The Noctua NF-P14s redux-1500 PWM is the 140mm sibling of the redux-1700 — Noctua’s well-regarded high-performance fan in a larger format, running up to 1,500 RPM with PWM 4-pin control. The larger blade moves more air per revolution than a 120mm at the same RPM, which makes 140mm the preferred size in cases that support it. With more than 6,500 buyer reviews on Amazon and Noctua’s renowned engineering at an attainable price, it is one of the standout 140mm options. At around $18 it brings premium build to a sensible price. This Noctua NF-P14s redux-1500 PWM review covers airflow profile, acoustics, connection, longevity and value.

Size and Performance Profile (Airflow vs Pressure)
The NF-P14s redux-1500 is a 140mm Noctua fan in the same pressure-biased P-series family as the redux-1700. The 140mm size is its key strength: a 140mm fan moves more air per revolution than a 120mm at the same speed, which means the NF-P14s can deliver more cooling at a lower RPM — and lower RPM means less noise. The blade design is pressure-biased, so the fan keeps its efficiency when working through restrictive surfaces such as radiators, dense dust filters or heatsinks; it is not purely a high-airflow open-path fan. With a 1,500 RPM ceiling it has real performance headroom while staying calmer than a 1,700 RPM 120mm at equivalent settings. For cases built around 140mm support, the NF-P14s redux-1500 is one of the safest premium picks in the wider best 140mm case fans guide.
Acoustics and Noise
Acoustics are where the 140mm size really pays off. Because the NF-P14s redux-1500 moves substantial air at modest RPM, it can keep a system cool without ever spinning fast enough to draw attention to itself. Noctua’s engineering on the redux line — even though it sits below the flagship chromax and standard lines on price — already targets best-in-class acoustics, and the result is a fan that is genuinely quiet under normal load. With PWM control via the motherboard, you can tune it down to near silence at idle and let it ramp up only when the system needs more cooling. For buyers building a quiet office PC or a quiet gaming rig, that is exactly the behaviour you want. The full best quiet PC case fans guide covers slower Noctua A-series options for builds where acoustics are the absolute priority.
Connection: PWM, Daisy-Chain and Hub Support
The NF-P14s redux-1500 connects via a 4-pin PWM header, which is the standard for modern motherboards and gives precise speed control through duty-cycle modulation. PWM is meaningfully better than 3-pin DC control: it can slow the fan to a much lower minimum RPM, and it does not lose stability at low speeds. The redux line does not include PST (PWM Sharing Technology), so each NF-P14s uses its own motherboard header rather than daisy-chaining to a neighbouring fan. Modern boards typically offer enough headers for a sensible Noctua build, and for very large fan counts a fan hub can be added. Buyers who specifically want daisy-chain support should look at the ARCTIC P14 PWM PST in this guide.
Bearing Quality and Longevity
The NF-P14s redux-1500 carries Noctua’s well-known long-life bearing and is backed by the brand’s 6-year warranty — which by industry standards is exceptional. Noctua bearings are widely reported to keep running cleanly long after cheaper fans have begun to whine, click or rattle, which matters because case fans typically outlast several other PC components and are not pleasant to replace. For a fan you can install and forget about, the long-life bearing is the engineering reason Noctua commands its reputation.
Who Is the NF-P14s redux-1500 For?
The NF-P14s redux-1500 is for the builder whose case supports 140mm fan mounts and who wants Noctua’s engineering at a sensible price. It is a strong choice for front-intake or top-exhaust positions in a quiet build, for radiator duty on a 140mm AIO, and for any role where you want substantial airflow without the noise of a smaller fan working harder. It is not for buyers who want RGB lighting — the redux grey is intentionally unfussy — and not for cases limited to 120mm mounts, where the NF-P12 redux-1700 is the right pick. For 140mm Noctua quality at attainable money, the redux-1500 is excellent.
Pros and Cons
Pros: 140mm size moves more air at lower RPM than a 120mm; pressure-biased P-series design suits radiators and restrictive intakes; PWM 4-pin control; Noctua long-life bearing and 6-year warranty; large positive review base.
Cons: Grey redux livery only — no RGB; no PST daisy-chain; case must support 140mm mounts.
Is the NF-P14s redux-1500 Worth It?
At around $18 the Noctua NF-P14s redux-1500 PWM is one of the most sensible 140mm case fans on the market. It pairs the size advantage of 140mm — more air at lower RPM — with Noctua’s well-known engineering, long-life bearing and 6-year warranty, and it does so at a price that competes with much shorter-lived budget fans. The redux livery is plain and the PWM control keeps the system quiet most of the time. For builders whose cases support 140mm and who want long-term, low-noise cooling without paying for the chromax line, it earns an easy recommendation. Buyers exploring premium 140mm options should also see our best radiator fans guide.
What to Look for in a Case Fan: Quick Buyer’s Guide
Size: 140mm fans move more air per revolution than 120mm at the same RPM, delivering equivalent cooling more quietly. Where a case supports 140mm mounts, larger is generally better.
PWM vs DC: A 4-pin PWM connection lets the motherboard control fan speed precisely via duty-cycle. A 3-pin DC fan uses voltage control only, which is less precise and tends to stall at low speeds.
Airflow vs static pressure: Open-path positions want airflow-biased fans; restrictive positions behind dust filters or radiators want pressure-biased fans. Many premium fans target a balanced profile.
Bearings: Fluid Dynamic Bearings, magnetic dome bearings and Noctua’s long-life designs all outlast cheaper sleeve bearings by years. Bearing wear is the source of most fan noise as fans age.
Frequently Asked Questions
Why choose a 140mm fan over a 120mm?
A 140mm fan moves more air per revolution than a 120mm at the same RPM, which means it can deliver the same cooling at a lower speed — and lower speed means less noise. Where a case supports 140mm mounts, it is generally the better choice.
Is the Noctua NF-P14s redux-1500 PWM good for AIO radiators?
Yes. As a P-series fan it has a pressure-biased blade design engineered to push air through restrictive surfaces such as radiator fins, which is exactly what you want on an AIO.
Does the NF-P14s redux-1500 support PWM Sharing (PST)?
No. The redux line does not include PST daisy-chain. Each fan connects to its own motherboard header. Builders who want daisy-chain support should consider the ARCTIC P14 PWM PST in this guide.
Does the Noctua NF-P14s redux-1500 PWM come in black?
No — the redux version is grey only. For all-black Noctua aesthetics, look at the chromax.Black line, also covered in this guide on the NF-A14 chromax.Black.swap.
