FreeBSD on the Aoostar WTR Pro NAS: 11 watts and a noisy fan
FreeBSD on Aoostar WTR Pro NAS

I tried NetBSD, OpenBSD, and FreeBSD on the Aoostar WTR Pro Ryzen NAS. FreeBSD 15.1 idled at 18W, but after loading amdtemp, setting C-states to C3, and disabling unused PCI power, it dropped to 11W. The fan is annoyingly loud by default, but BIOS tweaks can quiet it. Linux managed 8W, but FreeBSD is my target.
The fan is quite noisy by default and produces a low-pitched sound. Also, I don’t know how to describe it but you hear the metallic case in that sound.
