I am setting up a custom water loop using an xd5 pump ,finding it hard to find out if, what I want to do is run the pump pwm line from my strix rz5700xt fan header on GPU since I can set this to run off GPU temp and power the pump from the molex connection,a few I asked said it would draw too much power from the gpu I thought the pump draw was from molex and pwm line was for rpm and signal ,any help would be nice
