The NF-A9 PWM Chromax is the standard choice for high-quality 92mm fans. It has won dozens of awards and has been recommended by international hardware websites and magazines. The chromax.black.swap edition combines the NF-A9 PWM Chromax cooling with an attractive all-black design and a set of red, white, blue, green, yellow, and black anti-vibration pads that can be swapped out to match the color scheme of each build.

There are a lot of accessories, like colored cables and anti-vibration mounts, that can be bought separately to make the phone even more unique. The NF-A9 PWM chromax.black.swap comes with Noctua’s trusted premium-grade SSO2 bearing, an MTTF of more than 150,000 hours, and a 6-year warranty from the manufacturer. It is the perfect choice for users who care as much about the look of their build as they do about quality and performance.
NF-A9 PWM Chromax Design
The international press has praised Noctua’s NF-A9 dozens of times, making it a premium choice for cooling needs in the 92mm size. Tens of thousands of customers worldwide have bought it because of how well it is known to work.
NF-A9 PWM Chromax Edition
Noctua’s chromax.black.swap edition fans can be customized in color with the included swappable anti-vibration pads and anti-vibration mounts and cables that can be bought separately. It makes them perfect for people who want real high-quality fans matching popular build themes like all black, black and white, or black and red.
NF-A9 PWM Chromax Swappable anti-vibration pads in 6 colors
The NF-A9 PWM chromax.black.swap comes with eight black NA-AVP5 anti-vibration pads and four white, red, blue, green, and yellow ones. Mixing the different colors with black or making the fan all black can match the most popular color schemes for builds right out of the box. You can buy separate NA-SAVP5 sets if you want to dress both sides in the same color.
NF-A9 PWM Chromax Optional colored cables
The chromax line of fans from Noctua uses a modular cabling system with a fully sleeved black NA-EC1 30cm cable already attached. Separate white, red, blue, green, and yellow 30cm NA-EC1 cables and NA-YC1 y-cables are available for better color coordination.
NF-A9 PWM Chromax Optional colored anti-vibration mounts
Users can buy chromax line NA-SAV2 anti-vibration mounts to go with the colored anti-vibration pads with fans. These mounts make it easy, quick, and vibration-free to install fans in standard mounting holes for case fans.
NF-A9 PWM Chromax Flow Acceleration Channels
Flow Acceleration Channels are built into the suction side of the NF-A9 impeller. This change reduces the separation of the suction side flow by speeding up the airflow in the most important parts of the outer blades. It makes the fan more efficient and quieter.
NF-A9 PWM Chromax AAO frame
Noctua’s AAO (Advanced Acoustic Optimisation) frames include anti-vibration pads and the company’s own Stepped Inlet Design and Inner Surface Microstructures, both improving the fan’s performance and noise efficiency.
NF-A9 PWM Chromax Stepped Inlet Design
The Stepped Inlet Design from Noctua adds turbulence to the intake to make the change from laminar flow to turbulent flow easier. It reduces tonal intake noise, improves flow attachment, and increases suction capacity, especially in places with limited space.
NF-A9 PWM Chromax Inner Surface Microstructures
When the tips of the fan blades go through the boundary layer made by the Inner Surface Microstructures, flow separation from the suction side of the blades is greatly reduced. It reduces blade passing noise and improves airflow and pressure efficiency.
NF-A9 PWM Chromax SSO2 Bearing
The NF-A9 has the second generation of Noctua’s well-known and time-tested SSO bearing, which has improved further. With SSO2, the back magnet is moved closer to the axis, which makes it even more stable, accurate, and durable.
NF-A9 PWM Chromax Custom-designed PWM IC with SCD
The NF-A9 PWM uses Noctua’s new, custom-designed NE-FD1 PWM IC, which has Smooth Commutation Drive (SCD) technology built in. It allows for fully automatic PWM speed control. By making torque impulses smoother, SCD quiets PWM switching noises and makes the fan quieter at low speeds.
NF-A9 PWM Chromax Stops at 0% PWM
The fan will stop when the motherboard or PWM fan controller sets the fan’s duty cycle to 0%. It makes it perfect for building semi-passive cooling systems where the fans turn off when the temperature is right, letting the system run silently at idle.
NF-A9 PWM Chromax 6-year manufacturer’s warranty
Noctua fans are known for being of the highest quality and lasting very long. The NF-A9, like all Noctua fans, has an MTTF rating of more than 150.000 hours and comes with a full 6-year warranty from the company.
