GPU Cooler: AI/HPC Performance Analysis
Comparing Air vs. Liquid Cooling for High-Density GPUs
Performance per Watt (FLOPS/W)
With Liquid cooling, NVIDIA H100 achieves 140 TFLOPS/W. This is 40% higher than Air cooling.
Temperature Delta (Die - Inlet)
Liquid cooling achieves a 20°C lower die-to-inlet temperature, reducing thermal stress and risk of throttling.
Rack Density (GPUs per Rack)
16 GPUs
32 GPUs
Liquid cooling enables 2x higher density in the same data center footprint.
Sustained GPU Performance Under Load
This chart illustrates how air-cooled GPUs (red line) can experience performance degradation from thermal throttling, while liquid-cooled GPUs (blue line) maintain consistent peak performance.
Operational & Environmental Benefits of Liquid Cooling
Faster Results
Up to 1.4x performance gain by eliminating thermal throttling, completing AI/HPC tasks significantly faster.
Reduced Footprint
Enables much denser rack deployments and smaller data center footprints.
Improved Reliability
Lower, stable operating temperatures can extend component lifespan and improve system reliability.
Energy Efficiency
Contributes to lower PUE and carbon emissions and enables easier capture and reuse of waste heat.
