Comparing CRAH and Liquid Cooling Systems Failure Modes

Posted by - November 18, 2025

High-density data centre facilities necessitate accurate, dependable cooling to avoid thermal runaway and equipment failure. Two popular approaches—Computer Room Air Handler (CRAH) units and liquid cooling systems—each provide distinct operational hazards. Understanding their failure modes is critical for maximising uptime, designing redundancy, and addressing the cooling requirements of AI, HPC, and hyperscale workloads. Mechanical Complexity
