As AI workloads demand more processing power in increasingly smaller form factors, thermal management has become one of the most critical factors in system design. Conventional cooling solutions consume considerable board space, restrict component placement, and generate significant vibrations that introduce acoustic compromises that become more difficult to mitigate as devices become more compact and powerful.
Ventiva's ionic cooling solutions offer quiet, vibration-free thermal management in a compact, modular form factor that frees up motherboard space and expands design flexibility for system designers. Through this partnership, Ventiva and ASUS will explore the potential role of Ventiva's ionic cooling in future ASUS AI system architectures, assessing where the technology could have the greatest design impact.
As part of this collaboration, Ventiva has unveiled an ASUS NUC demonstration platform. The system illustrates the direction of the collaboration and provides a real-world platform for evaluating the possibilities of thermal architecture in compact, AI-enabled designs.
“Thermal management has always been treated as a component-level decision. What we’re seeing now, and what this collaboration with ASUS reflects, is that it’s becoming a platform architecture decision. How you cool a system determines what you can build,” said Christian Schlachte, Director of Product Management at Ventiva. “We’re excited to work with ASUS to demonstrate what the shift to a cooling-first architecture makes possible.”.
“Thermal architecture is becoming an increasingly important part of the design of next-generation compact AI systems,” said Alex Gilpin, senior director of Advanced NUC Engineering at ASUS. “Our collaboration with Ventiva reflects a shared interest in exploring new approaches that can help shape future ASUS NUC and mini-PC designs. This initial phase focuses on prototype development and technical evaluation as both teams assess the possibilities.”.
Technical Background: Ventiva Ionic Cooling Technology.
Ventiva's all-electronic, solid-state heat transfer technology harnesses the principles of electrohydrodynamic flow (EHD) to move ionized air molecules within an electric field. This innovation in ionic cooling moves air without mechanical fans, creating a quiet, vibration-free airflow. Unlike traditional cooling systems, Ventiva solutions scale easily, integrate seamlessly into system designs, and enable airflow configurations that were previously impossible.
Ventiva's thermal management subsystem is thin, lightweight, and highly modular, designed to adapt to a variety of system architectures. It comprises a self-contained air blower device, a fin stack, and a vapor chamber or heat pipe, providing optimized cooling efficiency of up to 1.1 CFM per device. The air blower devices can be positioned alongside heat sources, such as SoCs, memory, and power supply components, without the space limitations imposed by traditional fan-based cooling.
Frequently Asked Questions
: What is ionic cooling and how does it work?
Ionic cooling uses electrically charged particles to move air without the need for rotating parts. Ventiva's ionic cooling technology harnesses the power of a tiny plasma field to move air particles, providing targeted cooling that removes heat from specific areas of a system. The result is a solid-state cooling solution with no moving parts, no vibration, and no noise.
Does ionic cooling produce noise?
No. Ventiva's ionic cooling technology has been tested in anechoic chambers, showing a sound pressure level of less than 15 dBA. This is an imperceptible level that barely exceeds the background noise level in an anechoic chamber.
How thick are Ventiva's air-blowing devices, and where can they be placed in a system?
Unlike traditional fans, which are top-in/side-out airflow devices, Ventiva's ionic cooling module doesn't require an air gap to draw in air; it's a side-in/side-out device that makes better use of space. This allows for an internal height of just 5 mm for the customer application, enabling thinner product designs.
Why is ionic cooling particularly well-suited for AI workloads?
AI workloads generate intense, concentrated heat in the processor, as well as in memory and accelerator components operating in close proximity to the SoC. Conventional cooling solutions struggle to address these distributed heat sources without adding bulk and noise. Ventiva's modular approach allows each thermal zone to be cooled independently and precisely, so the system can maintain the kind of continuous, high-performance operation that AI applications demand.
