Yeah, so I unscrew the arms from the fans, versus the blades from the arms, and because I don’t wanna mess with the rubber gromets or whatever those pieces are called. They seem to be slightly dessicated where they’re exposed, and I feel like if I were to remove the screws from there it’d be all over. The arm to fan body is just metal screw into a machined hole, and who knows, maybe I’m tightening up a joint that loosened since I last cleaned the blades (which is definitely not a short amount of time, I don’t exactly do it a lot).
