I swopped out the original [made in Taiwan] fans in my ARC 120 & 150 amps for Pabst Motoren,Germany, type 4840n fans.
These are small fans and very quiet. In fact I was pleased to see that ARC have started installing them in my new Reference 210 Mono amps., and this also means you should be able to find them in the USA.
Of course you will have to fab some brackets or grilles to mount them and consider air flow direction, etc.
