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.
Highlights:
* Frame technology: Advanced Acoustic Optimisation (AAO).
* RPM: 5000.
* CFM: 5.5.
* dBA: 14.9.
* Fan width: 40mm.
* Fan depth: 20mm.
* Bearing type: SSO2.
* Connector: 4Pin.
* Warranty: 6 years.
