No clue where this goes

I have no clue where this plus goes at all, the only thing I know is it controls the 2 other fans in the case.

 

Its from a s340 elite case and I am trying to plug it into a z270 strix e motherboard.

Molex connector connects to power supply

Looks like a general 4-pin power cable? They usually plug into a cable on the PSU, not the mobo.

That's a 4-pin molex connector. I think it connects to your power supply for this use, but I'm not too sure. I'm not really good with modern cases.

It's molex, but just remember plugging it in will have your fans run at 100%  all the time

It is a four pin molex connector with two of the pins removed.  Judging from your comments about the case, I would imagine that it is the power connection to the fan(s) in the front of the case.  Just plug it in to a cord from the power supply that has the appropriate connector (male to female) and all should be good to go.
