Will a 3pin cpu fan, work on a 4 pin header?

[Khyth]

The motherboard I ordered, has 4 pin cpu and case fan headers, but my case fans, and cpu fan only have 3 pins, will this still work?

Yes. Just make sure you line the connector up to pins 1-2-3 on the header (leaving 4 exposed). Here's a diagram:
