Passive Cooling Meets New Silicon
Zotac has updated its webstore with three new ZBOX mini PCs built around Intel’s “Wildcat Lake” platform. This launch represents one of the earliest instances of passively cooled consumer devices utilizing these specific System-on-Chip (SoC) designs. The lineup includes the CI431 nano, CI451 nano, and CI471 nano.
All three units share identical physical dimensions: a compact chassis measuring 204 × 129 × 68 mm with a total volume of 1.79 liters. Because they are fanless, heat dissipation relies entirely on the passive cooling structure of the case. Internally, each system supports up to 64 GB of DDR5-6400 memory via a single SO-DIMM slot and accommodates an M.2 2280 PCIe 4.0 x4 SSD.
Specs and Power Efficiency Breakdown
The primary differentiator between the models is the processor tier, all manufactured using Intel’s advanced 18A process. Each chip operates with a 15 W base power and a 35 W maximum turbo power envelope, making them suitable for silent operation in small form factors.
- CI431 nano: Features a Core 3 304 processor with five cores (one P-Core, four E-Cores) and five threads. It boosts up to 4.3 GHz and includes one Xe-core GPU running at 2.3 GHz.
- CI451 nano: Upgrades to a Core 5 320 with six cores (two P-Cores, four E-Cores) and six threads. Clock speeds reach 4.6 GHz, supported by two Xe-cores at 2.5 GHz.
- CI471 nano: The top-tier model uses a Core 7 350, also with six cores and six threads but boosting to 4.8 GHz. Its graphics subsystem features two Xe-cores running at 2.6 GHz.
Integrated Neural Processing Units (NPUs) vary slightly across the range, delivering up to 15, 16, and 17 TOPS respectively. All processors include 6 MB of Smart Cache. For users seeking silent computing without sacrificing modern connectivity or AI acceleration capabilities, this tiered approach allows selection based on specific performance needs rather than thermal constraints.

Availability and Next Steps
While the technical specifications are clear, pricing details for the Canadian market have not yet been publicly disclosed in the initial listing. Consumers interested in these fanless options should monitor Zotac’s regional store for cost confirmation and stock updates. The release signals a growing trend toward integrating high-efficiency, passively cooled architectures into everyday desktop replacements, offering a viable alternative for noise-sensitive environments like home offices or digital signage setups.
