Noctua 40mm NF-A4x20-5V 5000RPM Fan

Manufacture # Noctua | Model # NF-A4x20-5V

Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua’s AAO frame, the NF-A4x20 5V is a dedicated 5V version of Noctua’s highly optimised, premium quality quiet 40x20mm fan. Smooth Commutation Drive technology and Noctua’s reference class SSO2 bearings guarantee superb running smoothness and excellent long-term stability.

Features:

• Compared to Noctua’s award-winning NF-A4x10, the NF-A4x20 is twice as thick, which allows for increased static pressure performance and makes the NF-A4x20 ideal for demanding applications with high flow resistance.
• The NF-A4x20 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise.
• The NF-A4x20 features the further optimised second generation of Noctua's renowned, time-tested SSO bearing.
• Many devices featuring 40mm fans use proprietary fan headers, so the NF-A4x20 comes with Noctua's OmniJoin™ adaptor set.
