I was unlucky and got a card with a faulty cooler, but this is why warranties exists.
I red some same reports at newegg, though it's perhaps 1 customer over 1000
Btw I noticed year after year that even with big names brands you have great chances to get a defect, mass Chinese production without proper quality control...
