You're doing what?! For two years I've run my K3s in NAQP at 100 watts with high duty cycle. The fans seldom turn-on and the PA is barely warm. If you can out-design N6KR, I'd be amazed.

I am upgrading both fans to a fan with higher CFM output. Last night I hooked both fans up to the KPAIO module to test and see if they will work. When I am on fan power level one, the fans try to but are unable to start up. I have to bump them to start them spinning. Power level two has no problem spinning them up. When I went to power level four and then brought the power level to one, the fans did not have any problem continuing running. The fan specs can be found here http://www.sundialmicro.com/ipcqueen_dc_fan_606010_ball_bearing_3pin_2033_1199.html. Is there any components that I can add in line to provide the necessary power to start the fans up at power level one?
