This article covers ASUS ファンレス Chromebox CF40 インテル Celeron N4500プロセッサー搭載.

Overview

The ASUS Fanless Chromebox CF40 is a compact desktop PC powered by an Intel Celeron N4500 processor, running Chrome OS with completely silent passive cooling. Measuring just 124×124×42 mm, this mini PC is designed for environments where noise must be kept to a minimum, such as open offices, classrooms, and public kiosks. Equipped with 8GB of LPDDR4X memory and 64GB of eMMC storage, the CF40 is built for lightweight web-based tasks and cloud applications. The USB-C port supports both Power Delivery input and DisplayPort Alt Mode, allowing connection to a single monitor with power delivered through the same cable. For wireless connectivity, it features the latest Wi-Fi 6 (802.11ax) and Bluetooth 5.2. The inclusion of a Titan C security chip and a Kensington lock slot provides hardware-level protection for business or educational use.

Product Info

Released in 2024, the ASUS Fanless Chromebox CF40 is positioned as an entry-to-mid-range Chrome OS client, typically priced around ¥38,000. It competes directly with similar mini PCs from Lenovo, HP, and Acer in the Chromebox category, standing out for its fanless design and comprehensive security features.

It is not a workstation replacement but rather a low-maintenance, secure, and silent desktop for focused workflows.

Best Use Cases

Education and Library Terminals: Easy to deploy and manage centrally via Chrome Education Upgrade. Fanless operation means no distracting noise in reading areas. Not suitable for students needing Windows-only educational software or heavy computational tasks. Digital Signage and Kiosk Displays: With VESA mounting and 24/7 reliability, the CF40 can power video loops and web-based signage without fan wear. Performance is adequate for 1080p content; 4K video playback is possible but may stutter on complex overlays. Simple Second PC / Living Room Browser: Connect to a TV for web browsing, YouTube, Netflix, and light productivity via the Chrome browser. The passive cooling keeps the living room quiet. Avoid if you need local gaming or video editing. Remote Work Thin Client: Ideal for employees whose daily tools are web-based (SaaS apps, video conferencing, cloud storage). USB-C monitor support simplifies desk setup. However, it lacks the local processing power for large spreadsheets or professional creative software. * Not Recommended for: Developers compiling code locally, graphic designers, gamers, or anyone requiring Windows/macOS software. The limited memory and eMMC storage will quickly become bottlenecks in such scenarios.
