There's some kind of whirring sound coming out of my graphics card and on the outside theres no cable touching it, and inside too as far as I've noticed. It's been sounding like this since I deep cleaned it after no use of 5 years. Im thinking of ordering these fans. Some people say the screws dont fit. So im ordering these after asking google ai. Will this be okay?

What is the exact thickness of the thermal pads on the graphics card?
