Hello! I have this video card Sapphire r9 280x 3gb Dual X and I noticed that the fans are not spinning, When I bought the card only 1 fan was spinning and the other one was idle and came back online when it was needed but after some time i saw that the first fan (the one who was always spinning) is not spinning anymore and I'm scared cause when the fans spin the card is like 80 degrees and both of them are spinning at 100% then when the card gets to 50 degrees both turn off. When the fans turn on i can hear a slight sound of electric spark or something like that. What can I do to keep at least 1 fan always on?
