Noctua NF-A9x14 92mm Slim Chromax Black Swap PWM Fan 2500 RPM SSO2 Bearing – NF-A9x14 PWM CH.BK.S

Award-Winning NF-A9x14 Design and Proven Efficiency

Having received dozens of recommendations and accolades from the international tech press, Noctua’s NF-A9x14 has established itself as the definitive premium choice for slim 92mm cooling needs. Its renowned aerodynamic efficiency and dependable engineering have convinced tens of thousands of customers worldwide, making it a trusted cornerstone for high-performance compact builds, HTPCs, and space-constrained server environments.

Chromax.Black.Swap Edition for Ultimate Customisation

Maximising aesthetic freedom and colour coordination, the NF-A9x14 chromax.black.swap edition allows enthusiasts to fully tailor their cooling setup. By utilising the included self-adhesive anti-vibration pads alongside optional coloured cables, users can effortlessly match their fan to popular build themes such as sleek all-black, striking black and white, or aggressive black and red configurations without compromising on acoustic or thermal performance.

Comprehensive Colour-Customisation with Swappable Anti-Vibration Pads

The fan ships equipped with eight swappable, self-adhesive anti-vibration pads across six distinct colourways—black, white, red, blue, green, and yellow. This modular padding system empowers builders to fine-tune every visual detail of their interior rig, ensuring seamless integration with motherboards, graphics cards, and chassis lighting schemes.

Modular Cabling System and Optional Coloured Cables

Engineered around Noctua’s sophisticated chromax line modular cabling architecture, the fan comes pre-fitted with a fully sleeved, premium black NA-EC1 30cm extension cable. For builders pursuing advanced colour synchronisation, individual white, red, blue, green, and yellow 30cm NA-EC1 cables, as well as matching NA-YC1 y-cables, are readily available separately to complete clean cable management routines.

Ultra-Slim 14mm Low Profile Form Factor

Measuring a mere 14mm in thickness, the NF-A9x14 is drastically slimmer than standard 92x25mm cooling fans. This ultra-compact form factor makes it the ultimate solution for applications where standard fans would fail due to tight clearance limitations, such as low-profile CPU coolers in compact Small Form Factor (SFF) chassis, Home Theater PCs (HTPCs), or dense rackmount server enclosures.

Advanced Aerodynamics with Flow Acceleration Channels

The meticulously crafted NF-A9x14 impeller features suction-side Flow Acceleration Channels. By accelerating airflow across critical outer blade regions, this innovative engineering technique significantly reduces suction-side flow separation, resulting in enhanced aerodynamic efficiency, higher pressure delivery, and a marked reduction in vortex-induced turbulence noise.

Advanced Acoustic Optimisation (AAO) Frame Architecture

Noctua’s proprietary AAO frames integrate pre-fitted anti-vibration pads alongside advanced structural innovations including Stepped Inlet Design and Inner Surface Microstructures. These cutting-edge features work in synergy to push the boundaries of psychoacoustic performance, maximising the airflow-to-noise ratio under demanding operational loads.

Stepped Inlet Design and Inner Surface Microstructures

The unique Stepped Inlet Design introduces controlled turbulence to the incoming airflow, facilitating a smooth transition from laminar to turbulent flow to suppress tonal intake noise and boost suction capacity in restricted spaces. Complementing this, Inner Surface Microstructures allow blade tips to cleanly slice through boundary layers, virtually eliminating blade-passing noise while boosting overall pressure and airflow efficiency.

Refined SSO2 Bearing Technology

Equipped with the second generation of Noctua’s acclaimed, time-tested SSO bearing system, the NF-A9x14 features an optimised rear magnet positioned closer to the axis. This precise geometric placement delivers exceptional rotor stabilisation, rotational precision, and long-term mechanical durability.

Custom-Designed PWM IC with Smooth Commutation Drive (SCD)

Supporting fully automated PWM speed control from 600 RPM up to 2500 RPM, the fan incorporates Noctua’s advanced custom-designed NE-FD1 PWM integrated circuit. Featuring Smooth Commutation Drive technology, it delivers smoother torque impulses that effectively suppress electrical PWM switching noises, ensuring remarkably quiet operation at lower rotational speeds.

0% PWM Stop Capability for Semi-Passive Silencing

When configured by the motherboard or external PWM fan controller to a 0% PWM duty cycle, the NF-A9x14 completely halts rotation. This capability enables enthusiasts to engineer sophisticated semi-passive cooling profiles that automatically deactivate fans during idle or low-load states, achieving absolute silence when system thermal headroom permits.

Uncompromised Reliability and 6-Year Manufacturer’s Warranty

Built to uncompromising quality standards, the NF-A9x14 boasts an exceptional Mean Time To Failure (MTTF) rating exceeding 150,000 hours. Backed by a comprehensive 6-year manufacturer’s warranty, this fan provides ultimate peace of mind and long-lasting reliability for professional workstations and enthusiast gaming rigs alike.
