Temperature sensors not detected on AMD Ryzen 7 7800X3D

gr flag

I’ve recently installed Ubuntu 22.04.2 LTS on a PC with an AMD Ryzen 7 7800X3D and a ROG Strix B650E-E Gaming WiFi motherboard. I was trying to monitor the CPU temperature using lm-sensors, which does however not show any values related to the CPU:

nvme-pci-0900
Adapter: PCI adapter
Composite:    +40.9°C  (low  = -273.1°C, high = +81.8°C)
                       (crit = +84.8°C)
Sensor 1:     +40.9°C  (low  = -273.1°C, high = +65261.8°C)
Sensor 2:     +40.9°C  (low  = -273.1°C, high = +65261.8°C)

amdgpu-pci-0c00
Adapter: PCI adapter
vddgfx:      1000.00 mV 
vddnb:         1.02 V  
edge:         +38.0°C  
PPT:          23.19 W

I tried running sensors-detect, which was unable to detect additional sensors

In /sys/class/thermal/ there are also no thermal zones showing up.

My BIOS is able to display the temperature, so the sensors should be physically functional.

Am i missing any drivers here that need to be installed manually?

@obezyan After an OS update to Ubuntu 23.04 the sensors are now surprisingly detected by k10temp. Thanks for the response anyways.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
