Indeed. I *strongly* suggest you add additional bottom fans to get
the output down to the 30C area.
Heat is a very insidious enemy of electronics. If you are lucky,
it makes something croak hard. But usually, it causes various
intermittents and subtle degradations. The old pressurized-floors
were a Royal PITA in many ways. But they also kept big old ugly
boxi [Can you say VAX 785 + RA81's] cool enough to last and last.
