I have an Antec Kuhler 620 closed loop system on my 3570k. The Antec fan was way too loud and always ran at 100%. I ordered a PWM Cougar fan, and now when I plug it into the pump connector I get no fan movement, The fan itself does work, but I assume it has to do with the Antec connector since it has only 2 pins. Any way I can make this work and still monitor CPU temps/control the fan speed?
