Hi, Here is the output for sensors-detect: # sensors-detect version 3.6.0+git # System: ASRock B650E Taichi [Default string] # Kernel: 6.3.1-arch1-1 x86_64 # Processor: AMD Ryzen 9 7900X 12-Core Processor (25/97/2) This program will help you determine which kernel modules you need to load to use lm_sensors most effectively. It is generally safe and recommended to accept the default answers to all questions, unless you know what you're doing. Some south bridges, CPUs or memory controllers contain embedded sensors. Do you want to scan for them? This is totally safe. (YES/no): Silicon Integrated Systems SIS5595... No VIA VT82C686 Integrated Sensors... No VIA VT8231 Integrated Sensors...

No VIA Nano thermal sensor... No Some Super I/O chips contain embedded sensors. We have to write to standard I/O ports to probe them. This is usually safe. Do you want to scan for Super I/O sensors? (YES/no): Probing for Super-I/O at 0x2e/0x2f Trying family `National Semiconductor/ITE'... No Trying family `SMSC'... No Trying family `VIA/Winbond/Nuvoton/Fintek'... Yes Found unknown chip with ID 0xd802 (logical device B has address 0x290, could be sensors) Probing for Super-I/O at 0x4e/0x4f Trying family `National Semiconductor/ITE'... No Trying family `SMSC'... No Trying family `VIA/Winbond/Nuvoton/Fintek'... Yes Found unknown chip with ID 0xd441 Some systems (mainly servers) implement IPMI, a set of common interfaces through which system health data may be retrieved, amongst other things. We first try to get the information from SMBIOS. If we don't find it there, we have to read from arbitrary I/O ports to probe for such interfaces. This is normally safe. Do you want to scan for IPMI interfaces? (YES/no): Probing for `IPMI BMC KCS' at 0xca0... No Probing for `IPMI BMC SMIC' at 0xca8... No Some hardware monitoring chips are accessible through the ISA I/O ports. We have to write to arbitrary I/O ports to probe them. This is usually safe though. Yes, you do have ISA I/O ports even if you do not have any ISA slots! Do you want to scan the ISA I/O ports? (YES/no): Probing for `National Semiconductor LM78' at 0x290... No Probing for `National Semiconductor LM79' at 0x290... No Probing for `Winbond W83781D' at 0x290... No Probing for `Winbond W83782D' at 0x290... No Lastly, we can probe the I2C/SMBus adapters for connected hardware monitoring devices. This is the most risky part, and while it works reasonably well on most systems, it has been reported to cause trouble on some systems. Do you want to probe the I2C/SMBus adapters now?

(yes/NO/selectively): Sorry, no sensors were detected. Either your system has no sensors, or they are not supported, or they are connected to an I2C or SMBus adapter that is not supported. If you find out what chips are on your board, check https://hwmon.wiki.kernel.org/device_support_status for driver status. I did a dmesg --clear first, tried mounting the nct6775 kernel module and printing dmesg next, but the buffer was empty. Thanks, Jurgen.

I have the ASRock B650E Taichi motherboard, but it has a different chip, I believe it is the Nuvoton NCT6796D-S.
