Could add TO-18 style heat sinks to them!


Might not that make things worse? Is the source of the heat
the capacitor's internal resistance? Or is it ambient?


Welp they heat from both external and internal but increasing the
surface area would theoretically be an advantage would it not?


If you were trying to dissipate internal heat, yes. But if the environment
were the problem, you might be simply increasing the area available to pick
up heat.


Ok then scrap the TO-18 sinks. How about individual Peltier coolers
for each cap?


Don't forget to remove the plastic cover surrounding the cap. That's got
to be good for a few degrees C.
