MPT-7210A Loud Fan Fix - How to quiet the fan on this Boost Solar Charge Controller

I present several quick and cheap ways to fix the fan annoying high pitched fan sound on the MPT-7210A Boost MPPT (well it's not really MPPT) Solar Charge Controller. The method I chose does not require 3D printing, cutting or grinding. There are more elegant ways but this will do for now. Thanks for watching, DDSolar

Update 9/2022 I've had this fan mod on my MPT 7210A charge controller for a few months and it's working great. I can barely hear anything.
