High temperature and fan speed

I tried these configurations but the i7z output is always 100% C1:

Just change one variable at a time, and be clear about whether you've rebooted since changing rc.conf, or cycled AC/battery power (or run 'service power_profile') to get cx_lowest changed systemically, rather than temporarily.

I suggest leave powerd{,++} out of it for the moment. I think you'll want it, but that getting AC power C-state right should make a big difference to your heating issues first.

Try performance_cx_lowest=C2 or C3, but definitely not C1 (unless running as a busy server with steady load, which I expect you're not).

/etc/rc.conf:

Code:

powerdxx_enable=YES powerdxx_flags="-n adaptive -a adaptive -b adaptive -m 800 -M 1600"

Good test for later. I'm not sure if powerdxx is aware of CPUs that vary speed per core yet (anyone know?)

I can see powerd hasn't changed, so does poking just cpu.0.freq still work (does anyone know?)

Code:

performance_cx_lowest=C1 economy_cx_lowest=C3

Did you test that on battery?

chrislg said:
Code:

performance_cx_lowest=C1 economy_cx_lowest=C7

See above, seems like Linux' term for FreeBSD's "Cmax" so better to use that here.

chrislg said:
and in /etc/sysctl.conf:

Code:

dev.cpu.0.cx_lowest=C3 dev.cpu.1.cx_lowest=C3 dev.cpu.2.cx_lowest=C3 dev.cpu.3.cx_lowest=C3

That may work at boot, but later depends, entirely I think, on the setting of sysctl hw.acpi.cpu.cx_lowest, which is exactly what /etc/rc.d/power_profile sets.

Have a look at that script, noting that the other thing it can set on power changes is {performance,economy}_cpu_freq. The default is "NONE", i.e. don't change cpu.0.freq, and best not set freq here, it will mess with powerd later.

In short: try C2 and C3 without powerd, at idle, watching with i7z and the relevant sysctls, under both idle and some load, to see how it affects heat/fans?

chrislg · Feb 19, 2023

So I commented out the powerdxx in /etc/rc.conf and the /etc/sysctl.conf settings and used first:

Code:

performance_cx_lowest=C2
economy_cx_lowest=C3

I rebooted.
On battery the temperature was 50-60 and on AC reached 70-75, then disconnected AC and temp reduced to 55-60.

Then I used:

Code:

performance_cx_lowest=C3
economy_cx_lowest=C3

I rebooted
Both AC and battery temperatures were 45-55 and the fans were noisy but less noisy compared to the normal behaviour.

The i7z showed again 100% C1 and 0% other states in all the experiments. Load was minimum and temp at idle

What does your configuration files look like?
Are these states by default on your PC or did you change them?

Relevant to this issue,
/etc/rc.conf:
performance_cx_lowest="Cmax"
economy_cx_lowest="Cmax"
powerd_enable="YES"
powerd_flags="-a adp -b adp -n adp"
# (I haven't tuned powerd for X on this laptop yet)

/etc/sysctl.conf (nothing)

/boot/loader.conf
coretemp_load="YES"
cpuctl_load="YES"

chrislg said:
My laptop is almost always on AC and my battery is set to 50-55% in Bios

Fair enough.

chrislg · Feb 19, 2023

I think that the output of i7z is different from the usage output of this command

Code:

sysctl dev.cpu | grep cx

Yes, exactly. AC or battery?

Rather than unquoteable images, plus some more useful data, perhaps:

Code:

sysctl dev.cpu | egrep 'cx|freq|temperature' > textfile

then can paste textfiles into messages. ('temperature' wants coretemp loaded)

On mine and all older intel CPUs, only dev.cpu.0 has .freq and .freq_levels ... is that true also of yours?

Anyway, it's handy building a script that can print out core settings and stats for your box, date/time stamped, e.g. my 't430stat' above. You could include bits scraped from i7z as well of course.

The dmesg output in case it is useful. I will try the other commands soon.

I have been following this thread with interest as - I think - I have the same issue with my laptop, although this is a slightly different model of Dell: Precision 5550.

Bash:

sysctl hw.model hw.ncpu
hw.model: Intel(R) Core(TM) i7-10875H CPU @ 2.30GHz
hw.ncpu: 16

After booting it up I will always notice slowly increasing temperature and fan noise.

i7z shows C1% as ~99 for most cores, whereas it is ~1-4 for C0%, and 0 for C3% and C6%.

