Advanced CoolIT Liquid-Cooled Ready Servers
Release time：2025-09-18
A liquid cooling solution outperforms air as liquid transfers heat more efficiently than air, and GIGABYTE has liquid cooled designs.
Liquid-cooled servers use a liquid, rather than air, to remove heat from high-density, high-performance computing components like CPUs and GPUs, making them more efficient, allowing for greater server density, and reducing overall energy consumption and costs compared to traditional air-cooled servers. Types of liquid cooling include
direct-to chip (DLC), where cold plates contact components, and immersion cooling, where servers are submerged in a liquid dielectric fluid. These systems require components like coolant distribution units (CDUs), pumps, and specialized heat exchangers to manage heat transfer and are ideal for demanding applications such as AI, machine learning, and high-performance computing (HPC).
How Liquid Cooling Works?
Heat Transfer:
Liquid coolant, such as water or specialized fluids, absorbs heat from components like CPUs and GPUs more efficiently than air.
Circulation:
A system of pumps, pipes, and coolant distribution modules (CDMs) circulates the liquid through the server.
Heat Removal:
The heated liquid then flows to a coolant distribution unit (CDU) and a heat exchanger, which transfers the heat to the external environment.
Types of Liquid Cooling
Direct-to-Chip (DLC):
Cold plates are mounted directly onto the server's heat-generating components, removing a significant portion of the heat.
Rear Door Heat Exchangers (RDHx):
Liquid-cooled heat exchangers are installed on the back of server racks to capture hot exhaust air.
Immersion Cooling:
Servers are fully submerged in a dielectric fluid, which offers the highest efficiency by directly immersing the components.
Benefits of Liquid-Cooled Servers
Enhanced Cooling:
Liquid is a more efficient heat transfer medium than air, allowing for faster and more effective cooling of high-power components.
Increased Server Density:
Liquid cooling enables higher-density data center designs, allowing more powerful servers to be placed in a smaller space.
Improved Sustainability:
Reduced energy use for cooling leads to lower energy costs and a smaller carbon footprint compared to air-cooled systems.
Higher Performance:
By removing heat more effectively, liquid cooling allows CPUs and GPUs to operate at their full potential, boosting performance for demanding workloads like AI and HPC.
Noise Reduction:
Liquid-cooled systems can reduce the reliance on noisy internal fans found in air-cooled servers.
