Interestingly, the firmware update did not seem to help with my=20 PowerMac.=C2=A0 Everything was fine after the first reboot following the = update, but after rebooting again, I got runaway fans again after a few=20 minutes. Pondering what might be different on the first boot, I noted two things: 1. The prior boot had been into OS X, so maybe it properly reset some=20 hardware where FreeBSD fails to? 2. For the first FreeBSD boot, I still had a monitor, keyboard, and=20 mouse attached from performing the firmware update in OS X. Most of the=20 time, I run this system headless. Testing #2 first, I rebooted with and without a monitor a few times.=C2=A0= =20 Every time I boot headless, I get runaway fans.=C2=A0 Every time I boot w= ith=20 a monitor attached, there's no problem.=C2=A0 I can detach the monitor af= ter=20 boot without triggering the issue. Seems like an odd linkage, but perhaps failure of the video driver to=20 initialize properly is triggering the fan issue?

I've found that rebooting has a small probability of eliminat= ing the issue, so if you can get a clean boot where the fans don't go nut= s within a few minutes, you should be OK until the next reboot. >>>>>> >>>>>> JB >>>>>> >>>>>>> On 5/26/20 3:52 PM, Sidney Holliday via freebsd-ppc wrote: >>>>>>> Hi my name is Sid I=E2=80=99m new to FreeBSD I have already insta= lled version 12.1 and have not yet loaded the desktop Gnome3 because the = fans keep going to high speed, I tried to use the POWRD utility but it lo= oks like that doesn=E2=80=99t work with this machine.
