The most common mistakes when installing an ASIC miner (and how to avoid them)
Installing an ASIC miner seems simple, but certain technical or environmental errors can quickly reduce its performance, or even damage it. Here is a list of most common mistakes and the good practices for a successful start, according to Minent.fr's experience.
1️⃣ Poor power supply
Typical mistake: connecting an ASIC to an undersized line or via a household power strip. A miner consumes between 2500 and 4000 W continuous operation — an unsuitable installation is a real risk.
Avoid
- Consumer power strips, slim extension cords, twisted cables.
- Lines shared with other powerful devices.
- No circuit breaker or grounding.
To do
- Line dedicated 230V with 20A circuit breaker and H07RN-F 3×2.5 mm² minimum cable.
- Certified PSU in good condition (never modified).
- Protection surge protector and 30 mA differential.
2️⃣ Poor cooling management
Mistake: Placing multiple miners in an enclosed space without sufficient ventilation. Result: accumulated heat, increased noise, and automatic throttling (hashrate drop).
Solutions
- Linear airflow: intake on one side, exhaust on the other.
- Target flow rate: 250–300 m³/h per kW dissipated.
- Dust filters on inlets, grilles on outlets.
- Ideal temperature: 20–35 °C (chips), < 45 °C (PSU).
Trick : For multiple machines, use directed ducts and an industrial air extractor (ducted or plenum).
3️⃣ Poor network or unstable IP
A common mistake is mining via Wi-Fi or powerline adapters. ASICs must operate with a direct Ethernet connection to avoid packet loss.
Recommendations
- Login Ethernet RJ45 direct to the router.
- Static IP address to avoid IP changes.
- High-quality network switch (Gigabit recommended).
Advice : Avoid low-end hubs and excessively long network extensions (> 20 m without a repeater).
4️⃣ Poor pool choice or incorrect configuration
Error: Entering incorrect pool addresses or forgetting credentials.
Best practices
- Choose a reputable pool (F2Pool, ViaBTC, Poolin, Luxor...).
- Check the Pool URLs (EU/US/ASIA region).
- Standard format: workername.miner a password “x”.
- Configure 3 pools (primary + 2 backups).
5️⃣ Poor ventilation or installation direction
Error: Reversing the airflow or blocking the side fans. ASICs blow air from front to back — never stick them against a wall.
To do
- Leave 30–40 cm of free space in front of and behind each miner.
- Avoid blind spots (hot air backflow).
- Place the machines on grids or perforated supports.
6️⃣ Absence de monitoring
Error: not monitoring temperatures, hashrate or rejection rate.
Solution
- Monitor via your pool or software (Minerstat, Foreman, HiveOS, etc.).
- Activate the automatic alerts (temperature, offline, share reject).
- Analyze your statistics weekly to identify any deviations.
Key indicators: Stable temperature, 0–0.5% of “rejected shares”, uptime > 99%.
7️⃣ Underestimated Noise
An Antminer operates at between 70 and 80 dB. Installing several machines in an unsuitable room can quickly become a noise nightmare.
Solutions
- Install the miners in a dedicated space or a ventilated, soundproof enclosure.
- To expect plenum + silencer on the air ducts.
- Avoid resonant metal structures (opt instead for MDF + foam enclosures). M1).
8️⃣ Forgetting about maintenance
Mistake: Never clean the filters, fans, or check the cables.
Monthly Checklist
- Blow out the grilles and fans with compressed air.
- Check that the PSU connectors are tight.
- Check for abnormal noise (fan, vibration, electrical arc).
- Update the firmware if available.
9️⃣ Not planning an emergency plan
Error: Unplug the miner directly without shutting down the software.
Good reflex
- Use the “Stop Mining” button on the dashboard before shutting down.
- Leave the fans running for 30 seconds before switching off completely.
- Disconnect the PSUs properly if storing them for an extended period.
Conclusion
A successful installation rests on three pillars: safe electricity, controlled cooling And stable network configurationBy following these best practices, your ASICs will operate optimally, quietly and sustainably.
