I need advice on replacing the cooling fan on my GAS Ampzilla.
The current fan was too loud, so I tried slowing it down with an
inline resistor. I got the voltage so low that the fan will not
even spin unless I reach inside and give the blade a spin. That
is both easy to forget and annoying to do.

Can I replace this with a computer cooling fan? What size do I
need? How about a speed control? My Ampzilla needs very little
cooling, but if the fan is all the way off it will overheat after
a few hours.

Advice please.

Thanks,
Phil
