Old fan new computer?

[Javs]

Hi there! Today I started cleaning my pc when I remembered my parents had an old and broken PC from the 90's. So I opened it for fun and I found it had some shit I could make use of, including the system fan. The thing is, the conector of the fan (4 pins-1 pin like covered up by a plastic I removed) doesn't do anything when I plug the thing to the motherboard, and I was wondering if anyone knows a way of making it work, cause you know, more air flow is always better

move the ground wire over one pin

wait now that I look at it you have to flip flop both the red and black and that should do it

Ty! Instead of doing weird things in old pins, looking at the image, I just turned the conector and move it two pins to the side, and it works!
