Ok, so in a "I am the dumbest man alive" moment:

I just got my second GTX 760 to SLI. I was also getting ready to install some new fans so I pulled most of my components out of my PC to reorganize wires and what not.

Well it seems once I got everything apart it was pretty late so I figured I'd just come back to it the next day. The cats electric water fountain (yes no need to discuss cats or the fact that they have a fountain) is stored in the office where the computer is, so since I had all of the computer parts lying all over the place I figured I'd just take the fountain and put it in the hall.

As I was picking up the awkward device full of water (apparently I think i'm superman and didn't take any precautions) and open the door to put it in the hall, about a cup full of water spills out and low and behold directly onto BOTH of my GTX 760's that were laid out on a box.

One of the 760's was pretty much completely covered and the other just had some residual splash from the main one getting hit. First, I cursed myself for being such an imbecile since I haven't even hooked these graphics cards up yet (just got them in the mail today).

I then blotted up any water I could visibly see with paper towel, after that I got a new can of compressed air and blew off as much of the water on the cards as I could before the pressure ran out of the can / the can began icing over on the outside from over use. I then went and filled 2 boxes with rice and completely submerged the GPU's in them. I am leaving them there all day today and when I get home from work I will use a blow dryer to remove any excess moisture that may not have come off in the rice before plugging them in and testing.

My questions are:

1) I did not have any rubbing alcohol lying around to take a toothbrush to it. I'm hoping between the quick paper towel blotting, condensed air and rice I should be okay? Feedback on this would be appreciated.

2 and most importantly) Do you think the card(s) will be okay? They were unpowered and not connected to anything else, so everything i've read in other places seems to say that they have a much better chance than if it were plugged in.

3) If the cards DO power on, is there any tests or anything i can do to verify they are running properly? I just want to be sure that even if they do power on (which is the main hurdle) that I''m not running the system with damaged goods or am not able to achieve the speeds that I should be able to/graphical potential due to some unknown water damage.

As can be expected, my heart is sinking due to the fact that I had just purchased them that day (yesterday) and hadn't even got them into my PC before being an idiot and spilling water all over them. Any feedback is appreciated!
 
Solution
yes, if you had them powered on you most certainly would have caused irreparable damage.

1) yes there's not much else to try. next steps would be to completely disassemble them, clean out any residue from the water and reattach the cooler. but this can cause more problems than it fixes.

2) depends on whether water got inside them or just on the surface(s). it's it's just surface leaving them to dry is plenty.

3) most of the pcb (printed circuit board) is immune to water damage IF it has dried out completely so that it doesn't cause short circuits - the integrated circuits (gpu chip itself, the ram modules) are water proof and so is most the pcb. the worse affected in my opinion is the fan if water got inside it - though it would...
Just wanted to update: My fiancee had let a friend borrow our oven thermometer and our ovens temperatures can vary a bit from what we set it at so I didn't want to take a risk of "baking" the cards without being able to monitor what the actual temp was. However, I did use a blow dryer on each card for 5 minutes.

Let me say that the rice bath definitely dried these suckers out, not an ounce of liquid to be seen. On the flip side, they left "rice dust" over everything. I tried using compressed air to blow it off but it was too thick / more of a residue. I took a Q-tip to both cards and got everything visible off, but i'm sure theres still plenty of rice dust on the inside / underside of the cards (as removing and shaking all of the rice out of the cards was a task in itself).

I would like to report though... the cards work! No powered up fine, booted in, no artifacts or anything like that on the screen, they SLI'd just fine as well... so unless something "creeps up" later down the line (cross fingers), I'm good! Thanks everyone for your suggestions and for helping to alleviate my fears! It's a beautiful thing to have two cards working in harmony together, and even more beautiful when they are not swimming in water!
