Optimal Operating Temperature Ranges for ANTMINER Models

Start with safety and logs

Power down before opening a miner, label cables before moving boards, and capture logs before repeated reboots erase useful evidence. Record model, firmware, pool, uptime, fan speed, temperature, reject rate, chain count, and the exact error text.

Confirm the fault class

Separate configuration faults from hardware faults first. Pool errors, DNS failures, bad worker names, overheating, weak power, fan faults, and missing hashboards can look similar from the dashboard but require different fixes.

Document the test path

Change one variable at a time and keep the before/after result. Note cable swaps, PSU swaps, firmware changes, pool changes, fan replacements, ambient temperature, and whether the fault follows a hashboard, control board, network, or power source.

When to escalate

Escalate to professional repair when there is a burned smell, melted connector, breaker trip, corrosion, repeated hashboard loss, liquid exposure, or a board-level fault that returns after a basic cable, power, firmware, and airflow check.

After the fix

Run the miner long enough to confirm stable accepted hashrate, fan behavior, chip temperature, reject rate, and pool-side reporting. A dashboard that looks normal for five minutes is not enough evidence for a recurring power, heat, or hashboard fault.

Understanding the specific operating temperature ranges of your miners is crucial for ensuring their efficient and prolonged functionality. These values refer to the intake air temperature, which may vary from the ambient room temperature due to factors such as dust accumulation.

When needed, please clean your miner to maintain optimal intake air temperature. Refer to our guide on miner maintenance and dust removal for more information.

All our ANTMINER models have a built-in protection program that automatically shuts down the miner if the temperature exceeds the allowable range. For more details on high-temperature alerts and protection measures, please refer to our dedicated guide.

Here are the maximum operating temperatures, measured in degrees Celsius, for various ANTMINER models:
