My fans came with the rubber-like 'isolators' to put in instead of screws. I know how they're supposed to go in, I can get it through the case, but I can't get it through the fan. I use pliers and pull, but the bit won't go through the fan's hole no matter how far I stretch and which direction. In fact I tried pulling it without the fan to see how thin the bit that has to go through gets, and it doesn't seem to get thinner at all, not enough to fit in the fan's hole. It would probably be easy if I could pull straight, but of course the fan has a second side and hole in the way for installing it the other way round. Edit: This is ridiculous. The screws don't go in either. From intense Googling it appears I'm suipposed to just put pressure on them as I screw so it creates its own 'thread', but how do you guarantee it won't go in at an angle and mess up? Mine is always going in at an angle. Also, any pressure and the plastic fan will crack, moreso than it has already due to the pressure of trying to get the rubber mounts through! Edit2: Well I went for it and tried screwing one through as hard as possible, at a slight angle of course. It won't go all the way through and just jams. The amount of strength required just to get to that point feels like this is wrong. The amount of strength require to unscrew it back out makes me know this is wrong. That it didn't make a blind bit of difference to the lack of ease of screwing it back in, as in it won't screw back in at all without the same pressure and strength, is no surprise. Edit3: Right, I'm using a drill. No one told me fans were the most difficult part of computer building.
