Just for curious minds:

Afternoon and evenings bring direct sunlight to where the machine is.
And I guess that is showing? probably?
# sysctl dev.cpu | grep temp
dev.cpu.0.temperature: 16.8C
dev.cpu.1.temperature: 16.8C
dev.cpu.2.temperature: 16.8C
dev.cpu.3.temperature: 16.8C
dev.cpu.4.temperature: 16.8C
dev.cpu.5.temperature: 16.8C
dev.cpu.6.temperature: 16.8C
dev.cpu.7.temperature: 16.8C
