So, watercooling finally bit me in the ass. I had just finished flushing my system, leak checked all the lines, yadda yadda yadda. So I pour the coolant back into the res, but evidently, some had dribbled back down the pitcher, and a pencil eraser size drop landed on my card. I didn't realize this until it was all over, I feel like a tool. Oh well, no use crying over spilled coolant I guess.
