[wellylug] cpu temperature reported incorrectly

[Nigel Roberts]

Hi Simon,

This might be an issue of where the temp is being read from.

I think the Athlon XP series have a sensor on the chip itself, which
is used if the board supports it. Some boards have a sensor directly
under the CPU. Readings from both can be reported as the "CPU temp".

It wouldn't surprise me at all for an on chip sensor to jump straight
to 40C and then to sit at 50C.

Regards,
Nigel
