Tbh all GTX 400 series cards are noisey, its fermi afterall. Some people can withstand noise better than others so to someone else the fan noise might be quiet but to another its unbearable.
I have had 4 in total and the Gigabyte is inaudiable.... The Palit sounded like a Dyson hoover, the EVGA had a horrible Buzzy fan and the Zotac was just Horrid...
