Assunto: [DNG] Devuan 3 running hot
An upgrade to Beowulf went very smoothly but since upgrading I notice
that the fans are always running. Although the air temperature is about
25°C the cores seem to run much hotter than necessary, pushing 70°C or
hotter. The system is not really under any load. What should I be
looking at to make corrections?
