Even if the system temperature isnt that of the northbridge chip, if
the temperature sensor is located at a point with bad air flow(out of

internal flow patterns of hot air ).

The point is that, at a certain point, heat will stop passing from the CPU
and harddisks to that point with bad airflow.

In a closed system, nothing can become warmer than the hottest heat source.
You cannot accumulate heat just by not transporting it away, you need a heat
source hotter than the current temperature.

The temperature of that point with bad air flow will never become hotter
than the hottest of the heat sources in the cabinet, which is likely to be
the CPU.

I'm sorry, but what you propose is physically impossible.

You forgot the fans. They blow air and remove the heat from the cpu to
other points in the internal of the case. So things like what i
suggest can happen. Your view of the situation is rather simplistic
i.e two points A and B , A is hotter, B is cooler, and B no matter
cant become hotter than A. If you have a device which with mechanical
work transfer heat, then anything can happened, like transferring heat
from a hot to a hottest. This is physically possible and in accordance
with the 2nd thermodynamic law. Also you tried to view only by
thermoquasistatic-dynamic point of view. You forgot the fluid dynamic
point of view(fans and forced airflow regardless of temperature
difference.)
