Immersion Cooling
Immersion cooling is a next-generation thermal management solution where servers are fully submerged in dielectric fluid, allowing direct heat transfer from components. This method eliminates the inefficiencies of air cooling, supports ultra-high-density compute and drastically reduces energy consumption. Ideal for HPC, AI/ML and blockchain workloads, immersion cooling enables sustainable, high-performance infrastructure with minimal footprint and maximum thermal stability.
CoolBlock, powered by Synapsecom, delivers modular immersion cooling systems engineered for enterprise-grade deployments. Built for scalability and efficiency, CoolBlock’s platform transforms traditional data center operations into environmentally optimized, high-density compute environments.
[02] benefits
Liquid Immersion Cooling Fluids
Better performance
By transferring heat more efficiently than many air-cooling techniques (which use refrigerated air, fans and heatsinks), immersion cooling fluids can support overclocking and increase CPU speeds by up to 40%.
More efficient
operations
With no need for coolers, chillers, fans or evaporative cooling systems, immersion cooling fluids can help businesses cut the floor space needed to host their computing equipment by up to 80%.
Greater energy efficiency
Immersion cooling fluids almost eliminate the need for the power-hungry air-based cooling systems, helping to reduce the energy footprint of a computing facility by up to 48%.
Increased profitability
By reducing electricity consumption and the need for intricate heating, ventilation and air conditioning systems, immersion cooling fluids can reduce a data centre’s total cost of ownership (TCO) by up to 33%.
Easier to scale
As data centres expand to meet the growing demands of high-end computing, immersion cooling fluids offer an easier way to add scale and enable increased locational flexibility.
Improved sustainability
Providing greater operational and energy efficiency, immersion cooling fluids help businesses to achieve their sustainability goals – contributing to CO₂ emissions reductions of up to 30%.

[06] comparison
Immersion
vs Air Cooling
Historically, data centres have depended on air-based cooling systems, which involve complex setups including fans, heatsinks and other bulky components to maintain safe operating temperatures. These systems often compromise efficiency due to their substantial space requirements and high energy demands.
Immersion cooling presents a transformative alternative. By enveloping hardware in specially engineered cooling fluids, it efficiently draws away heat directly from the source. This method not only enhances temperature control and boosts equipment performance, but also significantly improves energy usage and overall operational efficiency.
