You have been subscribed to a public bug: Current reports from `sensors` for Zen 3 CPUs: ``` PCH_CHIP_CPU_MAX_TEMP: +0.0°C PCH_CHIP_TEMP: +0.0°C PCH_CPU_TEMP: +0.0°C ```
This bug is due to the lack of Zen 3 support in Ubuntu's implementation of k10temp. Zen 3 (Ryzen 5XXX) temperature support is now ready as a part of `k10temp`: https://www.kernel.org/doc/html/latest/hwmon/k10temp.html and narrowly missed the window for mainline kernel 5.12. My understanding is it was included in 5.10, removed in 5.11 for documentation/validation reasons, then planned again after updates. With the popularity of these chips increasing, having accurate CPU temp readings is of import in Ubuntu 20.04, as this is an LTS release with support until 2025. Therefore, as we are set at kernel 5.8 at the moment, with 21.04 releasing with kernel 5.11, it may be worth pulling in the latest k10temp to fix this bug as to not delay access to vital CPU information throughout 2020.
