The fan on my XFX HD667X started failing recently; XFX sent me a replacement fan that I'm trying to install. This is my first time replacing a cooler of any type. The new cooler came with 2 small spongy rubber spacers (?) attached to the card side of the cooler. The old cooler didn't have anything equivalent on it. Are these just shipping material that should be removed before installation? Or are they to protect underlying components from contact with the cooler? Will the cooler still make solid thermal contact with the GPU with these pads in place? Has anyone seen anything like this?
