The NF-A4x10 is a highly optimized quieter 40x10mm fan of premium quality, which draws on pioneering aerodynamic design measures such as Flow Acceleration Channels and Noctua's AAO-frame system. The PWM version uses Noctua's specially designed NE-FD1 IC IC for fully automatic speed control via 4-pin connectors and comes with a low-noise adapter and a OmniJoin Adapter Set Adapter set for operation on proprietary connectors. His superb running smoothness, the SSO2 reference-class warehouse and Noctua's proven premium quality make the NF-A4x10 PWM to a fine choice for the highest demands.
