This is inside an air-conditioned residence. The room temperature ought
to stay within a range of plus/minus three degrees F.

It's a B2. But I believe the heat spreader is screwed into place.

On mine it rises 13 degrees C and is marked FAIL.
I could not find the VIA spec sheet with temperature limits - but many
modern chips have a limit of 80 degrees C or higher. The application
with the highest processing requirements that I run is Timidity (it
requires interpolation and massaging of digital audio data -- resulting
in a continuous XO-1.5 processor workload of at least 40% of the cpu).
With Timidity running, 'sensors' tells me the temperature gets to 71 C.
[The XO-1.5 back does not get warmer than some XO-1 backs.]
