4× RTX Pro 6000 Blackwell on Water, and the One Card That Wouldn't Behave
Summary
A detailed hands-on post about cooling four RTX PRO 6000 Blackwell GPUs in water, converting them for long-running AI training workloads. It covers a pilot-card failure, hardware failure analysis (cracked VRM choke), a warm-disassembly technique, microsoldering repairs, and final performance results showing stable, high-throughput training and concurrent inference.
