Divorce is popular in this country for noise reduction :)

Any recommendations?

There are two obvious alternatives, change the electronics board to some fan-less design or change the fan. Changing the fan seems to be the more economic alternative. I would try a Sunon blower fan and if there isn't one in exactly the right dimension a printed adapter should be fairly simple to design. (Might be worth it just to get rid of that awful origami fan duct.)

Getting a 2.1.x motherboard (UM2/UMO+) is an alternative, but that is pretty expensive and you probably need to upgrade to a pt100 temp sensor in that case.
