Great point. You'd wonder if the heat threshold was lowered, or if the cpu
is performing more instructions generating more heat.

Correct. But in the case of thermistors, they are designed to be run
within a temperature range. Their accuracy isn't likely to drift with
use. If it were to provide false readings, it would most likely be
caused by the thermistor failing closed or open.

I don't believe the thermistor has failed because it does successfully
provide readings when using Gauge Pro in OS 9.
