Where does it go???

Hello everyone,
I just bought a new motherboard and cpu everything is running perfectly. The only thing is i have the Apevia Xplorer case with the temperature gage in the front. The cord to this is my question where does it go???? its a tiny 2 pin connerctorwith a black and red cord. I have no idea where it goes. if this question is in the wrong category i am sorry. Since it has something to do with the motherboard i think its in the right place.

iirc from my old X-QPACK2, there's a thermal sensor on the end of that cable. Put it where you want to monitor temps. For example, you could tape it to a hard drive, or to a heat sink fin, or position it in the exhaust stream of your PSU.
