Antec Kuhler 620 with PWM Fan?

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?

  1. Hi, the fan of our 620 Kuhler will always run at full speed. Thats why it does not need to be a PWM fan and your Cougar fan does not fit.
    You can replace it with a normal fan, but this would void the warranty. The internal firmware of the cooler will also spin the always at full speed.
  2. Isn't it just possible to connect it to the cpu fan connector on the motherboard?

    No, the Antec setup makes no sense and I have to plug it into the pump, then the pump connects to the mobo. Guess I'm getting rid of it cause the thing is louder than hell.

    Does the pump otherwise not work?

    It works but I have no control over the fan speed relative to the CPU temp.

    Since it's a pwm fan and you would connect it to the cpu fan header (=4pin) on the motherboard should the motherboard controll that fanspeed.
