Noctua NF-A9 PWM (92mm/46.4 CFM/2.28 mmH2O Static Pressure/2000 RPM Max/22.8 dBA/SSO2 Bearing/No RGB/PWM) Review
Noctua NF-A9 PWM 92mm case fan, 46.4 CFM airflow, 2.28 mmH2O static pressure, 2000 RPM max, 22.8 dBA, SSO2 bearing, No RGB, PWM control. A 92mm fan for small-form-factor cases and cooler-mounting slots where a 120mm doesn't fit.
The NF-A9 PWM shrinks Noctua's A-series design down to 92mm for SFF cases, rear exhaust slots that only fit 92mm, and coolers with 92mm mounts. It keeps the SSO2 bearing, AAO frame, and 6-year warranty of its larger siblings, and its smaller diameter means it naturally builds more static pressure at a given RPM than a 120mm fan would.
Where 92mm Still Matters
Plenty of small-form-factor cases and a handful of low-profile or 92mm-native CPU coolers only accept a 92mm fan, and generic 92mm fans in that space tend to be either loud or flimsy. The NF-A9 PWM fills that gap with Noctua's usual build quality rather than forcing a compromise.
Airflow vs. Pressure Trade-off
At 92mm, the NF-A9 PWM naturally produces higher static pressure per CFM than a 120mm fan spinning at the same RPM, which makes it a reasonable choice for tight, restrictive mounting locations even though its absolute airflow number is modest next to full-size case fans.
Comparison to Alternatives
There's no other 92mm fan in this catalog to compare against directly; against a 120mm option like the Arctic P12 PWM PST, the NF-A9 PWM moves less total air but is the only realistic choice when the physical mounting space simply won't accept a 120mm frame.

Expert rating8 / 10
The go-to premium option whenever a build genuinely needs a 92mm fan instead of 120mm.
Best for
- SFF cases with 92mm-only mounts
- Coolers with 92mm fan slots
- Rear-exhaust locations too tight for 120mm
Not for
- Standard mid-tower intake/exhaust (use a 120mm or 140mm instead)
- Buyers chasing maximum total airflow
- RGB builds
FAQs
What are the key specifications of the Noctua NF-A9 PWM (92mm/46.4 CFM/2.28 mmH2O Static Pressure/2000 RPM Max/22.8 dBA/SSO2 Bearing/No RGB/PWM)?
The Noctua NF-A9 PWM (92mm/46.4 CFM/2.28 mmH2O Static Pressure/2000 RPM Max/22.8 dBA/SSO2 Bearing/No RGB/PWM) is a case fan from Noctua. Key specs: Fan Size 92, Bearing Type SSO2, Lighting No RGB, Airflow 46.4, Static Pressure 2.28.
Will the Noctua NF-A9 PWM (92mm/46.4 CFM/2.28 mmH2O Static Pressure/2000 RPM Max/22.8 dBA/SSO2 Bearing/No RGB/PWM) work with my current setup?
The Noctua NF-A9 PWM (92mm/46.4 CFM/2.28 mmH2O Static Pressure/2000 RPM Max/22.8 dBA/SSO2 Bearing/No RGB/PWM) lists Fan Size is 92. Check that against the hardware you already own before buying, since this is the field that most often decides whether a part fits.
Who is the Noctua NF-A9 PWM (92mm/46.4 CFM/2.28 mmH2O Static Pressure/2000 RPM Max/22.8 dBA/SSO2 Bearing/No RGB/PWM) best suited to?
It suits sff cases with 92mm-only mounts, coolers with 92mm fan slots, rear-exhaust locations too tight for 120mm.
What are the drawbacks of the Noctua NF-A9 PWM (92mm/46.4 CFM/2.28 mmH2O Static Pressure/2000 RPM Max/22.8 dBA/SSO2 Bearing/No RGB/PWM)?
It is a poor fit for standard mid-tower intake/exhaust (use a 120mm or 140mm instead), buyers chasing maximum total airflow, rgb builds.
