Noctua NF-P12 redux-900, Ultra Quiet Silent Fan, 3-Pin, 900 RPM (120mm, Grey)
Bottom line: The Noctua NF-P12 redux-900: 12.6 dB(A) at 900 RPM - effectively inaudible in a closed case; main trade-off: fixed 900 RPM ceiling limits peak airflow under heavy thermal load.

Pros & Cons
Pros
- ✓ 12.6 dB(A) at 900 RPM - effectively inaudible in a closed case
- ✓ Pressure-optimised blades handle radiators and dense CPU cooler fins
- ✓ Over 150,000 h MTTF rating on the 12V motor
- ✓ Grey redux colorway avoids the classic Noctua brown-and-beige
Cons
- ✗ Fixed 900 RPM ceiling limits peak airflow under heavy thermal load
- ✗ 3-pin Molex only - no PWM curve control from the motherboard
- ✗ NA-SRC10 Low-Noise Adaptor is sold separately, not bundled
- ✗ Redux line strips the accessory kit found on full-price NF-P12 models
Manufacturer description
The Noctua NF-P12 redux-900 brings the award-winning NF-P12 frame to a lower price point without touching the airflow engineering that earned it more than 100 awards from international hardware sites. This 120x120x25 mm fan spins at a fixed 900 RPM and measures 12.6 dB(A), which puts it below the noise floor of most cases once the side panel is on. Noctua's pressure-optimised blade design is the reason it works where cheap case fans stall: high static pressure lets it push air through the dense fin stacks of tower CPU coolers and the tight FPI of water cooling radiators, not just across open…
SpecPicks Verdict
SpecPicks scored Noctua NF-P12 redux-900 using a rating × review-volume × price-fit model applied to published specs and reviews across the cooling & fans category. Noctua's cooling & fans lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for cooling & fans of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
How loud is the NF-P12 redux-900 really?
Noctua rates it at 12.6 dB(A) at its full 900 RPM. That is below the audible threshold of most rooms once the fan is mounted inside a closed chassis, and the optional NA-SRC10 Low-Noise Adaptor or a reduced-voltage setup takes it lower still.
Will this fan work on a water cooling radiator?
Yes. The pressure-optimised blade design is specified for air-based CPU coolers, water cooling radiators and low-noise chassis ventilation, which is what separates it from airflow-only case fans that stall against radiator fin density.
Does it support PWM speed control?
No. This is the 3-pin Molex version running at a fixed 900 RPM, so your motherboard cannot drive a PWM curve. Speed reduction is done through voltage control or the optional NA-SRC10 Low-Noise Adaptor.
What size is it and will it fit my case?
It is a standard 120 x 120 x 25 mm fan running on 12V, so it fits any mount with 120mm spacing and 25mm of clearance. Confirm depth clearance if your chassis or cooler expects a slim 15mm fan.
How is the redux version different from the regular NF-P12?
Redux is the streamlined edition - same NF-P12 frame and blade geometry at a lower price, in grey rather than brown/beige, with the accessory bundle sold separately. Anti-vibration mounts, S-ATA adaptors, y-splitters and extension cables are all available as optional add-ons.
