140 mm square-frame case fan

The Noctua NF-P14s redux-900 is a 140 mm square-frame case fan built for quiet system cooling. Its SSO bearing and 900 RPM top speed keep noise to 13.2 dB(A) while moving 83,7 m³/h of air. The 12 V 3-pin connector fits standard motherboard headers. Rated MTBF exceeds 150,000 hours.

Silent builds and radiator mounts

Suits builders who want near-silent chassis or radiator airflow with a square 140 mm frame. Not for systems that need higher static pressure at faster speeds or PWM speed control via a 4-pin header. Buyers who need variable fan curves from the motherboard should look at a PWM model.

900 RPM fixed maximum speed

The single specification that decides fit is the 900 RPM ceiling. It defines the airflow ceiling and the acoustic profile. If the thermal load demands more air than this speed delivers, a faster fan is required.

Questions about this item

Will the 140 mm square frame and 25 mm depth fit my older 140 mm mounting holes?

Yes, the 140x140x25 mm square frame matches standard 140 mm case and radiator mounts, so existing screw holes line up without adapters.

How can I confirm the fan is running at its rated 900 RPM and 13.2 dB(A) after installation?

Connect the 3-pin header to a motherboard fan connector, then check the RPM reading in BIOS or monitoring software; it should report close to 900 RPM at full voltage.

Does the box include only the fan and four screws, or are extras like anti-vibration mounts or a 4-pin adaptor provided?

The package contains the fan and four mounting screws only; anti-vibration mounts, S-ATA adaptors, Y-splitters and extension cables are sold separately.
