Seems to me that you need to know for sure whether or not those bolts 
are bottoming out. Why don't you try putting one in without the flat 
washer and see how loose it is. That should tell you what is happening 
with the flat washer in place.

I've never used RTV as a threadlocker. Does it work for that purpose? 
You need to get yourself some Loctite blue (242)  for future use.

Yes, it will be OK if the bolts are pulling up tight. Maybe with the 
fan being of thinner metal, the washers might even be a good idea.
