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 cheers, Hiren
