centrifugal fans sourcing :

- Reuse the 4 M3 stock UM fan duct screws
- The centrigugal fans don't need to be screwed, just to be clipped,
- Reuse the stock UM fans plugs by welding the wires to the new fans, what I done. ( when cutting wires keep 20mm wires on the stock fans, they can still be useful)
- Or source & add new " Cables 120mm long, plug JST XHP-2 "
Anyway, careful to respect the polarities
- the fan duct can be tilted by rotating on its hinges for an easy access to the Olsson block
- recommanded use aluminium tape sticked inside the central portion around the nozzle hole
