G3 and G4 processors have an on-chip temperature sensor called the

'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die

temperature within 2-4 degrees Celsius. This option shows the current

on-die temperature in /proc/cpuinfo if the cpu supports it.

Unfortunately, on some chip revisions, this sensor is very inaccurate
|
||
|
|
and in many cases, does not work at all, so don't assume the cpu

temp is actually what /proc/cpuinfo says it is.

either changing a lot, or the TAU hardware is broken (likely on some

G4's). If the range is small (around 4 degrees), the temperature is

relatively stable. If you say Y here, a single temperature value,
