[CCing Modulok whose reply (probably accidentally) reached me directly and not the mailing list] Thank you both for your responses! I tried what you suggested but Powerd doesn't seem to resolve the issue. I already had it enabled /etc/rc.conf: powerd_enable="YES" though not with the specific flags you mentioned powerd_flags="-a adaptive -b adaptive -n adaptive" Even after setting the flags though, and restarting powerd / rebooting, I can still observe that slight distinctive warming/fan noise. Is there anything else that might be causing this? I remember I once had the same issue with a Linux distro on this same laptop, and that was because this laptop has Intel integrated graphics along with a separate NVIDIA GPU and the correct drivers were not in place. Though that was when I was using a graphical environment, while on FreeBSD here I am currently just using the TTY. Therefore I initially assumed that this might not have anything to do with the warming. Thanks again for your time.
