Is there a way to control fans that are hooked up to the motherboard?

[Julian59]

I just got 2 fans and they are both hooked up to the motherboard, I really wish someone could help me with a program or option I can control they're speeds at. If you guys recommend me speed fan I would like to know how to control the speeds and how to know which fan is which.
