#Linux Mint | I'm not able to see core by core CPU temperature or fan speed, is this expected?

Hey all -- I recently built this gaming PC (hardware info below) and I'm not able to see as much detailed CPU core temperature and fan speed as I thought I would.

Some basic hardware info:
MSI Motherboard: PRO B650-S WIFI (MS-7E26)
CPU: Ryzen 7600x
GPU: Radeon 7900 GRE

What I can see is what I have attached as a screenshot from CoolerControl. Some of the stuff that I can see for my Ryzen CPU is:

  • CPU Temp Tctl
  • CPU Temp Tccd1
    *but no fan speed

What I can see for my GPU is:

  • GPU Temp Edge
  • GPU Temp Mem
  • one fan which is at 0 rpm

Is this expected for a system like this?

I attached some system info for much more detailed hardware info if that helps too!

try psensor from the repos

psensor also gives pretty much the same info:

#

perhaps missing coretemp thing. not sure if it's its own package, or a subset of lm-sensors

#

test the command watch -n 1 sensors

#

Sensors:
System Temperatures: cpu: 40.8 C mobo: 32.0 C
Fan Speeds (rpm): N/A
GPU: device: amdgpu temp: 32.0 C mem: 50.0 C fan: 0 watts: 12.00
device: amdgpu temp: 36.0 C

#

fans may not have rpm sensor or it's for bios display only

this is what I see instead:

#

thank you for the help btw

#

this doesn't seem like it should be expected right

#

the temps look fine you're just missing the cpu core values.

midnight ocean
#

yeah, apparently I can only see an aggregate metric

#

that's what CPU temp tccd1 represents

@midnight ocean run sensors -u and check output

hey @golden slate same info as running sensors basically:

You have an AMD Zen processor

#

So it has a CCD temperature sensor and that’s actually it

#

Your chip doesn’t report all the core temps like Intel does, it reports the CCD temp and that’s all it can

midnight ocean
#

sounds good, I was basically looking for confirmation that what I was seeing was expected

#

what about the CPU fans though? I'm guessing it doesn't have a sensor either?

#

I can only really see the fan for the amd gpu I think

golden slate
#

They are generally pretty standard so they should

midnight ocean
#

I think I have the option to select PWM in the bios, let me try that and see what linux mint picks up, thank you @golden slate

@golden slate Wondering if this might be the issue, the I/O chip on my mobo is this:
