Thank you very much for your answer.

A question.
By connecting it so the fan will always be running at maximum speed ??

Good morning, I bought a printer and when I finished assembling it I found that the fans that have sent me have only two cables.
The dupont cables to connect them and the connections of the board are three pins.

Is this okay?

If is this OK, Can someone tell me how they connect?

Thanks in advance
