This fan is in our opinion the best fan you can get for your all sky system. Directly connectable to your SkyCamOne HAT, speed control via PWM and feedback with a tachometer signal.
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 guarantee superb running smoothness and excellent long-term stability. Topped off with modular cabling, the OmniJoin™ Adaptor Set and 6 years manufacturer’s warranty, the NF-A4x20 5V PWM is a premium choice for demanding 5V applications that require PWM control and thus perfect for your all sky application.
To prevent bugs from crawling in, you should add our PVC dust filter, made to fit this particular fan.
