By default, on Proxmox kernel 6.8.12-15-pve, only CPU\/NVMe temperatures are available. sensors-detect —auto<\/i> finds only coretemp, no Super I\/O support. The hardware (Nuvoton NCT6798D) requires the NCT6775 driver, which is not included in this kernel build.<\/p>\n

Driver patching and installation<\/h2>\n
    \n
  1. Install build tools and kernel headers<\/li>\n<\/ol>\n
    sudo apt update\r\nsudo apt install build-essential\r\nsudo apt install proxmox-headers-$(uname -r)<\/code><\/pre>
    Preparing to unpack ...\/proxmox-headers-6.8.12-15-pve_6.8.12-15_amd64.deb ...\r\nUnpacking proxmox-headers-6.8.12-15-pve (6.8.12-15) ...\r\nSetting up proxmox-headers-6.8.12-15-pve (6.8.12-15) ...<\/code><\/pre>
      \n
    1. Download the NCT6775 driver<\/li>\n<\/ol>\n
      ⚠️ Do not use the abandoned killghost fork.
      \nInstead, use the damix1\/nct6775 repo, which can be patched for newer chips.<\/p>\n
      git clone https:\/\/github.com\/damix1\/nct6775.git \/root\/nct6775\r\ncd \/root\/nct6775<\/code><\/pre>
        \n
      1. Patch for Nuvoton NCT6798D support<\/li>\n<\/ol>\n
        Edit nct6775.c<\/i>. Extend the enum:<\/p>\n
        enum kinds { nct6106, nct6775, nct6776, nct6779,\r\n             nct6791, nct6792, nct6793, nct6795,\r\n             nct6796, nct6798 };<\/code><\/pre>
        Add names:<\/p>\n
        static const char * const nct6775_device_names[] = {\r\n    "nct6106", "nct6775", "nct6776", "nct6779",\r\n    "nct6791", "nct6792", "nct6793", "nct6795",\r\n    "nct6796", "nct6798",\r\n};\r\n\r\nstatic const char * const nct6775_sio_names[] __initconst = {\r\n    "NCT6106D", "NCT6775F", "NCT6776D\/F", "NCT6779D",\r\n    "NCT6791D", "NCT6792D", "NCT6793D", "NCT6795D",\r\n    "NCT6796D", "NCT6798D",\r\n};<\/code><\/pre>
        Add detection case:<\/p>\n
        switch (val & SIO_ID_MASK) {\r\n    ...\r\n    case 0xd42:   \/* NCT6798D *\/\r\n        sio_data->kind = nct6798;\r\n        break;\r\n}<\/code><\/pre>
        This minimal patch makes the driver recognize NCT6798D.<\/p>\n
