partaker I31-J1900-8G240G desktop PC 8GB DDR3 240GB SSD

Fanless industrial mini PC for automation

This partaker I31-J1900-8G240G desktop PC 8GB DDR3 240GB SSD is a fanless industrial mini PC built around an Intel Celeron J1900 quad core 2.0Ghz processor. It ships with Windows 10 Pro, 8GB DDR3L memory and a 240GB SSD. The aluminium alloy case doubles as a heatsink for silent operation in kiosks, advertising machines, electronic whiteboards and automation equipment.

Installation and common pitfalls

The unit mounts via its compact chassis and connects through DC-IN 12V power, dual Intel i211-AT 10/100/1000M LAN ports, HDMI, six COM ports (COM1 and COM2 selectable between RS232 and RS485), USB3.0, five USB2.0, audio jacks and a Mini-PCIE slot with embedded SIM slot for WiFi, 3G or 4G modules. Verify serial-port pinouts and voltage levels before wiring RS485 devices, and confirm the Mini-PCIE card height clears the internal bracket.

Sustained-load thermal behaviour

Passive cooling relies on the all-aluminium enclosure to dissipate heat from the J1900 and chipset during continuous duty. Under prolonged full-load scenarios the CPU will throttle to stay within its thermal envelope, reducing compute throughput compared with short bursts. The watchdog timer can reset the system if a thermal event causes a hang, but sustained high utilisation will run warmer than actively cooled alternatives.
