But they have not provided much support for the their cpus so far and provide much more support for the gpus. Unless AMD miraculously provides the drivers directly for Linux. Took two years for the progress on Zen 3. The same is going to have to happen for Zen 4. The fact that we have sensors available for Zen 3 is because the 3rd party devs finally got their repos upstreamed into the latest hwmon branch of the latest kernels. On linux systems: Install the pyspectator module: pip install pyspectator Put this code into a file cpu-temp. Forget about the others sensors on the motherboard showing things like voltages or fan speeds until the boards can be reverse engineered.Įven now, the old Zen 3 mobos and mainly Asus boards are only getting basic drivers for the sensors and those don't show up unless you are on 5.19 kernels or better. Until the while loop you gets continuously the actual value of the CPUs temperature. Based on what I read on Phoronix, you need at least kernel 6.1 to even get the basic temp directly out of the cpu. You have to have the latest kernel branches to even have drivers like k10temp working. Check CPU temperature in Linux command line You can check the CPU temperature using a command line utility called sensors. Apparently AMD changed everything that worked with Zen 3 so all the devs have to start from scratch. Reverse engineering everything about the Zen 4 cpus and the motherboards. 6 Answers Sorted by: 49 I like hddtemp, which provides a pretty standard way of getting the temperature for supported devices. won't release that data into the clear because they consider it proprietary.Ĭorefreq-cli is probing the hardware directly via SMU calls and basically guessing where the registers are and how the data is represented. Linux OTOH is open source and any documentation is public and the mfrs. Windows can because Windows developers have access to the datasheets for the SIO chips because they sign NDA agreements with the manufacturers. But so far no drivers have been implemented to find the SIO chip registers or addresses they use. Lm-sensors depends on being able to detect the SIO chip on the motherboard.
