Bitchin’ Sink + Noctua Fan – Solid Cooling Upgrade for Your Bitaxe

This combination is used in the Made in Germany Bitaxe Standard – and for good reason: The Bitchin’ Sink with Noctua NF-A4x20 5V PWM is not as powerful as an Ice Tower or Ice Tower Plus, but it is a noticeable improvement over the stock cooler. Compact, proven, efficient.

🧊 More aluminum, better heat dissipation

The Bitchin’ Sink is made of black anodized aluminum and offers 73% more material and 34% more surface area than the stock heatsink. It is capable of dissipating around 24W of heat – ideal for stock operation and light overclocking.

🌀 Noctua NF-A4x20 5V PWM – as quiet as it gets

The included Noctua NF-A4x20 PWM in the 5V version is compact, efficient, and exceptionally quiet. Thanks to its extra short cable, it is specially suited for the Bitaxe and integrates neatly into the setup.

• 5V PWM version – ideal for the Bitaxe
• Extra short cable for a clean setup
• As quiet as it gets – typical Noctua quality

🛠️ Made for the Bitaxe

• CNC-machined contact surface for optimal heat transfer
