I am looking into building my first water cooling system. Going to build most of it myself. I have everything figured out except the fan controller. I would like to have the radiator fan controller by the temperature of either the water or the CPU block. I am looking for some ideas and a general direction to look in. Thanks for all the help.
That is what I want to do. I just need some help in building the circuit. I do not want to buy something that has many fan controllers when I only want to controller one maybe two. I am building this on my server because the fans on it our so loud.
