ABSTRACT:
The present invention relates to a fan unit used for forced air cooling, a motherboard with predetermined wiring formed as a wiring pattern, disposed on the rear face of an equipment, and an electronic equipment provided with the fan unit and the motherboard. It is an object of the present invention to reliably maintain appropriate forced air cooling at low cost. For this purpose, the fan unit of the present invention measures temperatures of predetermined places in parallel, processes each of combinations of these temperatures, outputs the processing result via lines whose number is equal to the number of the combinations, and maintains the revolving speed of fans at a value suitable for the processing result obtained via these lines.
