[SOLVED] What do I set my fans at on my mobo?

[cbrocks06]

so it says pwm/dc and im not sure which one i should use? i have 2 fans that came with my case that is not connected to my mobo and then i have 4 fans that are plugged into the mobo. Im just confused on if i should use pwm or dc??

PVM for 4 pin fans and DC for 3 pin fans.
