How to maintain and extend the lifespan of your ASIC miner: a complete guide 2025

An ASIC miner can operate more than 5 years if it is well maintained. Premature breakdowns almost always come from the dust, heat, and power surgesHere is the complete Minent.fr guide to preserving your machines (Antminer, Whatsminer, IceRiver, Goldshell…) and guaranteeing sustainable 24/7 operation.

1️⃣ Air cleaning and filtration

Dust is the number one enemy of air-cooled ASICs. It accumulates on heatsinks and fans, reducing cooling efficiency and increasing the risk of overheating.

Best practices

• Install a MERV 8 to 13 filter or equivalent on the air intake.
• Clean the filters every week (blowing or replacing).
• Gently blow the heat sinks with dry compressed air every 30 days.
• Avoid dusty or humid environments.

Trick : A well-maintained filter extends the life of your fans by 50 to 70%.

2️⃣ Thermal management

Every additional 10°C reduces the lifespan of electronic components by half. Maintaining a stable temperature is therefore essential.

• Monitor the temperature chips (ASIC chips): ideally between 60 and 80 °C.
• Ensure a constant airflow: cool intake, unobstructed hot exhaust.
• Avoid sudden temperature changes (condensation).
• If possible, opt for hydro Or immersion if the climate is hot.

Alert temperature: +90 °C = risk of throttling, +100 °C = immediate danger.

3️⃣ Electrical maintenance and surge prevention

A power surge or micro-interruption can damage the PSU or hash boards. Good electrical protection significantly increases reliability.

Absolutely must be installed

• Uninterruptible Power Supply (UPS) Or surge protector upstream of the line.
• Residual current circuit breaker + earth resistance checked < 10 ohms.
• Suitable cable cross-section (H07RN-F, 2.5 mm² min. for 16 A).
• Tight connectors and checked every 3 months (avoids arcs and overheating).

Trick : use a wattmeter to monitor actual consumption and detect PSU anomalies.

4️⃣ Firmware et monitoring

Firmware updates improve stability, thermal management, and fix bugs.

• Check the official firmwares on Bitmain, MicroBT, IceRiver, etc.
• Avoid uncertified firmware if you are not an expert.
• Enable temperature, hashrate and network error alerts.
• Surveillez vos ASIC via Minerstat, Foreman, HiveOS ou dashboard pool.

Ruler : 1 stable mining < 0.5% of “rejected shares”.

5️⃣ Preventing mechanical breakdowns

• Replace the fans as soon as an unusual noise appears.
• Use silent blocks under the racks to limit vibrations.
• Check the PSUs: no odor, no electrical noise (arcing or clicking).
• Always unplug the miner before any internal intervention.

Average lifespan of Bitmain fans: 20,000 to 30,000 hours (≈ 2.5 to 3.5 years in 24/7).

6️⃣ Immersion cleaning (if applicable)

For the models in immersion (dielectric fluid):

• Control the level and clarity of the fluid every week.
• Replace the fluid every 18 to 24 months.
• Check the pumps, heat exchangers and seals.
• Avoid exposing the fluid to air (risk of oxidation and humidity).

7️⃣ Recommended Maintenance Schedule

8️⃣ Advanced tips from Minent.fr

• Use a Wi-Fi sensor (Sonoff, Shelly) to track consumption & alerts.
• Place your minors on metal grilles (low air circulation).
• Optimize off-peak hours or local energy sources (solar, hydro).
• Keep a parts inventory : fans, PSU, power cables, filters.

Conclusion

Regular maintenance ensures consistent performance, fewer breakdowns, and better long-term profitability. A well-maintained ASIC can last up to... 30% longer lifespan and reduced noise. Make it a routine: cleaning, electrical checks, temperature, firmware, and your machines will run like new.
