because the adapters dont include the sensing wire which i would like to have for my fan controller
And that's your problem. The Antec case fans weren't designed to be used that way.
My question is, "Do you really need a fan controller, or do you just want one?
I have three Antec 900 cases (same type of fans). I discovered that the air flow on LOW is good enough that my temps do not change when I increase the fan speed to MEDIUM or HIGH.
I think you have two alternatives:
1. Get a fan controller that you manually vary the speed, or
2. Get a fan controller that plugs into the motherboard for automatic temperature sensing and speed control.
