Performance and Design
The Intel Core Ultra 7 255U isn’t the most powerful Arrow Lake chip, but its 15W TDP makes it ideal for a passively cooled chassis. Unlike high-performance chips that generate excess heat, the CI675 nano ensures reliable speeds without the noise of fans.
The design closely resembles the older CI660 nano from 2018 but integrates modern technology. Its compact 1.79-liter frame provides enough room for advanced cooling while housing dual SSDs and high-speed DDR5 memory.
A Fanless PC for Modern Needs
With WiFi 7 and Bluetooth 5.4, the ZBOX CI675 nano is future-ready for faster connectivity. It’s built for offices, home entertainment setups, and users seeking silent, efficient mini PCs. Zotac also announced a ZBOX CI655 nano variant with an Intel Core Ultra 5 processor, catering to more budget-conscious buyers.
