Hello @codrut, Welcome to the community!

The Edge 2 does get a little warm under basic load, the chip does have a relatively higher TDP compared to other ARM64 SoCs. ~12W compared to ~5-6W on the A311D of the VIM3. So it is normal to see the fan turn on a little early, but it is nothing out of the normal.

The provisioned cooling system is most capable of handling it at high system usage, I’ve tried stress testing it before, and it doesn’t go past 72-76C. so it doesn’t throttle either.

hope that solves your query

Cheers

Thanks for replying. The only thing that is annoying is the fan noise. I will remove the case an try with this fan:

It’s 40x40 mm instead of 37x47 mm but maybe it will work.

@codrut I would recommend setting your fan to medium speed level, or you could write a small shell script and a systemd service to turn on the fan but limit the speed to the medium setting, giving you flexibility of being silent when idle and not too loud when under load.
