Temperature info is high while appliance is rather cool
-
Update: What I did notice under system activity is that the pfblocker updater seems to be running on CPU1 at 100% even though the update only runs for 3 minutes and is then done. Is this normal?
-
@Klaus2314 I believe there is at least one other thread about check_reload_status getting stuck at 100%, relatively recently.

@SteveITS Ah interesting, thanks! That thread reads like it's probably the problem. I'll do some digging.

@SteveITS So it turns out that my box had the PowerD turned off. I have now turned it on and set it to adaptive mode and temps went down immediately. This doesn't explain why the housing is cool when the CPUs are at 80°C+ but it seems to have fixed the high CPU frequency. I'll see how this goes the next days.
Thanks for pointing me to that thread!

I'm running 2.7.0 on a Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz mini computer
If it is one of those little chinese enclosures you should open it and reapply some thermal paste and check the contact to the heatsink. (If you search this forum you find similar indications)

Yup that^. Check the CPU is actually attached to the heatsink/case in a useful way. A CPU running at 25% should not heat up that much IMO.

@stephenw10 Yeah, will do when I get a chance. Applying those system tunables made a HUGE difference. Temps are now down to 30°C area. Thank you all!!
Before and after. You can see the huge dip from 70+ to even 10 below the old average of 40°C. Also the CPU frequency is now WAY lower.
The hung updater running at 100% on one CPU has cleared after a reboot of pfsense. I guess that's a different issue. -
The tunables to tune Speed Shift?
Yeah, running the CPU at a lower frequency with no significant actual load difference really shouldn't make anywhere near that sort of temp difference.
Additionally you should be able to run any system at 100% CPU load without it getting dangerously hot.
-
@stephenw10 Yeah, PowerD seems to be broken in freeBSD14 so I followed the advice in the thread that was recommended earlier in this thread. All good now. Turning on PowerD didn't fix it.
-
Powerd (with Speedstep) works fine but only if you disable SpeedShift since it takes priority. But you should use Speedshift on any CPU that supports it, it's much better in almost every way.
