Redefining thermal management with unmatched performance and innovation

We are proud to announce that our cutting-edge technology has led to the development of the world's most powerful AI-designed liquid nitrogen (LN2) heatsink for extreme CPU cooling. This groundbreaking innovation was developed at the request of the renowned overclocking experts from SkatterBencher and ElmorLabs, and in collaboration with additive manufacturing expert 3D Systems. Through this innovation we have set a new benchmark in thermal management.

Unmatched performance and efficiency

Extreme CPU cooling using liquid nitrogen is becoming the standard for computer overclocking as it allows for extremely low temperatures that are required to enable the desired extreme clock speeds. By leveraging the cutting-edge capabilities of our ColdStream platform, our engineering team has generated a heatsink that redefines thermal performance of liquid nitrogen cooling.

By utilizing two-phase boiling physics in combination with some of the most sophisticated algorithms in the world, ColdStream generated a structure that maximizes heat transfer to the extreme while perfectly respecting the bounds of 3D printing manufacturability. Initial tests have demonstrated extraordinary results with a thermal resistance as low as 0.011K/W. That is 1.1°C of temperature difference between the heatsink base and the liquid nitrogen per 100W of CPU power, positioning it as one of the most powerful heatsinks in the world.

The heatsink was created using 3D Systems' Direct Metal Printing technology, utilizing certified oxygen-free copper for superior thermal conductivity of 390 W/mK. This cutting-edge approach allows for geometries that traditional manufacturing methods cannot achieve. Maintaining the purity of the copper powder during printing is of utmost importance as any oxygen in the copper matrix has a detrimental effect on its thermal conductivity.

Initial physical testing

Following its development, the LN2 heatsink underwent initial physical testing by ElmorLabs to validate its performance. The detailed initial evaluation confirms the predicted heatsink's exceptional cooling capabilities. The full performance report of the test campaign is available here. In particular, the 3x faster cooldown behavior compared to the Volcano LN2 cooler, one of the top products in the market today, stood out during testing. Because the AI design and the Volcano have an identical mass of 1.7 kg and both use copper as the base material, this difference can only come from improved heat transfer at the surface and better heat transport inside the copper.

The tests demonstrated that the LN2 container can easily handle the Core i9-14900KF with P-cores clocked up to 7.5 GHz, consuming 600W of power. With a heatsink base temperature difference of 11°C compared to the Volcano LN2 cooler, compared to a total heat up of only 9°C(!), the AI design proves to have the potential to carry more than twice as much power for the same base temperature. The AI design therefore passes the tests with flying colors, and with a huge margin left on reaching higher powers.

Push the boundaries of thermal management

This pioneering project was initiated at the request of SkatterBencher and ElmorLabs, both leading authorities in the overclocking community. Their expertise and insights were instrumental in guiding the development process. Their ambition aligns very well with our commitment to pushing the boundaries of what is possible in thermal management. This revolutionary LN2 heatsink is a clear example of our dedication to leveraging our technology to create groundbreaking solutions. We are thrilled to introduce this world-class product and the new standard it sets in the industry. Yet, the current design is only the starting point of the collaboration. While preparing the supply chain for the commercialization of the product, we are already preparing additional variants. At the top of the target list is to go beyond the 2000W mark in physical tests. To be continued!
