Intel and Submer's Cool Collaboration: FCHS Immersion Tech for 1000W CPU Cooling

Written by Boldson on 16 October 2023. Posted in Hardware

Intel and Submer have joined forces to bring forth an innovation that promises to redefine CPU cooling capabilities. Known as the "Forced Convection Heat Sink" or FCHS, this development aims to take thermal dissipation to new heights, allowing CPUs rated at up to 1000W to stay chill.

Intel and Submer Illuminate the Path to Immersion Cooling for 1000W TDP

For those unfamiliar with Submer, it's a Spanish company specializing in enabling data centers worldwide, with a focus on managing cooling solutions for HPC, hyperscale, data centers, Edge, AI, DL, and blockchain applications. As technology progresses, the power drawn by individual components has been on the rise, making effective cooling a paramount concern. The FCHS package combines the efficiency of forced convection with passive cooling, enabling the cooling of high TDP CPUs and GPUs in single-phase immersion systems.

While the official workings of FCHS remain a well-kept secret, it appears to leverage liquid cooling and two cold plates to enhance thermal transfer and aid the cooling process. According to reports, Intel and Submer have successfully run an undisclosed Xeon processor (likely Sapphire Rapids) at over 800W, edging closer to the 1000W milestone.

Apart from its upgraded cooling capabilities, FCHS boasts cost-effectiveness. Its components are inexpensive to manufacture and offer the potential for 3D printing. Designed for easy integration into existing server and immersion tank setups, the FCHS empowers data centers to handle high-density compute workloads seamlessly.

The FCHS delivers thermal resistances comparable to Direct Liquid Cooling (DLC), establishing it as a formidable contender in the liquid cooling landscape. In addition, the package allows for thermal management control via BIOS PWM, putting the server in charge if desired.

This technological leap paves the way for even higher TDPs and future collaborations, consolidating single-phase immersion as a leading cooling solution. In the world of CPU cooling, it appears immersion is here to stay, providing stiff competition to other liquid cooling technologies.

So, if you've ever dreamt of running a CPU at 1000W while keeping it cool, this innovation might just be the ticket to your high-powered dreams.
