ST Telemedia Global Data Centres Unveils Direct-to-Chip Liquid Cooling Showcase in Thailand

Showcasing advanced cooling technologies already supporting operational AI clusters, high-density racks, and live customers at Thailand’s first NVIDIA DGX-Ready data centre

Bangkok, Thailand, 24 April 2025 — ST Telemedia Global Data Centres (STT GDC), a leading data centre service provider in Asia, today announced the launch of a direct-to-chip liquid cooling showcase at its flagship STT Bangkok 1 data centre facility. This showcase highlights the advanced cooling technologies already in use at the facility, which has recently achieved certification in the NVIDIA DGX-Ready Data Center programme and currently supports operational AI clusters, high power density racks, and live AI customers. 

Over the past year, STT Bangkok 1 has proven its ability to support some of the market’s most demanding accelerated computing workloads, with operational AI clusters and high-power density racks already live in the facility. The showcase offers a first-hand look at the advanced liquid cooling solutions underpinning these deployments, underscoring STT GDC’s ongoing commitment to sustainable digital infrastructure and continued innovation. 

The direct-to-chip liquid cooling system, already operational at STT Bangkok 1, delivers targeted thermal management by circulating coolant directly to the compute components. This enables the facility to achieve greater operational efficiency, support ultra-high rack densities, and reduce environmental impact—critical for the growing demands of AI and high-performance computing (HPC) customers.

Data centres are the backbone of today’s digital society, powering everything from content streaming and cloud computing to artificial intelligence (AI) workloads. As the volume of global data creation continues to explode—driven by AI, mobile internet, and cloud adoption—data centres are under pressure to deliver higher performance while managing rapidly growing heat loads and energy demands.

“We are proud to introduce this state-of-the-art liquid cooling solution at our Thailand facility, marking a pivotal step in redefining the future of data centres in the region,” said Budsarin Pradiyont, country head - Thailand, ST Telemedia Global Data Centres. “As digital transformation accelerates across Asia, our customers require robust, future-ready infrastructure that delivers both exceptional performance and environmental responsibility. This showcase demonstrates our ongoing investment in advanced technologies that are shaping the future of data centres, and reinforces our commitment to enabling a smarter, greener digital future for businesses and communities throughout the region.”

Why liquid cooling?

Higher rack densities, particularly for accelerated computing workloads such as AI, generate more heat — pushing traditional air cooling beyond its efficient limits. This leads to overheating risks, higher operational costs, and greater environmental impact.

Direct-to-chip liquid cooling addresses these challenges by circulating coolant directly over the compute components—such as CPUs and GPUs—via cold plates and a network of distribution pipes. This method removes heat at the source, allowing the system to:

• Achieve up to 30% greater energy efficiency compared to traditional air cooling, with the potential to reduce cooling energy consumption by 20–30%.
• Support ultra-high rack densities of at least 150kW per rack, far exceeding the 20–30kW/rack limit of air-cooled systems and paving the way for next-generation AI and high-performance computing.
• Extend equipment lifespan by minimising thermal cycling and hot spots, resulting in fewer component failures and improved reliability.
• Optimise space utilisation, with liquid cooling solutions occupying a maximum of 60% of the space required by traditional air-cooled data halls. By targeting heat-generating components directly, this localised thermal management reduces the need for large-scale cooling infrastructure, further enhancing the efficient use of space.

The direct-to-chip liquid cooling system is expected to deliver substantial reductions in power usage effectiveness (PUE) and water consumption, aligning with STT GDC’s broader sustainability goals. The showcase will also serve as a platform for collaboration with technology partners, customers, and industry stakeholders to explore the adoption of liquid cooling at scale.

Driving Sustainable Innovation and Economic Growth

The showcase demonstrates STT GDC’s leadership in sustainable innovation, supporting Thailand’s ambition to become Southeast Asia’s premier AI data centre hub. The region has seen over US$30 billion committed to AI infrastructure in the first half of 2024, with Thailand emerging as a key beneficiary^[1] . This influx of investment is laying the groundwork for more compute power, AI services, and the capacity to handle ever-growing data volumes, positioning the region for long-term success.

By adopting direct-to-chip liquid cooling, STT GDC is not only enabling high-performance AI and analytics workloads but also advancing its goal of achieving carbon neutrality by 2030. The technology’s efficiency and sustainability benefits are critical for Thailand’s digital economy, which is projected to grow at a five-year CAGR of 27.1%^[2]  and support transformative applications across sectors.
