• BM1368 ASIC Chips: Optimized for sustained performance under high-load liquid cooling, delivering reliable hashrate and efficiency.

• Rigorous Validation: 72-hour stress tests (thermal shock, voltage stability, leak resistance) with video documentation.

2. Risk-Free Purchase Assurance

• 30% Deposit Reservation: Secure your order via crypto.

• Transparent Pre-Shipment Proof: Receive a customized test video showing real-time metrics (serial number, hashrate, chip health) in simulated immersion conditions.

• Immersion-Safe Packaging: Anti-static, moisture-proof sealing and shock-absorbent padding.

3. Long-Term Profitability

• Eliminate Zero Hashrate: Replace irreparable hashboards to resume full mining operations.

• Extend Miner Lifespan: Prevent cascading failures caused by liquid cooling system compromises.

Why Replace Faulty Immersion Hashboards?

A failing hashboard in liquid-cooled systems risks:

• 💧 Coolant Contamination: Burnt components can degrade dielectric fluid.

• ⚡ Total Shutdown: Zero hashrate halts all revenue.

• 🔧 System-Wide Damage: Compromised cooling efficiency damages adjacent hardware.

Ordering Process

2. 30% Deposit: Reserve your hashboard securely.

3. Review Immersion Test Video: Validate performance in simulated liquid cooling.

4. Finalize & Ship: Dispatched within 3-5 days with global tracking.

FAQs

Q: How is this hashboard different from air-cooled S21 models?
A: It features waterproof seals, corrosion-resistant materials, and enhanced thermal tolerance for immersion systems.

Q: Can I use this in non-immersion miners?
A: No—designed exclusively for liquid-cooled S21 Immersion rigs.

Q: What if fluid leaks damage the hashboard post-installation?
A: Ensure proper coolant maintenance. While no post-shipment warranties apply, our pre-testing minimizes defects.
