Case temperature

ASrock 4CoreDual VSTA with e6400.

Speedfan reports:

temp1 28C
temp2 38C
HD0 42C
HD1 38C
Core 0: 47C

What are temp1 and temp2 please? The help says they are case temperatures,
so does the motherboard have a case temperature sensor and why the 2
figures, 10 degrees apart?

Wait a minute - perhaps the temp2 (38C) is the temperature of the CPU -
between the cores? Question still stands - is there a case temp sensor on my
motherboard (temp1)?

No way to know, that's why you need to use a motherboard
specific software or the bios to compare with.

You could do some experiments to figure it out, like taking
some masking tape and wrapping it around the chipset
heatsink, or unplugging any fans and watching which temp
rises. Also you can visually search the board for any
discrete temp sensors.

The help says they are case temperatures,

Which means nothing, because any 3rd party program needs
programmed for the specifics of the board. It might be
"case" temp or might not. The others might be case temp and
any or all temps might be wrong - they might need some
numerical offset applied to be valid. However, if we were
to assume all is read and interpreted the best it possibly
could be, I'd assume temp1 were case ambient nearer the
front intake, and temp2 was a chipset temp.

so does the motherboard have a case temperature sensor and why the 2
figures, 10 degrees apart?

You tell us, does it? Look around on it for a discrete
sensor. It's typically a bi-pin "blob" about 2mm wide and
kinda pointed on top, typically either solid green or blue
with a white tip. Since (normally) no other motherboard
components look like this, it's fairly easy to find (unlike
video card sensors which require a lot closer look).

Looking in the manual will give you a hint.

The hardware monitor screen in the BIOS, has four voltages, two fan speeds,
and two listed temperatures. The listed temperatures could be analog ones.
They are labeled as CPU and Motherboard in the BIOS screen.

Speedfan could be accessing the digital temperature from the processor
(PECI, Platform Environmental Control Interface). And the BIOS hardware monitor
screen, might not be prepared to display the digital temperature information.

To tell the difference between a thermistor (external) temperature reading,
versus diode (internal) or digital temperature (internal), fire up a program
like Orthos, and if the readings shoot up instantly, the sensor must be
internal. A sensor which changes gradually, could be a distance away from
whatever is getting hot.

What are temp1 and temp2 please? The help says they are case
temperatures, so does the motherboard have a case temperature sensor
and why the 2 figures, 10 degrees apart?

I'd say that they are mobo-mounted thermisters. temp2 is probably in/very
near the CPU socket and the other is typically towards the rear of the board
near the graphics slot.

I had such a facility with my last board, but this one doesn't come with any
monitoring software!

Much clearer readings - it labels the readings. In my original post, temp1
becomes motherboard. temp2 is CPU, but Everest doesn't give the 2 Core
readings.

Is it the Core temperatures, or the 'cpu' temperature that I should watch
out for? I believe a sensible limit for the e6400 is 50DegC and mine seems
to peak around the low 50s on the Core0&1 readings, but temp2 is a few
degrees lower, peaking in mid 40s, which suggests I could overclock a little
without much trouble, but which temperature does the 50 limit apply to?

OK, installed it and got odd results - I have Core 2 Duo E6400 (2133MHz).
Everest says my CPU FSB is 128MHz and CPU speed is 2048MHz. Guess I need to
boot into my BIOS and see what is going on as I haven't changed any values
in there for over/underclocking !!

Right click on my computer confirms the low CPU reading!

How about bios?

Do not guess or assume any 3rd party utility is labeling
anything correctly. Nothing suggests anything because all
these numbers are within the realm of possiblity for any of
the parts. The CPU can actually be cooler than the
northbridge when mostly HALT-idling, for example.

There's a real easy way to resolve, run a CPU stress test
and watch which number immedately climbs.

indeed.

I've had speedfan not label them.

But 2 different pieces of third party software labelled them
differently

good idea
