Turn fan control off, that'll run them at full power.
I'd like to also ask, how does this kit ask you to power the pump and fans? My Thermaltake Extreme has the pump getting power from the CPU fan header, and the fans hooking into the pump. You want the pump to be at 100% all the time, I'd also say get an adapter to hook the pump into a 4-pin molex for full speed-operation no matter what, then hook both fans into the CPU fan headers and let the motherboard manage fan speed dependent on CPU temp.
