Speedfan Temperatures?

Abruzzo · 8 May 2006 at 18:33

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?

i have no idea about the acpi temp. the t3 which varies underload may well be the northbridge on your mobo. you can of course configure speedfan not to show any temps you don't need/are bogus.

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.

Some speedfan values will be 'bogus' - most likely from disconnected or unused thermal diodes.
