3 Pin fan on a 4 Pin motherboard connector?

[Charnondall]

Just got my new motherboard and ive noticed all the fan connectors on it are 4 pin. I was wondering can i use some of my old fans that are 3 pin on these or am i stuffed and need to get some new ones?

3-pin fan connections will work normally. The 4th pin is for controlling the fan speed. But obviously your fan needs a 4 pin/wire connectore to be able to be controlled via the mobo and software.

If you do not care about that then use the 3-pin fans you have.
