Temps/pwm Survey

[romtorwator]

it seems that no additional reinvention is required,
in the case, chassis fan is not connected yet, heatsink 30mm with fan, in the room there is no air conditioning, immobile air, air temperature +25С
My board in SOHO NAS server mode, Samba/NFS/Apache/MySQL/Transmission/OpenVPN,
for a personal internet site, torrent download, Veeam backup of three computers, local network video playback, Remote access to the local network.
the second day I observe a temperature of +39...+ 42C
date, time, cores frequency, temperature, PWM, in parts of logs:
