My 260x has started to make noise recently(guess the noise is from the bearing)...only when the fan is at 40 to 50% speed and when starting th pc up ...have a custom fan profile with afterburner...i've been having a lot of issues with the gpu like black screen crashes when the pc is idle..is there a way to fix the fan noise and what could be the reason?...just wondering if the fan has gone bad because of the custom profie i have with afterburner...
