"don't trust [cabinet's] ventilation system"

(a short true story)
the house was cold, we were told
inside a box a motor ran not too hot
inside this same box a bigger motor ran too hot
inside this same box a smaller motor ran too cold
a call to Bare Your Problems Inc. was made
3 hours later
Hark! the doorbell rang 3 times
Churak opened the door in a flash
the door beared 3 bare young sweet ladies
one had hair so fair
one had hair down to there
one had golden locks to make all men care
now Churak ran too hot, as he stood there
like that stick finding water and pointing downward,
Churak started to point upward with a count of 3
- intermission - (curtain falls)
(later) curtain raises
for the box with motor that ran not too hot
the hair so fair said it was cool, just right
for the box with smaller motor that ran too cold
the hair down to there removed the ventilation fan
and the motor ran cool, just right
for the box with big motor that ran too hot
golden locks took fan that hair down to there removed
and place the fan into box too hot
and then and then
the box too hot got extra too hot, aka very too hot
Hark! the doorbell rang
entered: Sir (not golden lock) Homes
and Dr. Want Some
Turns out that extra fan only fitted inside the box too hot
in only one area, and by chance it directed its air flow
directly onto the thermostat, cause a false and lower
read of the box's internal temperature. The control panel
determined the ideal running temperature was too cold
so it cut power to the original fan. With the second fan
hooked up in series with the first fan, both stopped.
The thermostat quickly became hot and started up the fan,
but also started was the added fan that quickly cooled down
the thermostat by blowing outside air onto it rather than allow
the air heated from the motor to circulate onto it.
aka,
- more help was less helpful
and,
"The doors on the cabinet are wide open because
we've got so many high-BTU machines in there
and I just don't trust the cabinet's own ventilation system."
imagine,
By opening the cabinet doors, the engineered air flow
inside the cabinet was violated or interrupted etc
causing a designed air flow to be redirected,
and eventhought the fans never turned off,
they were not as effective as when cabinet doors were closed,
as that was the model the engineers assumed during operation.
so,
or but,
Some places I know of did that open the doors,
but they also placed a high velocity external fan
directly pointed into the opened cabinet door,
and a few actually have like a long sewer plastic
hose about 2 feet in diameter snaked out of the room
into a cooler or cold room to have that air be sucked in
by the external fan that then blows it into the cabinet.
also,
Electronic circuits overheating can be like code running
in memory where bits are corrupted, causing abrupt conditions
that can not be handled as errors since the error handler
did not include the delivered situation report as a possible,
so the error handler "Panics" and does a "full stop" and if
this happens before an overheated error is reported,
then the too hotted heat will not be logged as the cause.
guess,
This could be just a slow overheating that doesn't reach
the hight temperature to report a problem, but running
the machine at just under a "too hot" situation over time
causing eventually a critical bit to flip flop or circuit to oops.
if so,
Then a cooling off period would cool off the circuit,
or the reloading into memory load unerrored bits.
