For those folks who have done the fan upgrade, how did you attach your fan to the case lid and what works best? I'm aware of:

Farnell rivets (This was my first choice but unfortunately they won't fit the mouser fan)
Super glue (Is there potential acetic acid fumes?)
Double stick tape (How long will it stick?)
Silicone gasket adhesive (Produces acetic acid fumes)

Anything else that can be used?
