"My Rx480 card keep on hitting 100% fan speed during idle or when i am just surfing chrome. I have RMAed three times and the problem persists through all 3 cards. I tried using MSI Afterburner Fancurve to force it to follow the curve, but my computer crashes (turn off suddenly) out of nowhere. Upon booting my computer again, i can hear my gpu fan goes full speed before slowing to normal again. Thus, my computer crashed most likely when MSI Afterburner tried to force fan setting simultaneously when my RX480 goes 100% fan speed."
