modyfying the Thermal take Xblower speed controll

I have a thermaltake xblower fanspeed controller. . . it controlls the smart case fan. I tried to modify it so i could plug a regular fan. . . i soldered it to the 12 volt rail of the 12volt molex. The fan spins if the knob is turned to about 80-100%, but lower than that the fan stalls.

I have a thermaltake xblower fanspeed controller...it controlls the smart case fan. I tried to modify it so i could plug a regular fan...i soldered it to the 12 volt rail of the 12volt molex. The fan spins if the knob is turned to about 80-100%, but lower than that the fan stalls. What do I have to do so i can controll it from the minimum all the way up to the maximum setting of the knob? any easy solution? also if i plug the thermaltake smartcase fan...its much more slower...

it's the same exact thing that u did but instead of plugging it into the mobo u plug it into the big power connectors coming from the power supply.
the same connector that u use to plug into the hard drives etc.
 
the power is the same but the direct line to the power supply has the amps u need to do what u want
