In light of the current Greenland discussion, we present our first development in the Polar Line: the highly optimized Bitaxe Gamma "Greenland" for outstanding performance with one or optionally two Noctua fans. €5 from every miner sold will be donated to Transparency International Greenland.
The Polar Line models bridge the gap between the entry-level Eco Line and the high-performance Ice Line. The massive aluminum "Bitchin Sink" cooler from The Solo Mining Co. ensures optimal ASIC cooling, complemented by one or optionally two extremely quiet Noctua NF-A4×20 PWM fans (5V, 40 mm × 20 mm, including Y-splitter if optional) plus two high-quality, all-copper heatsinks at the front and rear for active V-Reg cooling. All Made in Germany
1. Performance data
- Hashrate: Factory set to 1.3 TH/s
- ASIC chip: BM1370 (identical to the Antminer S21 Pro)
- Power consumption: approx. 19 watts
- Integrated Wi-Fi module (ESP32-S3-WROOM-1) for easy wireless integration
- Configure Wi-Fi: First, connect to the miner's access point (QR code on the display or connect directly to the miner's Wi-Fi).
- Open the settings in your browser and connect the miner to your home Wi-Fi.
- Enter your Bitcoin address under "Pool": Enter your wallet address and your pool.
- Solo mining starts automatically after the restart.
4. High-quality hardware components
- Display: 0.91″ SSD1306 OLED for live monitoring of hashrate, temperature and status
- Aluminum cooler "Bitchin Sink" by The Solo Mining Co. + ultra-quiet Noctua fan NF-A4×20 PWM (40 mm × 40 mm × 20 mm)
- VRM cooling: Two all-copper heatsinks at the front and rear of the PCB plus an optional Noctua NF-A4×20 PWM (5 V, including Y-splitter)
- Power supply: 30W 6A power supply for light overclocking included
- (For increased overclocking, you will need a more powerful and stable power supply, e.g., the Leicke 50W 10A 5V power supply of German quality.)
- Rare green PCB for the “Greenland” look
- Arctic MX-7 thermal paste
- Heavy Load Stand in Arctic Green designed by @TK_2119913
- Printed using a sustainable 3D printing process, Made in Germany
The achievable hashrate and efficiency depend significantly on the chip clock speed. Overclocking without adequate cooling can lead to damage. No warranty is provided for damage caused by overclocking or future firmware updates beyond the factory settings.
