[-- Attachment #1 --] Hi, I just installed FreeBSD on my laptop, and everything went smoothly, except one thing that my laptop seems to be a little warm and noisy (due to the fans) even when it's idle. Following some steps on other forums, I tried the following: $ sysctl 'hw.acpi.thermal' This gives me an 'unknown oid' error. $ sysctl -a | grep temp This gives no results. After running # kldload coretemp and retrying: $ sysctl -a | grep temperature I do get the CPU temperature values: dev.cpu.15.temperature: 51.0C dev.cpu.13.temperature: 50.0C dev.cpu.11.temperature: 50.0C ... All this is when the laptop is absolutely idle with just the shell running in the TTY. I can confirm that # top shows the same (CPU 100% idle). I'm not sure what is going wrong and would be grateful for any help. Thanks!
