Testing Question

[Watashi]

If I leak test a loop by jumping the PSU, and the loop leaks onto my components, will they short circuit? If so why or why not?

If you have them plugged in then yes. The trick is to only plug in the pump when you jump it then any leaks will do no damage assuming you let them dry before putting power through them.

I think so, yes. If something is leaking then a short circuit would the the logical conclusion.

So whenever you are jumping a PSU there isn't electricity running through the mobo?

Just disconnect everything from the PSU except your pump. There wont be any power on your motherboard and GPU that way.

makes sense, thank you

A good trick if something leaks during leak testing without anything powered up is to take the stuff out and displace the fluid and clean it off with 99% isopropyl alcohol.

Should I pour the iso onto alcohol and wipe it?

Depends if it's just a couple of drop you can dab it dry and use some isopropyl to make sure it doesn't leave any residue, but if it's a large spill or something bad it wouldn't be a bad idea to take everything out and rise/bath it in isoporpyl to make sure there is no fluid left at all. After that it would be best to give it a couple of hours to evaporate and inspect the board.

Why is it more effective to use isopropyl alcohol? Is it because it takes off all possible residue?

It's use in industry a lot for cleaning PCB's after soldering joints but also because it flashes away quickly and doesn't conduct electricity. That being said if it's really bad you will want to takeoff heatsinks to make sure no liquid is left in the fins or under it and the chips.

Thank you, all good suggestions. And I will keep that all in mind.

Like stated don't have anything plugged in the psu aside from the pump. I've done it every way and never had any issue even after all my leaks.
