Systems with a passive cooling, fanless PCs, passively cooled PCs: Behind this always stays the same thing. These Mini-PCs don t conduct the produced heat via a fan to the outside, but via cooling fins out of thermally conductive metal on the PC housing. The industrial PCs are used in different areas. Since most of the housings are completely closed due to the fanless design, some of the PCs also withstand demanding environmental conditions such as dust or humidity in production halls or in the outdoor field. In combination with an SSD the passive cooling systems ensures a completely silent working environment, which can be of advantage when used as an office PC.
