Water Cooling Wiring

[xxtigrisxx]

I have watched a couple of water cooling videos on how to install them but what confuses me is that in all of them they've asked to change the wires around for the power supply to the motherboard from the green wire to the black wire so that the CPU does not get fried in the process could i get a deeper explanation on what i have to do and i also have sleeved wiring for my motherboard which would make it trickier i would think?

Thanks need immediate response.

The whole idea around jumping the PSU is so you can turn on the PSU and anything attached without involving the motherboard.
Namely, if you are filling up the loop and using the pump to push water through it, you are not providing any cooling to the CPU or other parts in the loop. So if you turn on the rig normally, your CPU/whatever will burn out since they aren't being cooled. By jumping the PSU (and disconnecting all power to the mobo and GPU) you can turn on the pump without supplying power to the mobo.
The green is the "on" signal for the PSU, the black is just a grounding wire. Connecting them makes a circuit and the PSU turns on.

Their are dedicated tools for jumping the PSU like this.

Or you can just use a paperclip and just use a diagram of the 24pin connector too know which connections to use.

This guy did it wrong and turned on the PSU normally through the motherboard with everything hooked up.

At about 1:19 you can see the board flashing to indicate that the CPU is overheating.
The reason why he managed to kill the pump (and likely the rig) was because he sealed the loop when filling it, the air has no place to go so it stays there and stop the flow completely. You dont seal the loop until the water is flowing smoothly.

So am i just suppose to move the green wire to the black wire to allow myself to fill the water cooling system and switch it back to its original place when im done?

No, all you have to do is make an electrical connection between them, you can do this by putting a paperclip in the right connectors or with that dedicated tool (which is basically just a wire between the two right connections).
