Goldshell SC5 Pro II Air Cooling Siacoin Miner 14Th/s 3300W For Sale

The Goldshell SC5 Pro II is a next-generation ASIC miner engineered specifically for the Blake2B-Sia algorithm. It is purpose-built for mining SiaCoin (SC), the native cryptocurrency of the Sia decentralized cloud storage platform. Its significance lies in delivering a major performance leap over its predecessor, offering up to 100% higher hash rate while maintaining the same 3300W power envelope, making it one of the most capable Blake2B-Sia miners on the market .

Compared to the previous SC5 Pro, the SC5 Pro II delivers:

✅ Higher Hashrate – More terahashes for greater mining potential
✅ Better Efficiency – Lower J/GH means reduced electricity costs
✅ Enhanced Hardware – Optimized components for superior stability
✅ Future-Ready Design – Built to remain competitive in the evolving SiaCoin mining landscape

Yes. While the SC5 Pro II achieves 14 TH/s at 3300W in its default high-performance configuration, it retains the operational flexibility characteristic of Goldshell miners :

• Default (Hashrate) Mode: Delivers the full 14 TH/s at 3300W for maximum output.

• Low-Power / Efficiency Mode: Reduces power consumption and hash rate (similar to the SC5 Pro’s 8.8 TH/s at 2020W mode) for miners prioritizing energy savings over raw performance.
  This dual-mode capability allows you to adapt to fluctuating electricity costs or environmental conditions.

The SC5 Pro II represents a generational leap in performance. Key improvements include:

• Hash Rate: 14 TH/s vs. 11 TH/s (a 27% increase in raw output) .

• Performance Leap vs. SC5: Up to 100% higher hash rate compared to the original SC5 model .

• Efficiency: 0.236 J/GH vs. the SC5 Pro’s 0.256 J/GH, making it approximately 8% more energy-efficient .

Profitability is dynamic and never guaranteed. It depends entirely on three key factors: the market price of Siacoin (SC), the Blake2B-Sia network mining difficulty, and most critically, your local electricity cost per kWh .

Based on a standard electricity rate of $0.10 per kWh, the SC5 Pro II consumes approximately $7.92 daily in electricity. At current market conditions, this can result in a modest daily net loss or a break-even scenario. However, at lower electricity rates (e.g., $0.04-$0.06/kWh), the miner can achieve positive profitability.

You must use a real-time mining profitability calculator (such as ASIC Miner Value) with your exact power costs for an accurate assessment.

Yes. Goldshell provides a comprehensive software ecosystem for fleet management :

• Goldshell Hub: A dedicated cloud platform that allows you to remotely monitor hashrate, temperature, fan speed, and profitability from anywhere .

• Mobile App Integration: Manage your miners via smartphone with real-time alerts and status updates.

• Remote Configuration: Adjust mining pools, update firmware, and restart devices without physical access.

For optimal performance and longevity:

• Operating Temperature: Maintain ambient temperatures between 5°C and 35°C.

• Humidity: Keep relative humidity between 10% and 65% (non-condensing) .

• Ventilation: Ensure adequate airflow around the miner; do not obstruct the dual-fan intake or exhaust.

• Altitude: Operate below 2000 meters for optimal cooling performance.

The lifespan depends on operating intensity, cooling conditions, and environmental factors like dust and humidity. With proper maintenance (regular cleaning, stable temperature, adequate ventilation), these miners can operate reliably for 3-5 years or longer. The SC5 Pro II is designed for 24/7 continuous operation in professional environments.
