Impact of Liquid Cooling

Liquid cooling is rapidly transforming the data center landscape, especially for high-density environments driven by AI, hyperscale computing, and mission-critical workloads. Aeons Technologies delivers server racks engineered for optimal compatibility with advanced liquid cooling technologies — including manifolds, Coolant Distribution Units (CDUs), and Rear Door Heat Exchangers (RDHX) — ensuring unmatched thermal performance, efficiency, and reliability.

Why Liquid Cooling Matters

Traditional air cooling struggles to meet the demands of modern high-density IT loads. Liquid cooling provides superior heat removal, reduces fan power consumption, and enables higher rack densities without compromising performance. The impact is measurable — both in operational cost savings and in environmental sustainability.

Key Takeaways from the Efficiency Impact of Liquid Cooling

1. Rethinking Metrics Beyond PUE

Power Usage Effectiveness (PUE) has long been the benchmark for cooling efficiency. However, liquid cooling influences both the IT power (denominator) and total facility power (numerator), making Total Usage Effectiveness (TUE) a more accurate metric.
TUE Formula:
TUE = ITUE × PUE
Where ITUE = Total Energy into IT Equipment ÷ Total Energy into Compute Components.

Aeons Technologies’ rack systems, when integrated with high-efficiency liquid cooling, help achieve up to 15% improvement in TUE compared to traditional air-only solutions.

2. Significant Energy Reduction in High-Density Deployments

Studies indicate that a hybrid air-liquid cooling strategy can yield over 10% total power reduction in data centers. Aeons racks support direct-to-chip cooling designs that can handle up to 75% of IT load through liquid cooling, reducing dependence on energy-intensive CRAC/CRAH systems.

3. Optimizing Thermal Performance and Heat Reuse

With Aeons RDHX-equipped racks and high-capacity manifolds, liquid cooling can operate at higher inlet temperatures — up to 45°C (113°F) — enabling hot-water cooling and opening opportunities for waste heat recovery. This means less chiller load, more free cooling hours, and lower carbon footprint.
