CPU temperature reading stuck #49

Closed pshemk closed 4 years ago

pshemk commented 4 years ago

I'm not sure if this is possible, but my CPU temperature reading (and only that single reading) is somehow stuck at 70°C: image

I've tried rmmod and modprobe again but the reading doesn't change. I also checked the zenpower module and that one keeps reporting the temperature changes as expected. This is on Asus X-470 Prime motherboard with AMD 3900x CPU.

Are you using a version of the driver after this commit (Sept 2019)? https://github.com/electrified/asus-wmi-sensors/commit/8f5eaec0b29800f78999d8817d0c8fde14e978cd

PS is that Grafana? Nice work!

I'm using the current git version. After a reload the machine started to report correctly again.

And yes, that graph is from grafana :-)

I think it's most likely that the problem is in the Asus firmware unfortunately :(.

Similar issues have been seen by other users, and also in Windows (see my comment here: https://github.com/electrified/asus-wmi-sensors/issues/48#issuecomment-578498632)

The WMI issues also seem more frequent on 3xxx gen CPUs.

You've inspired me to set up prometheus/node_exporter/grafana, I will monitor my own system more closely to see if I experience this issue.
