This 8th Generation Fanless PC has moved fanless performance into new territory. The 6-core i7 CPU has performance levels 40% higher than our previous 7th Generation i7 product.

We include high performance DDR4 3000Mhz memory and the latest Samsung 970 PCIe SSDs which have exceptional performance, creating a system that is suited for intense industrial or business use.

The industrial grade case has an extremely robust design. The embedded O-ring gaskets and silicone seals protect the inbuilt system from water spray and dust.

This model features the Gigabyte Z370n Wifi motherboard, which uses premium components throughout. It features include dual intel LAN ports, dual band Wifi, Bluetooth 4.2, near-lossless audio, 3 video outputs (Displayport, HDMI 2.0, HDMI 1.4) and 7 USB 3.1 ports including 1 type-C port.

The product uses a copper block on the CPU that connects to the external cooling fins using heat pipes. The motherboard's chipset is also cooled with a heatpipe. This design enables the product to not need air vents and enables it to be used in dusty/dirty environments. Because there are no moving parts and no air sucked into the case the product has zero maintenance and high reliability.

The internal industrial fanless power supply enables intense 24/7 operation.  No external power adaptor is needed, the PC only requires a mains power lead. Worldwide voltages are supported.

Both the Displayport and the HDMI 2.0 output can display 4k at 60fps enabling dual desktop 4k monitors at 60fps. 3 monitors are supported by using both HDMI ports and Displayport.

An additional 4 x 2.5" SSD or Hard Drives can be added which can be configured as RAID 0/1 pairs for speed or security.

User Access to fast PCIe SSD: The chassis has been adapted so that it is possible to access the ultra fast PCIe SSD that is on the underside of the motherboard.  Simply remove a few screws in the PC's base plate, and once the base plate is removed the SSD can be replaced. The SSD has a thermal pad so that even under extreme loads it does not overheat.



PCIe Expansion Cards Supported: PCI Express cards with 1x PCIe slots can be fitted inside the case enabling varied expansion possibilities.



Configured to your specification

We can create a solution to meet your specific requirements. Other motherboards and CPUs can be installed to make a fanless system matching your requirements. Please get in touch with the contact form, online chat, or give us a call.

If you choose the Windows installation option, as well as installing on the internal SSD drive, so it is ready to use out of the box, we also include a USB memory stick with the Windows installation, so you can rebuild or repair Windows if you need to.

You need to supply your own Monitor, Keyboard and Mouse. Please contact us if you need any recommendations or want custom additions bundled with your order.

Motherboard Technical Specification

See: Technical Specification

Fanless Heatpipe Technology


The CPU and the motherboard chipset are cooled by using advanced heat pipes attached to both sides of the case. This technology provides efficient cooling by transferring the heat to the cooling fins on the outside. As a result you get a completely silent cooling solution that can be trusted. The cooling is so effective that even the Core i7 can be used at 100% CPU load continually without any overheating problems.

The heatpipe cooling of the motherboard's chipset enables stable performance even under extreme loading. Cheaper fanless ITX cooling solutions rely on air cooling of the chipset which requires ventilation slots in those cases.
