Does exist a stable, old, low temperature version of Armbian for OPi1

[psygnosis]

Hi,
I have 2 OPi1 that I want to use for some test projects.

One project consist just on PiHole, the other one on Tailscale.

Since with newer kernel I have high temperature on idle (like 70°C) can you advice me an old version that maybe has a "better" thermal management?
Thank you so much, if I'm saying something stupid please tell me, maybe I just need to tune something like disable hdmi, gpu etc...

@psygnosis Which version of Armbian and os are you running? Yesterday I loaded  current noble on a test system and I just noticed that it is running hot (45) even with a significant heat sink.  Another operational system that is running current bookworm runs much cooler (32). If you are running noble, could I ask you to try bookworm to see if there is a difference.

 

I will load up my test system with bookworm to check also.

It looks like my test system just runs a little hotter, probably because it is in a case. I took the SD card out of the test (hot) system and put it in the operational system and the operational system still ran cool.  So it is not the os. Changing to noble from bookworm made no difference in the running temperature.

@psygnosis

Can you run "armbianmonitor -m" (as root) to see what the processor speed and system load is when you are experiencing the high temperature.

 

I found an old distro and loaded it on my test system and the temperature did not change:
