Automatic pause at Pump failure over ATX Motherboard Fan Header
I'm planning to upgrade my 3D printer hotend to a water cooled one, for this I'm using a pump from Aqua Computer which automatically stops on failures like a "kinked tube" (geknickter Schlauch). Now the feature I would like to request is that repetier server checks the rpm of a fan header (where the rpm control of the pump is connected to) and automatically pauses the print if the rpm goes to 0. This could save the print and could prevent a clog in the hotend or (even if it is unlikely) loosening of the tubes because of the heat traveling to the entire water block.

just make it pause on rpm instead of a digital pin. As written it triggers pause with out of filament message, but you can easily change the message.
If firmware measures it and sends a message on failure it would be even easier as we have a parser to act on data send in gcodes->advanced printer configuration.
