z650 Predator projector-part number 23.JKYJ3.001 60*13*83 28mm-fans- 2 fan kit not working

Hugo78

have a z650 predator projector hardly used but 2 fan kit not working, acer repair company charged 70 quid to tell me what I already knew but no alternatives offered or ideas to a repair of what seems quite a simple thing. I'm quite technical and before I remove fans would like to know if anyone else had same problem and if they found alternatives as fan kit is discontinued and I now have a grand worth of projector hardly used that doesn't work and apparently cannot be fixed because of such a common part in technology.

please help me find alternative or options out there!

found parts exist on ali express but fans are 2 mm thicker. nothing a file couldn't cut back to fit into cage. beware if doing this repair cables may also be connected in different order to 6 pin connector
