Need to replace fan in the GPU

I'm trying to remove the fan in my 280 but I can't get the big metal heatsink out because of small screws which every screwdriver I have isn't compatible, What screwdriver do I use?

Hi @stolas,

Post some clear, close up images of the screw heads.

Maybe someone can identify the type/size of driver needed
