Question I have two case fans that are 3 pin but my motherboard only has one 5 pin connector

[GeorgeCZ75]

There is only one fan connector in my motherboard and they are for 5 pin fans. I have a J3C2F motherboard that was pulled from a Dell Optiplex. Two case fans come with my case but they are 3 pin and I don't know which adapters to buy in order to make those two case fans connect to the motherboard.

So I can plug in a 3 pin fan into a 4 pin port/connector?
