temperature infos from A7N8X and Duron

[=?iso-8859-1?B?SvxyZ2VuIEhlcno=?=]

Hello there,

since yesterday I'm running that board and was happy now being able to
read the internal temp diode in order to get exact values.

But I'm quite confused since I get values of 18°C from MBM, Asus Probe
and BIOS for the CPU diode while socket is around 40°C. All values
idle.
Under load CPU diode increases to 31°C nearly immediately and socket
slowly to 52°C.

Does anyone here know of such low values?
The Diode is read through the W83l785TS-S chip. That one is also
responsible for alerting if temperature goes over 85°C. But I suspect
it never will - at least not before the CPU gives smoke signals.

Bye,
Jürgen

The Diode is only responsible for reporting the temp, it's up to the
mobo or monitoring software to react to it. The A7N8X has Asus COP, it
will shutdown the board before the CPU overheats.

Durons 600 to 1300 MHz are rated @ 90C max die temp. The socket temp is
usually around 10C lower then the CPU die temp at full loads, the socket
warms up slow, diode temps are instant.

SpeedFan is a good monitor for the A7N8X, CPU fan control is better
then Q-Fan and it has the S2K bus disconnect built in to lower CPU
temps/power usage at idle/low load levels.

Hi,

The Diode is only responsible for reporting the temp, it's up to the
mobo or monitoring software to react to it. The A7N8X has Asus COP,
it will shutdown the board before the CPU overheats.

But at which temperature? On the A7N8X the W83l785TS-S implements COP
and is programmed for 85°C. But if the temperature this chip notices
is only about 30°C on load, I guess it's about 25°C to low. So in
turn it will reach real 85°C or even 90°C long before the chip
notices that -> COP will fail.

And I'm quite sure the 30°C is the real temp the chip sees since I
directly read its registers using i2cdump on Linux.

In any case, it would be interesting for me it's a strange unique thing
I'm seeing here or if such low temps are normal e.g. for Durons on rev
1.xx boards or so.

Bye,
Jürgen
