I recently acquired a Radeon HD 6790 and the fan on it is really loud. I've used MSI Afterburner to set up custom fan curves too see if that would help any, i have also let my drivers manage the fan speed and nothing seems to help. I've used MSI Afterburner to set the fan speed to 0% and it still sounds like the fan is running 60%+ speed. The only time i have ever got the fan to be completely quite is set MSI Afterburner to 100% fan speed and leave it there for about 3-4 minutes and then drop it back to 0% really fast. The fan will be completely quite for about 1-2 minutes then sounds like it zooms back to 60% and stays loud again. I've taken the video card completely apart, sprayed out the heatsink and the fan, and replaced the thermal paste. I looked around the fan to see if there was a way to lubricate the bearings but the fan is solid on both sides except for the power connector coming out of the back. Is there anyway to even lubricate these bearings? Is there anything else i can try that i haven't said yet? I really don't have the money to buy a replacement fan at the moment so i'm willing to try anything else at the moment. Is there a BIOS setting that could make the fan go crazy like this? Any help and/or suggestions are appreciated, Thanks
