I also removed the aluminum top of the power supply as I figured out

the vent mounting is at the front and does not give good air circulation

Yes, the whole IIGS is not designed to cool well. It's easy to blow
air around inside, but what you really need to do is draw cool air in
and exhaust the warm air. I ended up using a fan mounted to the
powersupply and a strip of foam between the powersupply and the lid
so that the hot air from the P/S is forced to exit out the top. Since
the vents in the lid are so small the natural tendency is for the fan
to simply move the air in a nearly closed loop, getting hotter with
each cycle. Over time, this dries out the electrolytic capacitors,
and your P/S fails.
