A little off topic but It seems many instruments (the SR620 and 53132A included) would work best with an internal fan. (A closed system, not exchanging outside air). Possibly with some sort of internal/external heat sink if needed. Or in high power situations outside air would flow through a hollow heatsink (again not exchanging outside and internal air). If nothing else this would keep dust out. Since fan filters can really restrict air-flow and without a filter dust on circuit boards can act as on thermal insulator leading to overheating while conducting static.
Good point. A fan in a closed environment will survive longer, or rather, won't degrade as fast as it possibly would do.
These days I would assume that heat-pipes would be used to move heat to a large external heat-sink. It's fairly cheap these days.
