When the miner is used at an altitude from 900m to 2000m, the highest operating temperature decreases by 1°C for every increase of 300m.

Important Notes

• Tolerances: Official specifications state actual hashrate value fluctuates by ±3%, and actual power on wall and power efficiency fluctuate by ±5% .

• Efficiency Consistency: All three S21 Pro variants share the same 15.0 J/TH efficiency rating, making the 245T model the most productive per unit while maintaining identical power efficiency .

• Target Audience: The S21 Pro series is designed for professional miners, hosting clients, and large-scale mining farms seeking maximum efficiency and ROI per kWh. With noise levels of approximately 75 dB, it is not suitable for home or office environments without dedicated soundproofing.

• Recommended Electricity Rate: For best ROI, the S21 Pro performs optimally at electricity rates below $0.07/kWh.

• Comparison to Standard S21: The S21 Pro (15.0 J/TH) offers significantly better efficiency compared to the standard S21 (17.5 J/TH) with higher hashrate output .

• Most Common Configuration: According to market data, the 234 TH/s variant is the most common configuration found on the secondary market
