Fanless Industrial Computers
A fan is a bearing, and a bearing in a dusty room is a scheduled failure. Removing it removes the intake that pulls conductive dust onto a board, the noise that rules a machine out of a control room or a ward, and the part most likely to strand a machine that is otherwise fine.
Passive cooling is a design decision made at the chassis, not an option added later: the case is the heatsink, so the thermal budget is fixed when the processor is chosen. That is why these machines are specified as fanless from the start rather than converted.
The machines below are the passively cooled systems in the catalogue — embedded box PCs, panel PCs and controllers. Where a build is offered in both cooled and fanless forms, it appears here only when the fanless form is what DuroPC ships.
