well observed! I always disliked the idea of ruining my fans with those self-tapping screws, so I came up with that idea:


you need:

  • PEM BSO-M3 or BSOS-M3 inserts, length depending on your fan thickness
  • some nice looking flat head M3 screws of your choice


first, inserts the PEMs - they'll slide in smoothly



second, get the fan in position



third, fix the screws



keeps the fan as good as new and those screws look way better than normal fan screws  :p
