In today’s world, chips in processors and GPUs can easily consume 300W+ of power. Cooling these high-performance chips is becoming increasingly challenging. To prevent overheating, large heatsinks and extremely high airflow from fans are necessary; fans that consume a significant amount of energy and generate unwanted noise. In fact, in modern, powerful servers, fans can account for up to 30% of the total power consumption.
But what if we could eliminate the need for these energy-hungry, noisy fans?
In a demo, we showcase a simple heating element, purely for illustration, that stays cool without a heatsink when immersed in dielectric fluid. The fluid absorbs the heat rapidly, causing it to become less dense and rise. This upward flow creates a natural convection cycle that continuously draws in cooler fluid to maintain a stable temperature, all without the need for fans and pumps.
This not only cools the power hungry chips, but also the voltage regulators (VRM), memory, networking cards and all other parts consuming energy and with that generating heat.
What’s even more exciting is that by using immersion cooling, we can achieve significant energy savings in cooling systems. Thanks to higher cooling water temperatures, often between 30°C to 45°C, immersion cooling reduces the need for lower-temperature chilled water. In many cases, this can reduce water consumption to almost zero.
And as a bonus, this effortless process results in high-quality hot water that can be used to heat houses, buildings, or industries.
If you want to learn more or see this technology in action, feel free to visit our Experience Center in Ede, Netherlands. We’re also hosting a demo event in London on Wednesday, February 19th. Additionally, we’ll be at Data Centre World London on March 12th and 13th, 2025, and at CloudFest in Rust, Germany, from March 17th to 20th.
Feel free to contact us for any questions or visit us at one of the events.
