Selection Guide
Fanless or actively cooled? Start here.
A desktop mini PC is fine on an office desk. Move it onto a 40 °C factory line covered in fine dust, and it won’t last the week. Industrial mini PCs are built for that shop floor — and the first decision is how they’re cooled.
Fanless (sealed chassis)
No fan means no airflow — and no airborne dust, metal particles or moisture being pulled across the board. That’s why fanless machines survive where a fanned PC shorts out or overheats.
- Dusty, wet or vibration-prone sites
- Silent or 24/7 unattended operation
- Wide temperature down to −20 °C
Active cooling (with fan)
A fan lets the CPU sustain higher load for longer. When the workload never stops — vision processing, multi-screen operator stations, continuous data crunching — active airflow buys you headroom.
- Machine vision and image processing
- Multi-screen operator stations
- Sustained, high-CPU-load workloads
Two more specs worth checking before you buy: how many COM ports you need (RS-232/422/485 is how PLCs, sensors and card readers plug in — 2 ports for a light gateway, 6 ports for a full control cabinet), and whether you need wide-voltage input (9–36V DC runs straight off industrial power without a stable mains supply).

FAQ
Common questions before you buy
Fanless or actively cooled — which do I need?
Choose fanless if the unit sits in dust, vibration, moisture or runs 24/7 unattended — no fan means no airflow, so no dust gets pulled across the board, and there’s no fan bearing to fail. Choose active cooling if the workload is sustained and CPU-heavy (machine vision, multi-screen operator stations), where a fan gives you more sustained headroom.
How many COM ports do I actually need?
Count the devices you’ll connect: PLCs, sensors, barcode scanners and card readers all use RS-232/422/485. 2 ports suit a light edge gateway; 6 ports suit a full control cabinet or multi-machine cell. Our range spans 2 to 6 COM ports across the H-series.
What does "wide temperature" (−20 ~ +60 °C) actually mean?
It’s the ambient temperature the unit is rated to run in. Standard office PCs are rated for roughly 0–40 °C. A wide-temperature model keeps working in an unheated kiosk, an outdoor enclosure, or a machine bay that runs hot — no air conditioning required.
What is wide-voltage input (9–36V DC), and do I need it?
Wide-voltage models accept a range of DC input rather than a fixed supply. That lets the PC run straight off industrial power, vehicle batteries or a UPS without a stable mains supply. Select models (like the H4 12th Gen) support 9–36V DC input.
Can you customize or build to my specification (OEM/ODM)?
Yes. HYSTOU offers OEM/ODM customization — custom I/O, branding, enclosure, BIOS settings and pre-loaded software — with factory-direct supply. Share your requirements and we’ll quote a configuration that matches.
