Power Innovations with Direct Liquid Cooling and High-Performance Computing

Direct Liquid Cooling

As the rapid adoption and development of AI emerges, digital technologies continue to advance and boost the demand for processing large, complex workloads at an increasingly faster rate than ever. These workloads require high-performance computing (HPC) and extremely efficient data center processing.

The traditional air-cooling systems in data centers may not be able to cater to HPC needs. This is where Direct Liquid Cooling comes into play.

Direct Liquid cooling (DLC) uses a liquid, such as water, or a refrigerant, rather than air, to cool the data center. By allowing the cooling solution to be brought closer to the heat source, it operates in a more effective manner in terms of power consumption. Processors can operate significantly faster using this method compared to other traditional and conventional means.

By adopting Direct Liquid Cooling alongside with air-cooling strategies, data centers can improve their Power Usage Effectiveness (PUE) and reduce energy consumption, thus supporting the growing demand for HPC.

How Direct Liquid Cooling can maximise space utilisation and efficiency of the data centre

A tour of the HPC Zone in NTT data center can be scheduled for an on-site demonstration.



Dell thermal management with direct liquid cooling is 5 times more effective than traditional air cool compute resources. 


Enhanced PUE

With NTT Direct liquid cooling data center infrastructures, the Power Usage Effectiveness (PUE) can be up to 10% more effective.


Cost Saved

As the data center racks now have the cooling capacity to host more high-performance computers, each rack can host more server equipment than before. Therefore, saving real estate cost.


kW Per Rack

Each data center rack can now support more than 50kW per rack which is 2 times more than the maximum setup for most data center rack.

Four Reasons Why Our Liquid Cooling Is So Cool

Unleash Performance

Forget throttling. Liquid's superior heat transfer coefficient removes heat from servers faster and more efficiently than air to keep your servers at peak performance when training and running AI models.

Greenify AI Footprint

Liquid cooling requires less energy than traditional air cooling, reducing your carbon footprint, allowing you to meet Scope 3 requirements, and aligning with a greener future.

Maximise Density

Pack more processing power into your data centre space with liquid cooling, maximising space utilisation and efficiency and maximising the most of your investment.

Designed for Flexibility

Unconstrained by airflow limitations, liquid cooling adds flexibility to data centre design and removes the need for raised floors. It optimises your rack space and allows you to get the full potential of the data centre layout.
