** this rpi4 has aluminium case heatsink and recommended-by-rpi PSU.

My rpi4/8GB has the following in /etc/rc.conf
[...]
powerd_enable="YES"
powerd_flags="-r 1"
[...]

means it'd only shift down if use was 0.00 IIUC. So in practice it never
shifts down.

in /boot/msdos/config.txt :
[...]
over_voltage=8
arm_freq=2147
sdram_freq_min=3200
[...]

results in:
[...]
% sysctl dev.cpu.0
dev.cpu.0.temperature: 72.0C
dev.cpu.0.freq_levels: 2100/-1 600/-1
dev.cpu.0.freq: 2100
dev.cpu.0.%parent: cpulist0
dev.cpu.0.%pnpinfo: name=cpu@0 compat=arm,cortex-a72
dev.cpu.0.%location:
dev.cpu.0.%driver: cpu
dev.cpu.0.%desc: Open Firmware CPU

at the time of writing:
% uptime
  4:01p.m.  up 16 days,  3:10, 5 users, load averages: 4.49, 6.47, 4.68

because it's running a poudriere build.

ssh never times out. It's running stable/13-n245223-af8d48ac4b8 built
