I've had very good luck shutting up XT2190's
and RD54's simply by
turning
them upside-down. In my particular set up (old pee cee
cases) they also
run _much_ cooler. That might present mounting and cabling
complications in your situation. YMMV.
If turning it is a fix then flip the MV2000, they are rather small
anyway.
