Routine Maintenance Checklist

1. Regular Cleaning: Dust and debris can accumulate within the miner’s internal components over time， potentially impacting cooling efficiency and leading to performance degradation. Establish a regular cleaning schedule， using compressed air to gently remove any buildup from the heatsinks， fans， and other critical areas.
2. Fan Inspection: The M66S+ relies on its cooling fans to maintain optimal operating temperatures. Periodically inspect the fans for any signs of wear or damage， such as unusual noises or decreased airflow. Promptly replace any faulty fans to maintain the miner’s thermal management capabilities.
3. Thermal Paste Reapplication: Over time， the thermal paste applied between the ASIC chips and heatsinks can degrade， reducing heat transfer efficiency. It’s recommended to reapply high-quality thermal paste every 6-12 months to ensure optimal heat dissipation and prevent thermal throttling.
4. Firmware Updates: Regularly check for and install any available firmware updates from Whatsminer. These updates may include performance enhancements， bug fixes， and security improvements， helping to keep your miners operating at their best.
5. Power Supply Inspection: Examine the miner’s power supply connections and cabling for any signs of wear or damage. Ensure that all power connections are secure and free of corrosion to maintain stable power delivery to the system.
6. Network Connectivity Verification: Test the Ethernet connection to your M66S+ miners， checking for any issues with network stability or data transfer. Promptly address any connectivity problems to ensure seamless integration with your mining management systems.
7. Hashrate and Efficiency Monitoring: Regularly monitor the hashrate and power efficiency of your M66S+ miners， comparing them to the manufacturer’s specifications. Significant deviations may indicate the need for maintenance or component replacement.
