Noctua NF-P14r redux-1500 PWM 140 mm case fan

140 mm Round-Frame PWM Case Fan

The Noctua NF-P14r redux-1500 PWM is a 140 mm round-frame fan built for air-based CPU coolers. It runs at up to 1500 RPM via a 4-pin PWM connector for automatic motherboard speed control. The SSO bearing and 12 V design deliver a maximum noise level of 25.8 dB(A). MTBF exceeds 150000 hours.

Suited for Tower Coolers and Radiators

This fan suits builders mounting it on round-frame compatible tower coolers or radiators where static pressure matters. The redux edition keeps the proven NF-P14r impeller at a lower cost. Buyers who need a square-frame fan for direct case mounting should look elsewhere. It also lacks bundled anti-vibration mounts or extension cables.

1500 RPM Maximum Speed

The single specification that decides fit is the 1500 RPM top speed. It sets the upper bound for airflow and static pressure while keeping noise at 25.8 dB(A). If your cooler or radiator requires a higher RPM ceiling, this model will not meet that need.
