Arctic Senza AI 370: A Completely Fanless Mini PC That Mounts Under Your Desk

Zero Fans, Zero Noise, Serious Power

Arctic just delivered something the silent PC community has been dreaming about for years. The Senza AI 370 is a completely fanless mini PC that packs a Ryzen AI 9 HX 370 processor — a 12-core, 24-thread mobile chip with Zen 5 architecture — into a radiator-style aluminum chassis designed to mount directly under your desk. No fans means no noise. None. The loudest component in your workspace becomes your mechanical keyboard.

The chassis design is the engineering story here. Arctic, best known for its PC cooling products, has built the entire enclosure as a passive heatsink. Eight copper heatpipes transfer heat from the processor to the finned aluminum body, which then dissipates it through natural convection. The under-desk mounting position is intentional — hot air rises away from the unit naturally, and the mounting brackets keep the PC out of sight while maximizing airflow around the fins. Arctic claims the system stays under 50 degrees Celsius even under gaming loads, which is genuinely impressive for a fanless design running a 12-core processor.

What Is Under the Hood

The specifications read like a premium ultrabook compressed into a box. The Ryzen AI 9 HX 370 brings Zen 5 cores, an integrated Radeon 890M GPU with RDNA 3.5 architecture, and a dedicated XDNA 2 NPU for local AI workloads. Memory is 32GB of LPDDR5X-8000 soldered onboard — fast enough to keep the integrated GPU fed during gaming and content creation tasks. Storage is a 1TB NVMe SSD, and connectivity includes Wi-Fi 7 and 2.5 Gigabit Ethernet.

The Radeon 890M integrated graphics are worth highlighting. While this is not a discrete GPU, the 890M is the most powerful integrated graphics AMD has shipped, capable of running modern games at 1080p with reasonable frame rates. For a fanless system, that is a remarkable amount of gaming and creative capability without any active cooling whatsoever.

Who This Is For

At approximately $1,400, the Senza AI 370 is not competing with budget mini PCs. It is aimed at professionals and enthusiasts who value absolute silence above all else — audio engineers, video editors working in quiet studios, home office workers who want zero background noise during calls, or anyone who simply cannot stand the sound of a fan. The NPU also makes it interesting for developers working with local AI models who need a quiet, always-on inference machine.

The under-desk mounting approach is practical and elegant. Rather than taking up desk space like a traditional mini PC or NUC, the Senza hides completely out of view while maintaining excellent thermal performance. Cable management runs along the desk legs, and the only visible components are whatever peripherals you choose to connect. For anyone building a clean, minimal workspace, this is about as invisible as a desktop computer gets.
