Design and build

Most commodity small PCs follow identical design rules – a heat-sink on the CPU with a centrifugal fan blowing over it, all encased in a plastic housing. fit-PC design is radically different – focusing on miniaturization, robustness, reliability and silent operation rather than making the cheapest possible system.

Thermal design

All fit-PCs are designed for fanless operation at the smallest possible form-factor using the most reliable cooling mechanism in existence – heat dissipation through the housing itself. fit-PC3 is no different, but it takes the thermal design a step further –
• Internal passive heat-spreader to eliminate hot-spots.


• Power regulation based on both CPU and case temperature monitoring. If case temperature exceeds a threshold the CPU is underclocked until temperature is back within permitted range. The threshold can be configured in BIOS.

Industrial design


Each part of the metal housing of fit-PC3 is 3D modeled and produced by die-casting for perfect fit. The streamlined design under 1” thick may be misleading – but fit-PC3 is one of the toughest computers on the market – easily withstanding industrial, automotive and outdoors installations.

Embedded grade internals

CompuLab has been making embedded computer-on-modules for over 15 years. We know that using quality parts results in returning customers. All electronic components in fit-PC3 are embedded grade with long term availability and are RoHS compliant. The standard warranty on fit-PC3 is 2 years.
