how do you remove the fan? im struggling so much to get the last screw out (furthest away) as i cant even see it!!

how is this even possible to do while led upside down, no view of the screw and no room to fit, let alone twist a ratchet?

it there another tool i should be using?

managed it, but what a pain! had to rip out that thick blanket on the bulkhead to gain access/room for my small ratchet!
