State-of-the-art quiet cooling performance for CPU coolers in a sleek all-black design: The chromax.black version of the award-winning NF-A14x25r G2 round-frame 140mm fan. Succeeding the iconic NF-A15, the NF-A14x25r G2 has quickly established itself as a new benchmark for premium quality quiet round-frame 140x25mm fans. Its advanced aerodynamic engineering featuring a novel Progressive Bend impeller design with Centrifugal Turbulator hub, winglets and a record tight tip clearance of only 0.7mm enables the G2 model to provide a significant boost in performance-to-noise efficiency over its renowned predecessor. At the same time, its etaPERF motor with SupraTorque can leverage extra torque headroom when required, which makes the NF-A14x25r G2 an ideal upgrade for NH-D15, NH-D15S and NH-U14S heatsinks. The chromax.black edition combines the NF-A14x25r G2s Sterrox liquid-crystal polymer impeller, comprehensive feature set and breakthrough quiet cooling proficiency with an attractive black design. Topped off with Noctuas trusted premium-grade SSO2 bearing, more than 150,000 hours MTTF and a 6-year manufacturers warranty, the NF-A14x25r G2 PWM chromax.black is the perfect choice for users who are looking for cutting-edge quality, quietness and performance in an all-black style.

The Noctua NF-A14x25r G2 PWM chromax.black is a quiet, round-frame 140mm PC fan with PWM speed control, suited to builders upgrading compatible 14cm CPU coolers such as the NH-D15, NH-D15S, or NH-U14S.
Recommended For
- Owners of compatible round-frame CPU coolers such as the NH-D15, NH-D15S, or NH-U14S who want a quieter replacement fan while maintaining strong cooling under CPU load.
- Quiet-build owners who want one fan to handle demanding cooling and then slow down for less audible operation; independent testing found strong cooling efficiency relative to noise and a broad speed range.
- Builders replacing fans on a radiator or other mount with 105 × 105 mm hole spacing who have room for a 140 mm fan frame and want to use a 140 mm fan in that mounting pattern.
- PC builders who prefer an all-black fan and need PWM speed control for a CPU cooler, radiator, or case airflow setup; the chromax.black version keeps the G2 cooling design without Noctua’s usual brown-and-beige appearance.
Real-World Use Scenarios
- Replacing a worn or noisy fan on a compatible tower CPU cooler, such as a supported NH-D15, NH-D15S, or NH-U14S, can restore airflow while keeping fan noise more subdued at lower speeds.
- Upgrading the fan on an older NH-D15 or NH-D15S can help users maintain CPU cooling with a quieter fan curve; check the cooler’s clip and fan compatibility before buying.
- Adding a second fan to a compatible dual-tower air cooler can support push-pull airflow through the heatsink, which is useful when tuning cooling for sustained CPU-heavy workloads.
- Building a low-noise PC for everyday work or gaming, users can set a motherboard PWM curve to keep the fan slower during light use and increase cooling as CPU temperatures rise.
- Matching a black-themed PC build while replacing a compatible cooler fan gives the system a more uniform appearance without changing the cooler’s basic setup.
