I have two problems with my R9 290x. So three months in to using it a coil whine started (a buzzing noise when gaming) after a thunderstorm. I eventually RMA'd it and when I got it back it still had a coil whine. I asked the guys at XFX and they said that it may be my power supply because of low wattage so I upgraded it and it still persisted so I am thinking it may be that my motherboard is damaged. Second I have a high heat problem with my GPU, it gets up to 90+ when watching you tube but my fans don't change speeds. I am forced to use MSI Afterburner but I am not sure why this is happening. Does anyone know a solution to this? Has this ever happened to you guys?
