40mm NF-A4x20 5V PWM 5000RPM Fan

Manufacturer: Noctua. Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and an AAO frame, the NF-A4x20 5V PWM is a PWM enabled 5V variant of Noctuas highly optimised, premium quality quiet 40x20mm fan.

The custom designed NE-FD3 PWM IC that integrates Smooth Commutation Drive technology and Noctuas reference class SSO2 bearings guarantee superb running smoothness and excellent long-term stability. Topped off with modular cabling, the OmniJoin Adaptor Set and 6 years manufacturers warranty, the NF-A4x20 5V PWM is a premium choice for demanding 5V applications that require PWM control.

Being a 5V fan, the NF-A4x20 5V PWM cannot be run at 12V and will be damaged when used with typical 12V power sources such as PC motherboard fan headers.
