[SOLVED] Kolink Stronghold - 2 pin connector cable marked "Fan"

[sfield3]

I have a Kolink Stronghold Tempered Glass Mid Tower Case - Black 2 x Fans (one front-mounted and one rear-mounted)
The case has a thin connecting wire with two pins with the word "Fan" printed on it, where does this wire connect onto the motherboard?
The thin wire is similar to the front panel connector wires that connect onto JFP1 (which are labelled: Power LED, Power Switch, HDD LED, Reset Switch)
It is not the front case fan cable as that is a normal 3 pin fan cable which is connected onto the motherboard without issue.

Apparently it is just a switch on the top for controlling RGB, but there is no included module so it does nothing on its own.
