Pros & Cons

Pros

✓ 150mm frame with 120mm mounting holes fits 105mm-spacing coolers and cases
✓ Rated 19.2 dB(A) at full 1200 RPM tilt
✓ Wide 300-1200 RPM PWM range for low idle speeds
✓ Low-Noise Adaptor caps it at 900 RPM for near-silent builds

Cons

✗ Brown and beige color scheme clashes with most themed builds
✗ 1200 RPM ceiling limits static pressure for dense radiators
✗ 150mm width can foul tall RAM or nearby case panels
✗ Not a true 140mm-hole fan, so 140mm-only mounts need adapting

Manufacturer description

The Noctua NF-A15 PWM is a 140mm premium quiet fan built around an unusual 150mm round frame that drops onto 120mm standard mounting holes at 105mm spacing. That geometry is the point: it gives you more blade area than a 120mm fan while still bolting to high-end CPU coolers like the Noctua NH-D15(S) and NH-U14S series, and to 120mm radiator and case mounts. Noctua's Flow Acceleration Channels and Advanced Acoustic Optimisation frame keep the fan to a rated 19.2 dB(A) at its 1200 RPM ceiling, and the 4-pin PWM control gives your motherboard a broad 300-1200 RPM range to work with. Drop in the…

SpecPicks Verdict

SpecPicks scored Noctua NF-A15 PWM 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

Will the NF-A15 fit my Noctua NH-D15?

Yes. The 150mm round frame uses 120mm standard mounting holes at 105mm spacing, specifically designed for high-end coolers including the NH-D15(S) and NH-U14S series.

How loud is the NF-A15 at full speed?

Noctua rates it at a maximum 19.2 dB(A) at its 1200 RPM ceiling. Using the included Low-Noise Adaptor drops the maximum to 900 RPM for quieter operation.

Does it support PWM speed control?

Yes. This is the 4-pin PWM version, giving automatic motherboard-controlled speed across a 300-1200 RPM range. A 4-pin PWM fan header is required for full control.

What comes in the box?

Anti-vibration mounts, fan screws, a Low-Noise Adaptor, an extension cable, and a y-cable that lets you run two PWM fans from a single header.

How long is this fan rated to last?

Noctua rates the NF-A15 at over 150,000 hours MTTF. Check the product listing for current warranty terms.
