Hi, I've done some research about leak testing the water cooling system. I haven't gotten my components yet. But i'm wondering if I could possibly setup my water cooling loop without putting the computer parts. Like just the case and the cooling. I've been suggested to put paper towel on top of the components and check once a while but I just wanted to know if I could run the leak test without putting the computer parts. Thanks

Update: Because I'm getting a new case so I'm not worried about having no computer to use. Even though distilled water is not conductive but i'm kinda scared of my components got in touch with water and since I'm a total newbie in water cooling. I think I need to be extra cautious about leaking issues.

You CAN do that, but it wont help much. You still need all the components attached to do a full test, and when trying to install the rest of the components you risk creating new leaks, and causing more havoc than good as the tubes and water blocks will get in the way. I would just put it together and pack it with towels, it is safer overall.

The best way to do the leak test is to put the computer together with all the parts so that if there is a leak you can fix it. Just doing the loop without components still means you have to reassemble the whole thing after and risk leaks again.
The best way to do this is to run the water loop without running the motherboard and components so that is there was a leak and water came in contact with a component there would be no power applied to the part and you would not have any damage as it would give you time to dry it up.

The way to do this is to take the motherboard main power connector out of the MB and insert a jumper into the green wire hole and any black wire hole and that will activate the power supply and power up the fans and pump with anything connected to the motherboard receiving no power.
I've had several occasions where I've had a leak and liquid got on the video card and because there was no power to it there was no damage and I was able to dry the liquid , fix the leak and then finish with the build and power up.
