Is it possible to control the radiator fans from the h100i using the cosmos 2 fan control interface? The h100i fans connect directly to the pump and use some kind of software to adjust there speed. However, I don't want software, I want to control it with a physical button that is offered on my cosmos 2 case. the problem I am encountering is that the fans on the rad use four pins, but the fan controller supports only 3 pin fans. I would replace the fans with the new one I got from corsair since they are three pins but they are made for airflow, not pressure, and it means I would not be able to use the speed adjust on the fans I replaced it with. Would a simple converter from 4 pins to three pins do the job? If this works, is there a cable to fuse two four pins into a single three pin? Also, by ignoring the software corsair provides, the pump is not going to stop running right? there is an additional single pin conected into a three pin header on the board in form of a three pin, (Only has single pin though), however, there is also a sata power connector connected directly to the pump, along side the single pin.
