The gauge that you are referring to in your linked example is a case temperature gauge and not a CPU temperature gauge. Wish I had one built into my case

).
On my computer case (Corsair 'Obsidian' Series 650D) I also have wires labeled as Fan 1 and Fan 2 (along with Fan 3 & Fan 4). If your set-up is similar to mine then each two wire set ending in a small plug comes from the front mounted fan controller (4-position switch) and plug into each individual case fan. They DO NOT plug into the motherboard. There should also be a 4-pin Molex plug (also from the front mounted fan controller) that plugs into your power supply (PSU).
If you want to let your motherboard control the case fan speed rather than using the front mounted fan controller switch, then plug the fan plugs directly into the fan sockets (headers) on your motherboard and adjust your BIOS for fan speed. Do not use those front controller wires at all. Check with your motherboard instruction booklet as to where to plug in the case fans and how to enter and configure the BIOS.
Hope this helps and if you need more help, just ask !.
