What would be this temperature indicator?

English Hardware
#1

When I run sensors on my laptop I get this:



Minas-Anor:~ # sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:        +40.0°C

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +34.0°C  (high = +105.0°C, crit = +105.0°C)
Core 1:       +34.0°C  (high = +105.0°C, crit = +105.0°C)

Minas-Anor:~ #

What thing would be the first temperature indicator? Motherboard, disk?

smartctl says the disk is running at 46ºC, it doesn’t match.

The video is motherboard integrated intel (“Intel Mobile 4 Series
Chipset Integrated Graphics Controller”), I guess it is not that one.

Airflow?

No one?

The overall system temperature, wherever the sensor is positioned on the mobo. It’s not just measuring a single component. I’ve never bothered to locate it exactly on my lenovo notebook. I did do that on my desktop PC which had an Asus mobo, and the sensors’ chip data was in the mobo’s manual.

Your temp levels are similar to mine. IIRC above 40C the fan kicks in on mine and it appears in sensors report with a value for rpm.

Well I decided to take a look at: Mobile Intel GM45 Chipset - Technical documents where you can go for the Chipset Datasheet, and read through section 11
Thermal Management.

Enjoy. :slight_smile:

See this Device Support Status page at lm-sensors.org. Scroll down to entry under manufacturer “Intel” for chip “82965GM/GME, GM45, Q35, G33, Q33, Q45, G45, G41, B4”. Explore the additional links under Status/comments (rhs column).

BTW, running “acpi -t” also gives a temp of around 40C here, but calls it Thermal 0. I no longer get the 2 x core temps with that acpi command.

Thanks. I’ll look all that when I get a better internet connection next
week, now I’m limited to 500MB/month.

Oh, and here is my sensors report (run as normal user):

acpitz-virtual-0
Adapter: Virtual device
temp1:        +41.0°C  (crit = +105.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +36.0°C  (high = +105.0°C, crit = +105.0°C)
Core 1:       +36.0°C  (high = +105.0°C, crit = +105.0°C)

thinkpad-isa-0000
Adapter: ISA adapter
fan1:           0 RPM
temp1:         +0.0°C  
temp2:        +41.0°C  
temp3:         +0.0°C  
temp4:         +0.0°C  
temp5:         +0.0°C  
temp6:         +0.0°C  
temp7:         +0.0°C  
temp8:         +0.0°C

When/if GM45 chipset is properly supported by lm-sensors.org, those “temp1” etc. names should change to something more relevant, and those not applying should be gone.

Note that acpitz-virtual-0 and thinkpad-isa-0000 are reporting differently, temp1 versus temp2 always the same reading, probably sourced from the same sensor. With proper support, that should get tidied up.
