I have installed lm-sensors and run ‘sensors’:
Adapter: ISA adapter
Also, a near-question’s answer says look at ‘/sys/class/hwmon/hwmon0/temp1_input’:
user@starfive1:~$ cat /sys/class/hwmon/hwmon0/temp1_input
Clearly the same sensor, but what one? CPU temp? Board temp?
Too lazy to find and slog through whatever doci there is… Thought someone might already know.
I would say the JH7110 RISC-V SoC temperature.
My search for “kernel hwmon StarFive JH7110” resulted in the following.
Kernel driver sfctemp
Thank you very much. That makes a lot of sense to be the SoC’s temp.
On a second StarFive 2, I have the “WayPonDEV Acrylic Case for VisionFive2 RISC-V Linux Single Board Computer (with Heat Sink)” from Amazon (actually by Youyeetoo). Perfect case. Comes with a not-so-quiet 5v fan that snaps onto the board over the SoC, and plugs into the 5v fan power socket. That system runs MUCH cooler, but it runs off an SD card, while the 53.4 degree C has no case or fan and runs off an M.2 NVMe (which I’m sure is tranferring heat to the SoC).
