Speedfan Temperatures?

What are the third temperature and the ACPI temperature that Speedfan reports?

I have an Asus A8N-E mobo with an Athlon 64 X2 4400+ processor.

T1 is the CPU temperature.
T2 is the mobo temperature.
HD0 (via SMART) is the HD temperature.

But what are:

ACPI temperature, which always reads 40C?
T3 temperature, which varies rapidly between 28C. and 45C. depending on CPU activity?

Any ideas anyone?

Thanks for your reply.

Another query:

What is the difference between MOBO temperature and CHIPSET
temperature? Are they different names for the same temperature?

I may have solved the T3 mystery. It is related to CPU activity.

Ctrl+Alt+Delete = Task Manager > Performance. CPU usage is displayed.

Speedfan > Charts > tick T3. T3 value is displayed.

Load CPU to 30%. Wait a bit.
Load CPU to 50%. Wait a bit.
Load CPU to 100%. Wait a bit.

Compare the CPU usage and T3 value displays.

Correlation is almost exact.

Comments welcome.