That said, tonight for the first time ever, I think - could be my imagination - that the temperature has stabilised at a lower range of around 50.0C - 53.0C whereas it typically used to go higher:

Bash:

sysctl dev.cpu | egrep 'temperature' | sort -n -k 3 -t '.'
dev.cpu.0.temperature: 51.0C
dev.cpu.1.temperature: 51.0C
dev.cpu.2.temperature: 51.0C
dev.cpu.3.temperature: 51.0C
dev.cpu.4.temperature: 50.0C
dev.cpu.5.temperature: 50.0C
dev.cpu.6.temperature: 50.0C
dev.cpu.7.temperature: 49.0C
dev.cpu.8.temperature: 49.0C
dev.cpu.9.temperature: 49.0C
dev.cpu.10.temperature: 49.0C
dev.cpu.11.temperature: 49.0C
dev.cpu.12.temperature: 49.0C
dev.cpu.13.temperature: 49.0C
dev.cpu.14.temperature: 48.0C
dev.cpu.15.temperature: 49.0C

I think the most recent config change I made was adding this line to /boot/loader.conf:
cpuctl_load="YES"

... but I could be wrong about that.

I'm dual booting with Fedora Linux, and there the temperature and fan noise never seem that noticeable. (I will attempt to install i7z to confirm.)

Apologies if I'm just confusing the issue with this post. Happy to go away and create my own thread instead.

Thank you for posting your experience. I thought I was the only one with this type of issue. I will try your suggestion and I will post the results here soon

dbdemon · Feb 21, 2023

Thanks chrislg for letting me share my problem in your thread.

I managed to install i7z on Fedora and I can confirm that the core temperatures there are much lower. Looks like 35C-37C right now after the machine was suspended for a while earlier, although they were around 40C-42C just after booting up and having run FreeBSD just before that. The fan is also not audible.

What temperatures did you have before the change that you noticed?

chrislg · Feb 21, 2023

cpuctl_load="YES" made no difference

Still 55-60 Celcius on battery at idle. Compiling kde from source in Manjaro rises temperature up to 55-57..
Maybe our CPUs is not that good supported by FreeBSD.

Maybe I should give up on this Laptop and try on an older one...

Afraid I didn't make a record of it, so I don't remember. But I might change it back and see if it gets worse, and if so, what temperatures I get.

Just to confirm that with Fedora and "normal" use (web browsing, Slack client, Evolution, terminal etc.) the core temperatures are hovering around 40C-42C according to i7z.

That is what I'm suspecting as well. Not the end of the world for me as I don't actually own this laptop as such. I'd rather go and buy a laptop for myself that I know will play nice with FreeBSD.

chrislg · Feb 21, 2023

I wonder if it is only the case for laptops or generally other hardware. What is the typical temp profile of systems running FreeBSD 24/7 or even raspberry pi running this OS

dbdemon · Feb 21, 2023

Looking more at core temperatures tonight. Looks like I was wrong - cpuctl doesn't seem to have any impact on it.

I did kldunload cpuctl shortly after boot-up. The temperatures rose to about 60C, then the fan kicked in and they went down to around 55C. Later the fan got louder, and the core temperatures were around 46C-49C with the fan still being loud. I was sitting with the laptop literally on my lap, and when I changed position so that there was less surface contact between my lap and the laptop, the temperatures dropped further to 42C-45C, and the fan now being quieter again ...

Edit: And after rebooting into Fedora, the core temperatures fell down to about 38C-40C, despite lots of surface contact between lap and laptop.

Red herring alert.

I showed cpuctl_load in my /boot/loader.conf because powermon requires it. It has nothing to do with controlling temperatures.

powermon has utility for seeing power use split over Package, Uncore, x86 cores and GPU; seeing GPU power use was the point here.

The dmesg output in case it is useful. I will try the other commands soon.

It was indeed, after I managed to copy and paste it to a file.

Now I find quoting your post chops off the end of it, ie it's too big. Next time for files over maybe a few KB, use the 'attach a file' method?

https://wiki.freebsd.org/TuningPowerConsumption

Bingo! I hadn't realised that it had been kept so up to date; see the 'Info' page there.

Alexander (mav@) reworked FreeBSD's event and time counters code for 9.x and since, but I see the coverage of the latest Intel Speed Shift / hwpstate stuff there too, which I think may be the key to your issues ... also seeing those in your dmesg.

Firstly I suggest recording sysctl -a | egrep 'hwpstate|$etc' under varying conditions, to see if / how it may vary, before messing with it.

Then mess with it, severely then somewhat, to watch heating and responsiveness on AC / battery, idle / moderate / full load ...

