LG CNS turns to liquid cooling as AI servers push data centers to the limit
Summary
LG CNS said Wednesday that it is working with Naver Cloud to install direct-to-chip liquid cooling at its Samsong Data Center in Korea. The system is meant to support Nvidia’s next-generation Vera Rubin GPUs owned by the National IT Industry Promotion Agency under the Ministry of Science and ICT. The 80-megawatt facility is expected to become a major AI factory hub, and construction and testing are planned for completion by next year.
Key Facts
- The Samsong Data Center has a total power capacity of 80 megawatts.
- The liquid-cooling system is designed to handle server racks drawing more than 200 kilowatts.
- LG CNS said conventional air cooling generally handles power densities of about 20 to 30 kilowatts per rack.
- The global data center liquid-cooling market is projected to grow from $4.07 billion in 2026 to $27.65 billion in 2033, according to MarketsandMarkets.

LG CNS is bringing liquid cooling to a major data center in Korea as the rise of artificial intelligence (AI) pushes high-performance graphics processing units (GPUs) to consume more power and generate more heat.
LG CNS said Wednesday that it is working with Naver Cloud to install direct-to-chip liquid cooling at its Samsong Data Center, preparing the facility to support high-performance AI services.
The cooling system will support Naver Cloud’s operation of Nvidia’s next-generation Vera Rubin GPUs owned by the National IT Industry Promotion Agency, under the Ministry of Science and ICT.
The Samsong Data Center, with a total power capacity of 80 megawatts, is expected to become a major AI factory hub, with the liquid-cooling system designed to handle server racks drawing more than 200 kilowatts.
Direct-to-chip cooling uses cooling plates attached to GPU chips to absorb heat through circulating liquid, which transfers heat more efficiently than air.
Conventional air cooling generally handles power densities of about 20 to 30 kilowatts per rack, while high-performance GPU servers are moving beyond 200 kilowatts, according to LG CNS.
The company said the shift is making liquid cooling increasingly important for AI factories, where dense computing infrastructure must operate alongside power, cooling, networks and AI platforms.
LG CNS will combine its data center design, construction and operations capabilities with the cooling infrastructure, GPU server environment and power systems.
Naver Cloud will draw on its experience operating large-scale GPU services to provide high-performance AI services to public institutions and businesses.
The two companies plan to complete construction and testing of the liquid-cooling infrastructure by next year.
The global data center liquid-cooling market is projected to grow from $4.07 billion in 2026 to $27.65 billion in 2033, according to MarketsandMarkets.
