How do you control fan speeds using SpeedFan? Having trouble....

I've got a DFI Lanparty Ultra D mobo and have a CPU fan, NB fan and Exhaust Fan hooked up to the motherboard sensors. I installed speed fan and I'm able to see the temperature of the CPU, Northbridge, Hard disk etc. I'm also able to see the speeds of the CPU fan, Northbridge fan and exhaust fan.

How do I control the fan speeds? I keep trying to use the speed percentages but nothing changes.. Do I not have something set up properly? Thanks!!!