If this works, it lends itself to dynamic load / power control like powerd{,xx} ... maybe someone's working on it already, I'm well out of touch.

In any case, I reckon treat that wiki post as the Good Oil until anything better arrives.

Too soon to give up yet. If need be we can try dragging mav@ etc into the forums.

I tried in /boot/loader.conf:

Code:

machdep.hwpstate_pkg_ctrl=0

and in /etc/sysctl.conf:

Code:

dev.hwpstate_intel.0.epp=100
dev.hwpstate_intel.1.epp=100
dev.hwpstate_intel.2.epp=100
dev.hwpstate_intel.3.epp=100
dev.hwpstate_intel.4.epp=100
dev.hwpstate_intel.5.epp=100
dev.hwpstate_intel.6.epp=100
dev.hwpstate_intel.7.epp=100

The temperature decreased 10-15 degrees Celcius in both AC and Battery while using cooling pad and was 45-49 but not exceeding 50. The fans were still very loud... But the positive thing is that the temp decreased noticeably.
By no means at Manjaro's level but I thing I am asking a lot at this point haha

I should also try this in 13.2-Beta2.
What if I disable Intel Speed Shift in BIOS?

Well that's a real win, but the fan(s?) seem to be not well-coupled to CPU temps. What ambient temps does it experience where you are?

Does your cooling pad make much difference? Re the bit about mention of on/off lap by dbdemon.

Important: Were those .epp sysctls set to 50 originally? Or what? [I'm on 12.4-R here, before hwpstate_intel]

Does 'sysctl -a | grep thermal' show anything? If hw.acpi.thermal is not there, maybe there's no fan control available on your Dell? Anything in BIOS re fans?

Any news on FreeBSD support from the Dell side, forums etc? A pity that there's no acpi_dell.ko

Clutching at straws here ...

chrislg said:

Well you'll likely get better support than running 14, esp. here in forums where it can be considered 'naughty'. But I doubt it would be different in this respect.

chrislg said:

You could try, but I doubt you'd get lower temps, or consequently slower fan(s?), but then powerd could maybe do its thing better at idle.

Anyway, have you tried powerdxx again since the 15°C temp drop? I'm curious if it can deal with Intel Speed Shift with different freqs on cpu.N threads (yet) ...

OTOH, don't let my insatiable curiosity waste your time <&^}=

cheers, Ian

chrislg · Feb 22, 2023

Yes I will test some things. Btw today I upgraded in Manjaro from kernel 6.1.12 to 6.1.13 and I noticed increased heat (55-60) and fans going crazy.
I downgraded the kernel and things are as before ...
I had some issues with previous kernels too. It is weird with my laptop ...

Yes the above measurements were with powerdxx and hiadaptive.
Cooling pad makes no difference in fans noise but the recorded temperatures are using it

sysctl -a I grep thermal gives no results

chrislg said:

Hmm, well digging down into powerdxx(8) to the CAVEATS I see:

"Unlike powerd(8), powerd++ refuses to run if the frequency control driver is known not to allow user control of the CPU frequency (e.g. hwpstate_intel(4) )."

Which makes sense unless and until powerdxx is taught to play with hwpstate_intel sysctls. Or powerd is.

I've installed v0.4.4_1 and checked both github.com &
lonkamikaze.github.io, but can see nothing newer.

So perhaps there will be a reported powerdxx failure in /var/log/messages if you missed seeing it?

Of course you can disable ISS and go back to est(4) and so use powerd{,xx}. Maybe worth trying?

It would be good to know the boot defaults on yours for the hwpstate_intel sysctls?

Have you tried changing them while running? It'd be game over if you couldn't.

If the bootup defaults are 50 then 0 should make temps even higher. OTOH, if they were 0 then that would indicate poor defaults, but maybe Dell's defaults are determined by a performance / economy setting in BIOS?

I've found sysutils/stress handy for load testing. E.g. with yours
% stress -c 8 -t 120
will fully load all CPU threads (0% idle) for 2 minutes, and -c 4 will give 50% total load.

I guess it's a bit tedious debugging both Dell and FreeBSD setup for these newer CPUs, but let's hope it may ease load for others.

I'm wondering whether to email an invitation to kami@freebsd.org at this stage, but it's your thread ...

chrislg said:

Are they any higher without?

chrislg said:

Pity, guess they handle it in (or behind) BIOS code.

As it stands, I'm out of ideas beyond testing different combinations. No doubt you'd like to be getting on with other things. Cheers

High temperature and fan speed
