Compact yet powerful. Quiet yet effective.
Designed with Noctua's legendary engineering, the NF-A4x20 5V PWM fan delivers outstanding cooling performance despite its small size.
Perfection is in the Details
Thanks to Noctua's innovative PWM motor technology , Bitaxe provides complete silence while spinning at the speed you need to cool your ASIC-powered hardware.
Minimal vibration, long-lasting durability and ultra-low noise levels – all in one.
Whether for high-performance small systems or quietly running media devices, the NF-A4x20 redefines the boundaries in the cooling class of 40mm fan ASIC processors.
With its aerodynamic design, this fan provides smooth air flow, offering maximum cooling performance with minimum noise. Equipped with Noctua's patented AAO frame technology , it optimizes air flow in the most efficient way thanks to Flow Acceleration Channels .
The long-life SSO2 bearing technology brings Noctua fans to an unparalleled level of reliability and durability. The NF-A4x20, a durable and powerful solution for silent cooling, offers a product you can use with confidence with its 150,000-hour operating life.
Small in size but big in performance.
Noctua NF-A4x20 5V PWM is designed to operate reliably in even the most demanding hardware environments such as Bitcoin ASIC mining.
It makes the difference in quality cooling and refrigeration felt everywhere, from compact systems to industrial applications.
Noctua Fan Quality
Noctua is a brand that always aims for perfection. NF-A4x20 5V PWM takes cooling performance to the highest level in Bitcoin mining hardware with fan technology.
Noctua NF-A4x20 5v-4-Pin Bitaxe is the ideal case for those looking for not only cooling but also a perfect silence experience for their ASIC processors in their hardware.
5V-4 Pin PWM Version
A large number of devices such as networking, storage solutions, Bitcoin Bitaxe miner ASIC processors use 5-volt 40 mm fans with PWM speed control.
With the same operating voltage, PWM support and compatibility with special fan connectors, the NF-A4x20 5V PWM is an ideal fan system to replace standard cheap Chinese fans, noisy, high-noise or damaged, broken, processor cooling fans that have lost their cooling feature, and to strengthen the cooling system of your hardware.
