CPU and GPU cooling

post #1 of 9
Thread Starter 
Hello everyone,

My first water-cooling build is due to arrive in the next couple of days, and I was wondering about something to do with the leak test. I know I don't have to have my CPU in the loop, just the CPU block, but what about the GPU?

I am water-cooling my GTX480. When I run the 24 hour leak test, do I run it with the graphics card connected to the water block? (And what happens if it leaks?!)

Thanks

When I leak test, I always install the water cooling components onto the hardware in my computer as though they were ready to run. Then, I connect only the water cooling components to the psu, leaving everything else (CPU, GPU, Mobo) unplugged for the leak test. Just make sure you put a healthy amount of paper towels underneath every water block in case of leaks.

I make sure to do this in the morning so that I can check it throughout the day for leaks and bleed the bubbles out. If the paper towels are still dry by the end of the day you're clear for takeoff.

Leak testing the components outside the computer, then installing them only leaves more potential for leaking since you're moving everything around.

It's up to you. I would just install everything and use the PSU jump-start method to fill and test your loop. Put some paper towels under potential leak points just in case and you should be fine. Even if you get water spilled on your components, just give it some time to dry. No harm done.

Edit: ZombieAttack covered it all and beat me to it. +Rep for that.

when i setup my loop i installed it all in my pc you will need to hook up your gpu block to get a real leak test done. Just when you power it only plug power into your pump nothing else and if you wanna be extra safe you can take and put paper towels in areas where it might leak like around barbs.

Thanks everyone. So it is possible to run a GPU block without the GPU actually being plugged into it?

What I think I'm going to do is this:
The CPU, GPU, RAM and MoBo are already with me. I am expecting the water-cooling parts to arrive tomorrow so I'll start work on my loop then.

Problem is, my case and PSU won't be with me till Friday or even next week... do you think I could set up my loop and run it using a random PSU I have lying about here?

Thanks

Probably.

If I were you I would wait for the case so that you can mount everything you have inside it during the leak test. That way you can use the paper towel method and get the correct sizing for the tubing figured out.

Agree with all the above info, and it is better to set it up in your case so you can get all the tubing figured out, no point in wasting
Are you using barbs or compression fittings?
You shouldn't have any problem running with your random PSU, look up how to jump one and you should be good to go!
