The fan header rpm monitoring feature is nice to have and use just as if it were a cpu mounted fan itself. It can be monitored by the bios and shut down the system or prevent it from booting in case of failure. It can also provide an assurance of it's working order to the customer via the rpm's since the pump itself is inaudible. Inaudible to me anyway. The accuracy of the rpm's is as unimportant to me as is the accuracy of the cpu/sys temp's being monitored ...but it sure helps in managing the overall system at a glance.

Thanks again Dave.
