Product Structure

5.1 PWM Fan

Automatically adjusts fan speed based on chip temperature to balance cooling and noise.

5.2 ASIC Heatsink

Heat-pipe based heatsink designed to efficiently cool the core hashing chips.

5.3 Power Chip Heatsink

Independent cooling structure that reduces temperature of power management chips for better long-term stability.

5.4 Interface Area

XT60 power connector + Status indicator LED (if applicable).

Important: Do not block the air intake or exhaust vents. Ensure proper airflow at all times.

Installation & Power-On

1. Place the device on a stable and well-ventilated surface.
2. Use the included 250W switching power supply.
3. Securely connect the XT60 power connector.
4. Connect to AC power to start the device.

Caution: Do not plug or unplug the XT60 connector while the device is powered on.

Network Configuration (WiFi 2.4G/5G & RJ45)

• The device supports WiFi 2.4G / 5G and RJ45 wired connection.
• Network configuration is completed via the web management interface after power-on.

Mining Modes

Cooling & Noise

• The PWM fan automatically adjusts speed based on temperature.
• Typical operating noise is below 40 dB.
• Increased fan speed under high load is normal.

Frequently Asked Questions

Q1: Is hashrate or power fluctuation normal?
A1: Yes. Hashrate ±5% and power ±10% are within normal operating ranges.

Q2: The fan noise is loud after startup. Is this normal?
A2: Yes. During startup or under high load, the PWM fan may increase speed temporarily to enhance cooling. This is normal behavior.

Q3: The device temperature seems high during operation. Is this an issue?
A3: ASIC miners generate significant heat. As long as the device operates within 0-35 °C, this is normal.

Q4: Will the power consumption always stay at 160W?
A4: No. Power varies with load, ambient temperature, and conditions. 160W ±10% is normal.

Q5: Can the device be used in a closed cabinet or enclosed space?
A5: No. Enclosed spaces restrict airflow and may cause overheating, throttling, or protective shutdown.

Q6: Will the device resume mining automatically after a power outage?
A6: Yes. If network and mining configurations remain unchanged, the device will auto-resume after power is restored.

Q7: Does the device support 5G WiFi?
A7: Yes. The device supports WiFi 2.4G/5G & RJ45.

Q8: What should I do if the device cannot connect to the network or frequently disconnects?
A8: Check: ensure WiFi is 2.4G/5G or use RJ45; verify router signal strength and network stability; remove potential interference sources.

Q9: Does the device guarantee mining profits?
A9: No. Profitability depends on network difficulty, pool rules, electricity costs, and other external factors.

Q10: What should I do if performance decreases after long-term use?
A10: Regularly check for dust buildup at air intake and exhaust vents, and maintain proper ventilation.

Q11: What is the maximum Core Vol setting?
A11: Do not set Core Vol above 1.30V. Higher values may trigger the power adapter protection and cause shutdown or instability.

Safety Notice

Do not disassemble or modify the device.
Do not block the cooling airflow.
Do not use the device in humid or high-temperature environments.
Power off immediately if abnormal behaviour occurs.
