...That if you do have a small leak on your graphics card, that you take the block off and dry the card before reinserting it into the loop. I found out the hard way this morning that water can hide under the RAM ICs and make the blue smoke escape. My 8800GT still works, but only at 800x600, and it's not detected properly. Boo. Anyone else had any stupid mishaps, with watercooling or otherwise?
