I have just put a costum CPU loop together and I am starting to test it. I have heard that you are supposed to leak test for about 24 hours. So do you really have to test it for that long or would 10-12 hours be enough? Any help would be greatly appreciated.

I honestly don't think it's worth skimping on the leak test, I understand that you'd want to get to use your PC here and now, but it's just not worth potentially losing costly equipment for a little impatience.

Please, let it run for 24 hours and maybe even a little longer.

Hopefully you aren't testing it IN the case with all those expensive components. :p

Here what I did: I put them together, placed them on tissue paper on the floor next to PC, hooked the pump up to my PSU in the case and let it lie there over the next few days while I did what I usually did on my PC. Mind you, this is 3 years ago, fittings have become better and whatnot.

I am testing it in the case because I am using a jumper so that none if my other components are running. I mean I know the tubing is very tight on the compression fittings. So I would like to get the testing done as soon as I can but then again I want to make sure. That's why I was curious if 12 hours would be enough?

So I'm just curious what could occur in 24 hours that wouldn't happen in 12 hours?

I would agree and let it run for 24 hrs. After the 24 hrs you should be good to go. You can never be 100% sure that the system will never leak. I had my system running for about a year when my I couldn't boot anymore. I looked under the hood, and was surprised to see the acrylic on the cpu block had cracked and was dripping slowly onto my video card.

The good news it that after everything was cleaned, and repaired it still worked with no issues.

A leak in your water set up isn't always a death sentence, depending on what fluid you have in your loop :)

That's right! I used non-conductive coolant from XSPC, not sure if they still make it though. This is not always a life-saver, but in small quantities, things might survive.

EDIT: They do indeed still make it, and now it's not even toxic anymore. xD
