no you dont need a 24 test, do a 30 min test with you always eyeing it for leaks, make sure you have a flash light sometimes a single drop of water takes time to build up. if it pass the 30 min test with no leaks then leave it on all night and go to sleep then check in the morning for any leaks. if no water is dropping then your golden

i usually watch my system for 20mins with just the pump running, and if all is good, i power it on

Yeah, there really is no need for 24 hours. I believe I left mine for 2 hours my first time and then only maybe 5 minutes after maintenance and whatnot. There's also absolutely no reason to build outside of the system!

Heads up on the kit, the hole/thread for the barb on the reservoir/pump (assuming they haven't changed it) was actually stripped on mine and caused it to leak. I siliconed it and it's been just fine, but just a heads up.

I check for leaks for 20 minutes, then check back often while the pc is running for a week. Then I check once a week mainly to make sure the water level is good. The only leaks I ever find are the ones that happen instantly.

ekk um i HOPE your using distilled water. i would suggest that you ground your pc and lay some paper towels in the pc so you parts dont get wet. but in the case something happen and parts go wet just dont turn on your pc for 12-24hr ( better safe than sorry ) tap dry and thing that go wet and let it air dry.

Is the GPU in the loop? If not just don't have it in there.

If it is, or otherwise needs to be in place due to hoses, you should put a small container on the back of the graphics card to catch any drips. The drips will fall off places where the hose bends or from around the block ports.

If drips do get though...just dry them off and don't worry about them. Nothing special is needed. You probably have a higher chance of lightning striking the GPU than water hurting it when it is powered off. I've ran graphics cards and mother boards through the dish washer to clean them.

As for the test time...on a new setup I will watch it really close for about 15 minutes...then come by once an hour or so until bed time...and then check it in the morning. Then I power it down until I get home again...then I watch it close for another 15 minutes...and then I certify it leak tested.

Why not? how do you think they are cleaned in the manufacturing process?

I've never had one come out not working...or at least one that was working when it went in.

Note: I use the shortest cycle and only a slight amount of dish detergent.

Did you realize you said no need for 24hrs then went ahead and said to let it run overnight?

I've never run my loop overnight for that purpose. Run it for a while, hour if you want to. After yer sure you've got it bled, take some tape and mark the res, draw a line to show level while off and on. If it drops below in the next few days ya know you have a leak. Just double check to make sure you've tightened everything, cuz ya know that's how most leaks occur, thru user error. Also, the process of bleedin is when you will typically find any leaks so pay attention.

**Almost forgot. If you do run yer loop overnight and it does leak while yer sleeping that is very bad too. Your pump will fry and any electric problems from your loop draining itself all over your case.

It's not recieveing power so it won't damage it.

Similar to if you drop a phone in water while it's off, it'll be fine if it dries fully. But if it's powered on, there's a good chance it's dead.

What i do is i power the pump without the rest of the system (psu jump, unplug cpu pins and 24 mins from mobo and all video cards)
place paper towel under all fittings and under radiator
watch closely for an hour or two then
yes
i leave it overnight if nothing is leaking

check the paper towel (or toilet paper works too) for signs that water dropped onto it and dried up. it should deform the shape somewhat.

honestly after assembling, youll probly find you have enough confidence that you put it together securely. The most common leaks i see around here is from damaged radiators/ defective swivel fittings.

What everyone else said ^

My belief is that any major leaks will happen within a few minutes of the system turning on. If you dont see any water anywhere (check around the fittings mostly) after an hour then you're fine.

For me, I measured the tubes and then built the setup on my bed. Let that run as I did cable management in my case. By the time I was done, at least 30mins had passed, I went to check for leaks, and there was nothing. Leaks would have been pretty apparent on my bed sheets also.

Installed the setup, let it run again for a quick 5-10 mins (used needle nose tweezers to jump the green and ground cables on 24pin connector) before I powered on my system.

Once a week or so, I'll take my flashlight and take a look through the window and around the bottom for signs of leakage.
This is mainly since people have reported that the reservoir I use may develop leaks :\

if you are using the 7/16" tubing thats comes with the kit youll be great using the barbs that come with it. Dip ends of tubing in hot water to get them over the barbs easily. You dont need to use clamps either as the fit is leakproof

if you want to use 1/2" tubing then id recommend using decent clamps. the clamps that come with the kit are pretty crap and i guarantee youll have leaks. i use some screw in clamps on my kit with 1/2" tubing works a treat.

oh and after first month, unscrew the waterblock and clean inside it. there will be gunk

That's what I'd do.If it lasts 30 minutes without a significant leak, then you will only have to worry about slight leaks that will take quite a while to become noticeable.

Make sure you cover all of the fittings with paper towel, in case there is a small leak.

As long as you are using distilled water, anything that the water contacts just needs to be dried, and then everything will be fine.

Yeah, keeping it simple seems to be the safest plan. Just use barbs and clamps or compression fittings.

UGHHHH.
The fluxes are cleaned with Deionised water or Isopropyl alcohol in a ultrasonic bath cleaner NOT A DISHWASHER WITH A DETERGENT

Leaks while setting up the loop? It's unlikely that a loop will leak once it's fully tested, right?

Heh, once deionized water hits anything...it is no longer deionized. So water is water. Granted it will still be better than my tap water, but it isn't like it is going to make a crust on the PCB that could cause a short.

Plus it's not like I take my motherboard out once a week and give it a bath either...but if I get a really dirty mother board there some times is no other way. I've seen some that have had the PCI slots packed with dust...even saw dust on a couple occasions.

I just put in the bit of detergent to remove any thermal paste, cigarette dust (man that crap sticks on hard), or glue from unwanted stickers (if there are wanted stickers they will need to be covered up with good tape). It doesn't take much. If it was just normal dust it isn't needed, but it hasn't hurt anything. You just have to be sure it is dried well before you power it up (and remove the CMOS battery...but I even forgot that once and the board was still OK)
