I'm unable to post pictures, unfortunately, but hopefully somebody can help me. I'm trying to install a Cooler Master MF200R fan in the top fan slot of a Cooler Master H500 case. Included within the MF200R's box was one small bag of tiny screws and one small bag of longer screws. The screw holes align perfectly with the case holes, so there's no issue with that, but it feels like I'm missing a part. The tiny screws require a great amount of force to screw in, to the point where it feels unsafe and as if I'm going to disfigure the screw hole. As for the longer screws... they simply don't do anything. They can be inserted into the screw holes with no issue, but attempting to screw them in does nothing as they are not screwing /tightening into anything. I realize offering assistance without any pictures will be difficult, but is there any form of advice that can be offered to me here?
