I just recently acquired some Radeon HD 5870s that need to put reassembled. I've went all around town trying to find the correct screws but no one has them. I don't even know exactly what size screw it is, but it is the smaller of the two screws used to secure the shroud to the backplate and the shroud to the heatsink assembly on the 5870. I believe it is the same screw that is used to secure the fans to the heatsink assembly. I don't have pictures right now, but I can take some in a few hours. I've went to every hardware store around town: Home depot, Ace, Fastenal, Electronic stores, and no one has it. I tried to message AMD directly about the issue, hoping to get a name/size/spec on the screw, so that I could order them online or call around town to try to find them, but they responded with, "We're sorry that is proprietary information."
I'm currently at a loss as to what to do, has anyone else experienced this problem or something similar?
