How many are "some" ? - I would like "Original" S5's not modded ones.
I do not have any of S5 with original S5 fan.
All they have 2 x S3 fan, which is a little quieter.
If S3 housing is for You "modded", it is also difficult to help. S3 bottom were screwed with four screws and it can be put on each S5 miners.
The S3 sides and the top part is made of a single U-shaped piece of metal sheet.
If you find that S5 plastic sides are better ...
Obviously, I have a few S5 original plastik sides , and I can unscrewed the bottom.
But I do not have left any fans from S5.
These miners I can offer a total of 5 pc
