I was even thinking of one of these crazy yet cheap server power supplies.
I got one here that can make 13.2 volts at 140 amps! Yeah. wow, BUT the
thing is small with two tiny screaming muffin fans, for cooling, even
tho there are two, and they are screaming loud! Yet they don't move crap
for air. Holding an incense stick burning near the air vents and you can
determine what way the air flow is. Barely, if it is moving 1 cfm I'd be
amazed.
Hmmm wonder what it would go in a gallon paint can of transformer oil?
Sure would make it useable. Right now unless you mount it in a different
room forget hearing anything.

There's a good chance submersing in oil would change the values of
some components. 200 fluid of a very low viscosity would work.
OTOH it takes very little water to adequately cool a legal limit amp,
be it a SS or tube type.

has anyone ever thought of just immersing the whole amp in mineral or

REPLY:
it could be done but you still have to get rid of the heat. Keep in
mind that so-called "water cooled" amps are really cooled by air. The
water is just a medium to carry the heat from the tube or transistor
to the heat exchanger.
The exception of course, is if you have a continuous stream of
incoming cold water which is discharged without recirculating.
