i have had exactly the same problems....broke 2 GTX280 cards and finally go to air, which works fine till now!
I tried with EK Block rev1, with EK block rev 2 (Eddy send me copper replace) and two GTX280 which worked fine with air. Finnaly broke the two of them (system didn't boot) and now i am working with the third one. The first was Evga, the second and the third was Asus GTX280. Keep in mind that it is my 4th watercooled vga (6800-7800-8800-GTX280) and i broke 2 of 3 GTX280!! Also note that my DD tieton block (yes i had also a DD block for this card) didn't work with asus! (large gap between core and block). Anybody else had trying watercoold an asus gtx280 ?
