Liquid Cold Plate Cooling for Server CPUs
Why Air Cooling Fails Modern Server Demands
The Limitations of Traditional Thermal Management
Air-cooled server CPUs face critical challenges as computational demands skyrocket:
▶️ 40-45% of data center energy consumed by cooling systems (Uptime Institute, 2023)
▶️ 65 dB+ noise levels from high-RPM fans impacting workplace environments
▶️ Thermal throttling reduces CPU performance by up to 30% at 85°C+
The Breaking Point: A 2023 hyperscale data center study revealed air-cooled racks hitting 15kW density limits, forcing costly infrastructure expansions.
