator installation.
