A future-proof solution: Liquid Cooling

In the rapidly evolving landscape of data center operations, staying ahead of the curve is essential.  As the demand for computational power continues to surge, traditional air cooling methods are reaching their limits in terms of effectiveness, efficiency, and scalability. This is where innovative liquid cooling solutions, like Accelsius' NeuCool™ 2-Phase direct-to-chip (DTC) system, come into play, offering a sustainable, forward-looking approach to data center cooling.

Liquid cooling has gained significant traction in the industry due to its ability to address the ever-increasing heat dissipation challenges of modern IT equipment, also known as the “Thermal Wall.”  By directly cooling the heat-generating components, such as CPUs and GPUs, 2-Phase direct-to-chip liquid cooling enables cost effective and efficient heat extraction, ensuring optimal performance and longevity of the IT equipment and infrastructure.

One of the key advantages of direct-to-chip liquid cooling is its scalability.  As data center operators strive to accommodate the growing demands of high-performance computing, direct-to-chip liquid cooling provides a flexible and efficient solution that can allow for rack densification and drastically reduce IT hardware footprint requirements.  The Accelsius NeuCool™ 2-Phase direct-to-chip system incorporates a configurable design that allows for cost effective liquid cooling of one rack or an entire facility.  The familiar form factor allows the NeuCool™ solution to easily adapt to the myriad of infrastructure formats currently deployed and is more adaptable to future infrastructure developments than both immersion and single-phase water-cooled solutions.  Lastly, 2-Phase direct-to-chip cooling allows for the greatest headroom as it relates to the rising thermal output of next generation processors, GPUs, and memory.

Moreover, liquid cooling eliminates the limitations imposed by air cooling, such as airflow constraints and hotspots. By eliminating the reliance on airflow, liquid cooling enables data center operators to achieve higher equipment densities, optimize server placement, and maximize the utilization of available space. This translates into higher computing capacity within the same physical footprint, driving cost savings and efficiency gains.

In terms of energy efficiency, liquid cooling has a distinct advantage over air cooling. By removing heat directly from the source, liquid cooling significantly reduces the energy consumption associated with cooling infrastructure, such as fans and air conditioning systems. This translates into improved power usage effectiveness (PUE) and overall energy savings, contributing to a greener and more sustainable data center operation.

Accelsius' NeuCool™ solution takes liquid cooling to the next level with its advanced two-phase direct-to-chip technology. By utilizing an engineered dielectric fluid, NeuCool™ offers enhanced thermal performance, stability, and reliability without many of the risks associated with single phase water technologies. The innovative design of NeuCool™ ensures efficient heat transfer and minimizes thermal resistance, enabling data centers to achieve remarkable cooling efficiencies and maintain optimal operating conditions for their critical IT infrastructure.

By adopting Accelsius' NeuCool™ solution, data center operators can future-proof their cooling infrastructure and unlock a host of benefits. With its scalability, energy efficiency, and advanced thermal management capabilities, NeuCool™ empowers data centers to handle the increasing heat loads of emerging technologies, such as high-performance computing, artificial intelligence (AI), and machine learning (ML). It enables data centers to push the boundaries of performance while ensuring sustainability and cost-effectiveness.


Efficiency and sustainability are two crucial pillars of modern data center operations. As we have explored in this blog, understanding the distinctions between these concepts is vital for data center operators seeking to optimize their infrastructure and drive innovation. We have examined how efficiency encompasses factors such as power usage effectiveness, cost reduction, and performance gains, while sustainability focuses on minimizing environmental impact and promoting long-term viability.

Throughout this journey, we have highlighted the transformative potential of liquid cooling, particularly Accelsius' NeuCool™ solution. By directly cooling critical components, liquid cooling offers future proofed heat mitigation, scalability, and improved energy efficiency compared to traditional air-cooling methods. The benefits of liquid cooling extend beyond immediate gains in performance and cost savings, empowering data centers to adapt to emerging technologies and future-proof their operations.

Accelsius' NeuCool™ solution stands out as a leading-edge liquid cooling technology that aligns with the goals of efficiency, sustainability, and innovation in the data center space. Its advanced two-phase direct-to-chip (DTC) technology, combined with engineered dielectric fluid, enables data centers to achieve exceptional cooling efficiencies and maintain optimal operating conditions for their IT infrastructure. By embracing NeuCool™, data center operators can confidently navigate the ever-evolving landscape of high-performance computing, AI, and machine learning.
