Fanless Industrial Mini PCs
Rugged, wide-temperature Mini PCs with zero-fan passive cooling and rich industrial I/O — built for factory floors, automation, and 24/7 edge deployments.
WHY FANLESS
Engineered for reliability, not compromises
01
Fanless Passive Cooling
All-aluminum chassis with zero moving parts — silent, dust-resistant, and vibration-proof for continuous operation.
02
Wide-Temperature Operation
Industrial components rated for operation as low as -20°C on select models — built to run reliably in unventilated enclosures, cabinets, and harsh environments.
03
Rich Industrial I/O
Native COM (RS232/422/485), GPIO, CAN Bus, and dual-LAN connectivity for direct sensor and machine control — no adapters.
04
Built for 24/7
Fanless passive cooling and an all-aluminum chassis mean fewer failure points for around-the-clock operation.

FAQ
Fanless Industrial PC FAQ
How does HYSTOU's fanless design prevent overheating?
Our fanless Mini PCs use a chassis-as-heatsink design: the aluminum housing dissipates heat passively, so there is no fan to wear out. This removes the leading cause of mechanical failure, reduces dust ingress, and enables silent operation — important for medical, lab, and AV environments.
What does wide-temperature operation mean in practice?
Our industrial Mini PCs are rated for wide-temperature operation down to as low as -20°C depending on the model — see the comparison table. That means reliable operation in unheated warehouses, outdoor enclosures in hot climates, and inside machinery cabinets where heat builds up.
Can these Mini PCs run 24/7 without failure?
Yes. A fanless design removes the fan — the leading mechanical failure point — while an aluminum chassis radiates heat and wide-input DC power keeps the unit stable around the clock. This is a proven platform: HYSTOU has built industrial PCs since 2013, and across 48,473 units shipped in 2025, only 336 were returned for service (a sub-0.7% field return rate). Ask our engineers to configure the exact components for your duty cycle.
Which model is right for my application?
For entry-level signage or gateways, start with the H3 or K4. For multi-COM industrial automation with GPIO and CAN, choose the H4T. For high-performance edge workloads and multi-4K displays, the H6 12th Gen or H6 i7 are ideal. Unsure? Our engineers can match a model to your exact spec — contact us for a free consultation.
Do you support OEM/ODM customization?
Yes. We offer CPU/RAM/storage configuration, BIOS customization, I/O and port changes, OS pre-installation, and branding. Contact our team for MOQ and lead time based on your configuration.
How long does a standard order take?
In-stock orders are typically processed within 1–2 business days and shipped in 3–8 business days depending on destination — roughly 7–14 days from order to delivery. Back-ordered items add 4–6 business days of processing; we keep you posted by email. Custom or bulk OEM builds have their own lead time — contact our team for a firm quote.
