alright i got my new stuff in today
TT armor case
abit an8 ultra
6800 pci
550psu
a64 3500+ venice

orderd my cooling kit from dangerden but i have a question about leak testing
should i design my loop then take it out of the computer and fill it up and leave it running for 24 hours or should i leave it hooked up to the cpu and vga while its leak testing im almost positive you have to let it pump the loop for 24 hours or can you just leave the loop filled up without running the pump? thanks in advance

What I plan on doing to my new WC setup is to do a mock up of it and then take it out and run the leak test.

Just like they do on American Choppers (OCC) :D
 
yea thats what i thought would be the safest incase there is a leak
but i wasnt sure of the right procedure
 
Install parts, cut tubing lengths for loop, remove parts, connect everything, fill and bleed with pump for 24hrs, re-connect
 
Yea, I was wondering the same thing earlier today. Talked to a friend who's done it and that's what he told me ;)
 
I'm at work and my father is at home watching mine leak-testing right now. I did what n64 man is suggesting. Mounted the waterblock on the cpu, installed rad/pump/reservoir, cut the tubing, disconnected IDE drives, slid out mobo tray.

It's everything set up so all I have to do if it passes the test is apply some arctic silver slap it on the cpu and reinstall all the IDE devices.

Good luck!
 
Another way to do it, that I prefer, is to setup your loop inside your case and all, but instead of hooking up the pumps to your regular PSU, get an old AT power supply and hook them up to that. Then, you can leak test without having to disassemble and reassemble, which could potentially cause a leak :)

but how do you power up the PSU without having it connected to a mobo and power switch?
 
there is a way to fool a PSU into thinking there is a mobo there by shorting out two of the pins. Not sure which ones but a google search can find out.

How I've leak tested in the past. was to assemble the parts inside, take them out, re-assemble and run for 24 hrs. re-install it and then leak test it again without turning the computer on, just incase there is a leak from the re-install.

the best way to do it is to build your system so you don't have to take it apart. But that's in a perfect world and that doesn't always apply to every situation. the more times you take apart your loop the more chance there is for a leak. But a couple times doesn't really matter.
 
so technically the computer has to be running in order to leak test but away from the water components..... So what about the cpu... How am I supposed to keep it cooled while leak testing. You say to make your fittings first (mounting the blocks), that required removing the air cooled HS. I'm just a little confused now.

I will be having a 420W PSU as a spare soon (ordered a new 600W), but I don't want to "short" anything which will do perminant damge to it....
 
I guess I am the Lone Ranger, but I test mine inside my case with everything installed. Although I use a seperate power supply coonected to my AC molex. I have so much faith in the fittings that I never considered doing it any other way. If I had experienced a leak I would have let everything dry for 24 hrs. However, I wouldn't use this approach with clamps.
 
well i have 4 computers here in the nerd shack (my room) what i think ill do is hook up my loop bleed it and everything then take the side off this old crap tastic dell im using for a file server and run one of the power plugs to my pump and let it run like that for 24 hours before i put it in my new rig

Green wire (PS_ON) to any black (ground) wire on the main ATX connector.
But that was my point with using the AT power supply. They don't have soft-power, they have a power switch that is hard wired to the AC input of the supply. When you hit the switch, regardless of what's connected, it will turn on ;)
 
I think I'll revise my leak testing method :D

I'll probably set it up all in the case and use an external DC power supply to run my MCP650 so there would be no need for the use of the PSU while leak testing.
