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 Noctua's highly optimised, premium quality quiet 40x20mm fan. The custom designed NE-FD3 PWM IC that integrates Smooth Commutation Drive technology and Noctua's reference class SSO2 bearings assure superb running smoothness and excellent long-term stability. Topped off with modular cabling and the OmniJoin Adaptor Set, 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.
