full-on would be annoying as well. Think a DC fan (of similar
dimensions and air flow rate) would work? Implemntation would be
simple: 115VAC-12V transformer, bridge rectifier, filter cap.... That
would preserve the dual-speed feature without getting into the temp
sensing end of it. There's plenty of room inside the case.

Delta Electronics makes a series of DC brushless fans
called Sensflow with builtin thermal sensing control.

I have one that's 12vdc, 4.75" square.
There should be a size, voltage, and flow-rate model to fit
your needs. You might find one that can be used with the
voltages available inside the amp without needing an additional
ps to supply the fan, or the amp may have 12vdc already.
