I buy this fan to replace my gtx560tus , since the 560 be make loud fan noise due to bad fan bearing problem , I return it and get this card for 289 , and it be a used card , I be surprised that amazon do not test this card out fully , I be aware that this be a return unit and there must be some problem previously , but it be a lot cheaper than the new one , and i be stupid enough to kind of get into the double fan crap . this card at stock clock , do about 5 to 10 frame better than evga gtx560ti fpb at 850 in trine 2 at max setting and 4x aa , temperature go over 80c when fan be set to auto and over 60 % speed , it be rain here today in LA and ambient temp be about 55f , i will say it run pretty hot , it have good performance but , the fan make rattle noise after 50 % of fan speed , but it be quiet at 40 % which be auto speed . I think amazon do not test the fan speed , , , but whatever , I buy the asus version of gtx570 , and the new one be 299 . it be still on it be way , but i be sure it will do better than this card .
