Restore Proper Cooling Performance to Your Avalon Nano 3S

The Avalon Nano 3S Replacement Fan Kit includes a complete set of three Ong Hua 12V 0.20A cooling fans specifically sized for Avalon Nano 3S Bitcoin miners. Designed to restore proper airflow and thermal performance, these replacement fans help maintain stable mining temperatures and reliable long-term operation.

Over time, cooling fans experience wear from continuous 24/7 operation, dust buildup, and the relentless reality of physics. Replacing worn or noisy fans before they fail completely helps protect your miner from overheating, thermal throttling, and unnecessary hardware stress.

Key Benefits

• Complete 3-fan replacement kit for Avalon Nano 3S
• Genuine-spec Ong Hua 12V 0.20A cooling fans
• Proper 50×50×20mm sizing for direct compatibility
• Maintains stable airflow and thermal performance

Why Replace Your Miner Fans?

Cooling fans are one of the few moving components inside ASIC mining hardware, which means they eventually wear down after prolonged operation. Weak airflow or failing fans can cause rising temperatures, unstable performance, increased noise, or even hardware shutdowns.

Replacing all three fans together helps maintain balanced airflow throughout the Canaan Avalon Nano 3S cooling system while improving operational consistency and extending miner lifespan.

An astonishingly small investment compared to replacing an overheated ASIC board.

Perfect For

• Avalon Nano 3S maintenance
• Preventative miner maintenance
• Restoring cooling performance
• Reducing fan noise from worn bearings
• Replacement for failed or damaged cooling fans

Built for Continuous Mining Operation

These Ong Hua cooling fans are designed for reliable low-voltage operation with efficient airflow suitable for continuous Bitcoin mining workloads. Their compact 50mm form factor makes them ideal for maintaining proper airflow inside the Avalon Nano 3S chassis without introducing unnecessary noise or compatibility concerns.

No sketchy modifications. No random “close enough” fans from mystery suppliers. Just proper fitment for the hardware you actually own.

Keep Your Avalon Nano 3S Running Properly

Whether you’re replacing failed fans, refreshing an aging miner, or keeping spare parts ready for future maintenance, this 3-pack replacement fan kit helps ensure your Avalon Nano 3S continues operating safely and efficiently.
