[lm-sensors] k10temp

[lm-sensors] k10temp

[dirk.p]

Hello,



This is not dramatic, but I think the temperature returned by k10temp can not be
correct. The temperature is lower than the room temperature of 14°C and lower
than the more realistic values reported by it8728.

Was also looking why I got no information from the Radion card. sensors-detect
tells me

Using driver `i2c-piix4' for device 0000:00:14.0: ATI Technologies Inc
SB600/SB700/SB800 SMBus

but does not add that module in /etc/conf.d/lm_sensors
Every time I load module i2c-piix4 I get something like

[ 2952.162696] ACPI Warning: 0x0000000000000b00-0x0000000000000b07 SystemIO
conflicts with Region \SOR1 1 (20120913/utaddress-251)
[ 2952.162708] ACPI: If an ACPI driver is available for this device, you should
use it instead of the native driver
in dmesg.

The wrong module or something not implemented by the OEM?



Thanks,


Dirk.

Re: [lm-sensors] k10temp

No. It's not always a crappy sensor.

The temperature reported is not absolute temperature. It's a control
temperature normalized to 70 degrees meaning max temp.

And the accuracy is such that its most accurate near "70" degrees and
may be less accurate further away. But given the intended use of this
sensor (to monitor and keep the "temperature" below "70" degrees) that
in-accuracy away from that target is not an issue.

It should be used to verify your cooling solution is working as
intended. It is much more accurate for this purpose than the
motherboard sensors which may not be on the CPU die and are not
calibrated by the CPU manufacturer to help you. If you want to
minimize fan speeds, you can dial them down as long as the k10
"temperature" is below 70

The datasheets are very clear on this.

Phil P.
