Noisy Fan Issue

If this is the wrong place for this kind of post please direct me to the right place. I have a Super Sonic SC-82P with an occasionally noisy fan. So far the only solution I've had is unscrewing the housing of the projector and screwing it back on. For what ever reason that entirely fixes the issue until the next use when I have to do it all over again. I use this thing for a few hours about once perday at this point 😅 so im basically taking the thing apart and putting it back together everyday lol. I plan on just buying a new fan and soldering it in but figured I'd ask around and see if thats the right move or if there's an underlying issue that im unaware of.
