Question 2 pin FAN cable in front header?

[piechockidocent9]

Hey yall, gotta quick question about this. I'm assembling a pc for cousin in Krux Leda case he picked and it has this cable I have no clue where to plug or what it does. I looks like one of the case front panel cables (pw/pled/re/hd) but mb Gigabyte B450 Gaming X front panel section of the manual has no such thing. Should I pit it in place of pwrled or in first two pins from left of any onboard sysfan slot?

A picture or description of cable may help.

Hey'n'thanks for the reply. I'm not so much confured about the mb manual or front panel pinout (though I hate that becasue it's annoying to do with my big hands) I've done that plenty of times. It's this one damn cable I've never seen before, don't have a pic since the pc is already running at my aunt's place but as a reference:

This is what it looks like and all that is needed in 99% of cases except lately cables stopped being colored and are all usually grey/black right?. In Krux Leda it's same excet there is this one additional 2 pin cable like hdd, psw or ressw but it has "fan" on it.

Top of the case looks like this:

There is no fan controll or anything here. Usb-c is a literal dummy plug, a fake. Watched some reviews of the case hoping to find out about that "fan" cable but got nothin' except everyone said the "RGB" button is also a fake doing nothing. Maybe that's connected to the "fan" cable and it's supposed to turn off rgb of the 4 fans that came with the case but if so how?
