I have a Scythe Kaze Master fan controller, which has a maximum load of 1 amp per channel. I would like to have some basic control over my water cooling pump (EK DCP 4.0), and thought I could rig it up to this. However, this pump draws 1.8 - 2 amps (depending on load/ startup draw etc). This also means I can't plug it into motherboard headers (Gigabyte have 1a max). Since I don't want to overload the Scythe controller, I was thinking of using a relay - the fan controller's potentiometers would hopefully control (but not power) a separate power source for the pump. Alternatively I could buy a different fan controller, but there aren't many that have suitable power delivery AND match my case (brushed black aluminium. My Scythe has a custom fascia). If all else fails I will resort to using a 5v resistor cable (pump starting voltage is rated at 8v, though mine runs fine at 5v). So, does anybody have any experience, thoughts or pointers? (PS I noticed there are plenty of pump + relay guides on the net, but nothing like this. They are all aimed at 240v mains AC pumps that are plugged into the wall).
