Professional Miner Maintenance suggestions from Antminer technicist

A visit to Antminer after-sale service department: professional suggestions on miner-maintenance from Antminer technicians that help you extend the longevity of your miners.


  1. Antminer must adopt the original brand of cooling fans since the quality of other brands cannot be guaranteed.
  2. High-speed fans cannot be replaced by low-speed fans, however the low-speed fans can be replaced by the high-speed ones.
  3. Regular dust removal is very important. Do not dismantle the miner. Use high-pressure blower to blow the dust backwards at the interval of one month.
  4. Reducing noise needs to reduce the fan speed, however, the effect of heat dissipation will not be guaranteed. Therefore, it’s hard to reduce the fan noise. More Antminer models may attempt to try water cooling in the future.
  5. It is not recommended to dispose the Antminer in oil for heat dissipation.
  6. The most proper indoor temperature for miner operation is 20-30℃.
  7. The chip temperature should be controlled at about 70-80℃, overheating may result from the dust accumulation.
  8. As for the issue of low chip temperature, if the miner operation is normal, the fan will run at low speed with less power consumption.
  9. Monitor the miner temperature all the time. Pause if some problems occur. The temperature difference of hashboard should be within 10℃.
  10. There are many reasons for hash speed decreases. And HW refers to the hardware error rate, which will result in miner restart at certain percentage. If the problem occurs frequently, return the miner to the manufacturer for maintenance.
  11. The miner can still run even one of the hashboards has been damaged, however, the income will be affected.
  12. When the miner has been used for some time, about 5% of hash speed decrease is acceptable.
  13. Good miner maintenance will greatly prolong the service life.
  14. Failure of IP detection may result from IP conflict.
  15. Download the firmware from the official website. Be sure to select the correct firmware, otherwise the program may be changed to result in malfunction.
  16. Download the batch software to connect multiple miners to the same computer for configuration.
  17. Unauthorized hashrate change or use of third-party firmware will make warranty invalid.
  18. Because of different algorithms, the specific cryptocurrency can only be mined with specific model of miner.
