60mm to 40mm Fan-to-Radiator Funnel Adapter

This purpose-built funnel adapter allows a 60mm fan to effectively drive airflow through a 40mm heatsink or radiator—ideal for enhancing the cooling performance of high-efficiency ASICs like the Bitaxe Gamma. FDM-printed in PETG, the adapter ensures focused, high-pressure airflow where it matters most.

Key Features

• Increased Static Pressure Through Radiator
  The converging funnel geometry compresses airflow, increasing static pressure at the outlet. This enhances the fan’s ability to push air through high-density fin stacks or restrictive heatsinks—critical for efficient thermal transfer.

• Improved Thermal Headroom for Bitaxe Gamma
  By ensuring consistent high-pressure airflow over the chip’s heatsink, this adapter contributes to lower operating temperatures, enabling higher clock speeds or prolonged operation at elevated hash rates without thermal throttling.

• Optimised Tapered Design
  A smooth internal taper maintains laminar airflow while minimising turbulence and backpressure. This focused air delivery maximises contact with the radiator surface area.

• Secure Fitment
  Mounting holes align with standard 60mm fan and 40mm radiator patterns, ensuring rigid, vibration-free installation.
