Fan Noctua NF-A4x20 5V PWM – All-Black Edition

Exclusively at solomining.de

Noctua fans are legendary.
Their color… well, that’s a matter of taste.

So we thought: this could look better.

In cooperation with Noctua, we created an exclusive special edition of this premium fan: the original Noctua NF-A4x20 — but completely in black.

No beige.
No brown.
Just pure all-black.

Specially optimized for Bitaxe & Nerdaxe

This version isn’t just visually unique.

We shortened the cable to the perfect length, so the fan fits Bitaxe and Nerdaxe miners exactly.

The result:

• no excess cable loops
• no ugly cable wrapping around the heatsink
• a clean, professional installation

The way it should have been from the factory (and now it is!).

Original Noctua Quality

The NF-A4x20 is considered one of the best 40 mm fans in the world.

Extremely quiet, reliable, and durable — exactly what you want for hardware that runs 24/7.

• PWM controlled for precise speed regulation
• whisper-quiet with up to just 14.9 dB(A)
• 5V operation — perfect for Bitaxe and Nerdaxe

Exclusive to solomining.de

This All-Black Edition is a special production run and available worldwide only from us.

So you’re not just getting one of the best 40 mm fans ever made —
you’re getting a version that fits your miner perfectly and looks damn good doing it.
