Just bought 1 of these this week haven't had it long enough to fully test it yet but so far very happy. I am impressed with the cooler and fans and it seems to be handling the heat from mining well so far. Only issue i seem to get is if i push the card too far my computer just instantly turns off, generally my other cards just stop working for a bit and recover.
