Mine just arrived today, thus all the posts I’ve been making… it seems to sit at a bit under 50 degrees with no load:
sudo apt install lm-sensors
sensors
produces:
Adapter: ISA adapter
temp1: +46.2 C
I’m assuming that’s the CPU, looks like the system needs some tweaks to work with lm-sensors. In any case that’s pretty hot, so I’ll be adding a northbridge heatsink soon. It’s a pity Zalman stopped making their tall passive northbridge heatsinks (the ZM-NB47J), I’ve used up all the ones I had on ODroids and the like and they’re perfectly capable of passively cooling these things.
