that really sucks...although "non conductive" fluid is labeled as such, so is pure H2O.
Dust on the card itself, dust from the air, anything other than the fluid CAN conduct current when the fluid contacts something.
The new fluids give you a decent chance when a leak is actually occuring in front of you, or when you first notice it to turn the system off and clean up.
I really feel for you...I am so paranoid the first time I turn my pump on for a new PC. I don't run the loop outside, I don't use clamps, and I leak test with all the hardware in and power off: if I had a leak, with no juice on, I am reasonably certain I can clean up the PCIce and dry it out for a couple days and be "ok."
I can respect that you are taking responsibility, and not trying to take more from Newegg. That's integrity, and fewer than you know actually have it.
make sure your Motherboard can get dried out...good 3-4 days out in good ventilation. Best of luck, be careful.
