I have now have to send back two of these card . the first have a fan issue - a grinding\/crunching noise on the rear fan at 45-65 % speed . this could easily have be find in the factory with a simple fan test , so it imply very low quality control . the second I buy from a different retailer -lrb- hope they have better stock -rrb- , but no luck . the card be unstable -lrb- hard crash the computer -rrb- , would not overclock at all , and come with a stock voltage of 1.21 V. worse , the plastic protector on the shroud be hold together by bit of tape - it look like this card be return by someone , and then resell as ` new ' .
