Practical Cooling Solution for Miners
The Dual 120mm to 140mm Input Fan Adapter serves cryptocurrency miners running Antminer S19 and S21 series hardware with a practical cooling upgrade solution. This adapter allows you to mount different fan sizes to optimize airflow and thermal management for your mining rig setup. By enabling compatibility between 120mm and 140mm fans, it opens upgrade paths for improved cooling performance, quieter operation, or simply utilizing available fan inventory.
Designed specifically for Antminer compatibility including S19, S19 Pro, S19j, S19 XP, T19, and S21 series models, this adapter solves real-world mounting challenges that miners face when optimizing their hardware cooling systems. The durable PLA construction withstands the thermal environment around mining equipment while providing secure fan mounting. Whether you’re upgrading for better airflow, replacing failed components with what’s available, or experimenting with cooling configurations, this adapter delivers functional value.

The Right Bracket for the Job
Anyone who has zip-tied a mismatched fan to an ASIC knows the problem: 120mm mounts, 140mm inventory, no clean way between. This adapter closes the gap with a proper bolt-up interface — larger fans running slower and quieter for the same airflow. Mount with standard fan screws and inspect the seating when you service filters. Recommended age: 14+. Not a toy. Not intended for children under 14.
Printed for the Hot Aisle
Each adapter is printed in durable PLA at Laval and dimension-checked before shipping; kept out of the hottest direct exhaust, it outlasts several fan generations. Mind PLA’s comfort zone when placing it.
