[RE-wrenches] GVFX3524 fan replacement

[Kent Osterberg]

For a GVFX you don't have to worry about reinstalling the large o-ring 
on the perimeter of the case, so you can do it without taking it off the 
wall. Don't think I'd disassemble a sealed case unit without taking it 
off the wall because it is just about impossible to get the o-ring back 
in place. But you have everything removed to the point that there are 
only four screws left, so you might not be saving any time. To protect 
the ribbon cable during reassembly I put a heavy piece of paper (like a 
slick coated business card) over it that extends to the outside. When 
the case screws are partially tightened, the paper is removed.
