Abstract
A fan controller is described herein that can be connected to other fan controllers to provide fault information from one controller to the other(s). The fan controllers each control one or more fans. The controllers include signal(s) connected between the controllers that transmit fault information from one fan controller to the other(s) without the involvement of the host processor. Further, the controllers are capable of performing a 'free wheeling' test in which idle fans are spun and tested.
