Founded in 2020 and headquartered in San Jose, California, Frore developed a fundamentally new approach to thermal management: silicon-based micro-electromechanical systems (MEMS) that move air through ultrasonic vibration with no moving mechanical parts. This technology directly addresses one of the most persistent constraints in AI hardware and consumer electronics—how to remove heat from increasingly dense chips without fans, noise, or mechanical failure points.\n\nFrore's AirJet chips integrate directly into the PCB or device chassis and can be tiled to scale cooling capacity for different thermal envelopes. The technology is applicable across a wide range—from thin laptops and tablets that currently rely on passive cooling to edge AI inference hardware, autonomous vehicles, and data center accelerators. NVIDIA CEO Jensen Huang publicly encouraged Frore to expand into data center applications, a significant market signal. Frore's solid-state approach also offers advantages in reliability, acoustic performance, and form factor that conventional fan-based cooling cannot match.\n\nIn March 2026, Frore Systems closed a $143M Series D, bringing its total funding to $340M and pushing its valuation to $1.64B—joining the unicorn club. The round reflects growing investor confidence that thermal management will be a critical bottleneck as AI chip power densities continue to rise. With Jensen Huang's endorsement and a clear path into data center cooling, Frore is positioned to become a key infrastructure supplier for the next generation of AI hardware deployments. ## Frequently Asked Questions ### What is AirJet and how does it work? AirJet is Frore Systems' solid-state active cooling chip that uses ultrasonic vibration of microscale membranes to move air and dissipate heat—no fans, no moving mechanical parts. The chips integrate directly onto a PCB and can be tiled together to scale cooling capacity, making them suitable for everything from ultra-thin laptops to AI inference hardware. ### Why is solid-state cooling important for AI hardware? AI chips are becoming denser and hotter, and traditional fan-based cooling is reaching its limits in thin devices and increasingly problematic in high-density data center configurations. Solid-state cooling like AirJet removes heat more reliably, more quietly, and in a smaller form factor, which is critical for edge AI devices, autonomous vehicles, and next-generation GPU systems. ### What markets is Frore Systems targeting? Frore initially targeted consumer electronics—thin laptops and tablets—but has expanded its roadmap to AI inference hardware, edge computing devices, and data center accelerators. NVIDIA CEO Jensen Huang's public encouragement to move into data centers signals that hyperscalers see AirJet's solid-state technology as a compelling solution for next-generation GPU cooling challenges. ### How does AirJet compare to vapor chamber cooling? Vapor chamber cooling is passive — it spreads heat across a larger surface area for a fan to dissipate, meaning it still requires an active fan and cannot eliminate acoustic noise. AirJet is active solid-state cooling that generates its own airflow without any rotating mechanical parts, enabling completely silent operation, longer product lifetimes (no fan bearings to fail), and form factors too thin for vapor chambers to function effectively. ### What does Frore Systems' roadmap look like for data center applications? Frore has publicly communicated its intention to enter data center AI accelerator cooling markets, encouraged by NVIDIA CEO Jensen Huang. The roadmap includes AirJet variants designed for GPU cooling in dense AI inference racks where conventional fan cooling creates airflow challenges and noise requirements for certain deployments. ### How much has Frore Systems raised? Frore Systems raised over $100M in funding, including a $80M Series C round. Investors include major technology and semiconductor-aligned venture funds. The company has achieved design wins with laptop OEMs and is working toward larger-scale applications in AI edge and data center hardware. ### What is the power consumption of AirJet? AirJet Mini consumes approximately 1 watt of power while dissipating up to 5 watts of heat, providing a favorable cooling-to-power ratio for edge AI devices. In thin laptop applications where thermal headroom is critical, the combination of active solid-state cooling and low power draw enables higher sustained performance compared to passive cooling or traditional fans at the same thermal envelope. ### Who are Frore Systems' design win customers? Frore Systems has achieved design wins with major PC OEMs including integration in thin-and-light laptops. The company has been recognized as a DARPA collaborator on next-generation thermal management challenges, signaling defense and government application pathways beyond consumer electronics. ## Tags ai-powered, b2b, infrastructure, saas --- *Data from geo.sig.ai Brand Intelligence Database.
