I seem to have a problem...I am ready to leak test my cooling setup, but can't seem to get the pump going. I have my PSU plugged-in and only the pump connected to it. It won't power...do I need the MOBO connected? Does the PSU get some sort of signal from the MOBO? Is there a danger in connecting things up without everything plugged in? The computer is stripped right now and all I want to do is power the pump. I have a DD-D5 pump. How can I get this going?

Thanks for any help!

OK mate it is pretty easy to sort this one out. The mobo does usually need to be connected to get the PSU to fire but as always there is a way around this and all you need is 1 little piece of wire. A you can see in the FAQ provided by SpookedJunglist you only have to do a very simple mod. All it is; is connecting the green wire to any black wire on ya 20-24 pin socket and it will fire up. As always be careful playing with electricity especially if you are ever giong to open up the PSU unit itself. This is a fairly safe mod and have it unplugged of course for extra safety so you know you will not get a jolt or a spark if this worries you. Even when plugged into a wall there is only 12V and the chances of getting zapped from doing this mod is very unlikely.

Good luck and enjoy

Excellent! Thanks...just what I was looking for. I was starting to get a little worried as I had filled-up the system with de-ionized water only to do a leak test. I have to drain the system to get the whole thing in my rig anyhow...so I thought...plain water will not hurt...but I didn't want the water sitting in there for a long time.

I will get on that mod and get her going now!

Thanks!

the whole point of leak testing is to leave it fully assembled (minus the actual PC components) to ensure that there are no leaks - if you take it apart and set it up, it basically defeats the purpose of leak testing the system...

Agreed. I don't understand why people put together a system, "leak test" then take it apart again, then install into the case and wonder why they now have leaks after they leak tested it.

I, Personally, leave my PC completely assembled when leak testing,...parts and all. I use rubber bands to affix blue shop towels to all the joints. If there is a leak, the towel picks it up, and it turns a darker blue color. Just make sure you have NO POWER connected. It's easy enough to clean liquid off a mobo or a vidcard, bu if it's running, you can say bye bye to your precious rig.

i do the same thing - basically, but i always take out the motherboard and video card - thats too much cash to risk, and it doesnt take much time to pull the stuff out, leak test, and then toss it back in the rig and attach the blocks

I'm not concerned about the hose connections. I only have to take apart the connections at the reservoir to get the system installed. I would be more concerned about the o-rings in the water-blocks for leaks. That is where I feel the need is for me in leak testing. Besides...I wasn't asking for an opinion on how I put my system together.
