Water spilled on gpus (I think)

matt77 · Aug 11, 2013

Hi

So I was installing new 780s yesterday with waterblocks and stupidly forgot to tighten a hose somewhere above (the rad in the upper chamber). Water poured down through the chamber onto the pcb of the first card and probably onto the second card beneath. I'd read that putting cards in rice helps absorb water (I am only using distilled water) and I had jumped the PSU so no current was passing through. I unseated the GPUs, unseated the waterblocks and inspected the cards. I couldn't see any water on the cards themselves, but I guess that doesn't mean no water was lurking under one or more of the components. I threw both cards in a baking tray and poured rice on them, and they've been sitting like that in my airing cupboard for 12 hours.

I don't know if I'm doing the right thing -I'd just read about this method on the net. My question is, how long is long enough to wait? I really don't want to short the cards, but don't know if I am wasting my time since no water was detected on the cards in the first place.

Anyone got any experience of this? Any ideas much appreciated.

Hi, id leave it for 24 hour's then after that the only thing you can do is plug them in and hope for the best.
Hope this helped, sorry i didn't have a better solution.

you put the rice in a sealed container with the card inside. The rice will absorb the moisture from the card, not from the surrounding air. Three days should be sufficient and praying couldn't hurt.

Oh, a sealed bag? Don't have one of them. So what I'm doing is not very good?

matt77 :

its not very efficient, no. It should be sealed up with the rice and video card.

darn it
It's in an airing cupboard though so that's better than room temps

matt77 · Aug 11, 2013

Can i out them in a plastic bag and tighten it? Or does it have to be hermetically sealed?

matt77 :

Go buy a ziplock baggie that a card will fit into. One gallon size should work.

Welcome to the bad side of water cooling.
Sounds familiar, Been there!

Never heard of the rice and IMO it is not necessary, all you needed was a chemical cleaner and force drying agent and you're back in business in minutes vs hours or days.

The problem with a spill like that is the water always gets into the PCI-E M/B slots, and that has to be cleaned as well as the graphics cards and it will have to be cleaned outside the home.

Get a can of CRC QD Electronic Component Cleaner, you can find it at any Auto Parts Store here's what the can looks like at Advance Auto, even Walmart carries it.

You simply spray a light even coat on whatever got wet and seconds later it is dry, it is flammable and not breathing friendly so use it outside the home.

It's one of the only products on the planet that can dry out and clean at the same time the motherboards PCI-E slots.

To be sure you'll have to remove the water blocks from the graphics cards and inspect under them and make sure no water ran under the water block, better to be safe than sorry.

I so strongly recommend CRC QD Electronic Cleaner I now keep a can of it on my shelf, just in case, it will clean and dry any type of coolant corrosion, and will not harm the substrate.

Sorry you're going through this but there's your answer.

Always make sure your G14 O ring fittings are tight, but not over tight to damage the seal, you want them a little snugger than you might think, as tubing counter pressure can and will slightly unscrew them and cause a leak, so check that while you're correcting this problem.

Hmm tried to post but didn't work. just to say that I couldn't find that stuff on the net in the UK. Shame. I'll press ahead with the rice and just hope for the best. Maybe I'll keep it in there for a day and then try them.

Thanks again for everyone's suggestions and help.

Hi all

Just to say that I took the card out of the rice today, cleaned them up, but the water blocks back on and hooked up the system. After a few hours of testing, I plugged them in for real and they work! Both 780s up and running. So huge relief. Big thanks to you for helping.

I've heard of the rice before multiple times. People put their wet cell phones, tablets, or computer hardware in sealed containers and cover it in rice because it absorbs moisture out of them. It really does work very good. Salt also absorbs moisture but that wouldn't be good in this case because you don't want salt inside your graphics card.
