#239127 — smart fans

From	Emanuel Berg <moasenwood@zoho.eu>
Date	2021-08-22 02:00 +0200
Subject	smart fans
Message-ID	<COJ46-2g1-13@gated-at.bofh.it>

o/

Is there a way to have "smart fans" that only go as fast
as needed?

Or, lacking that, is there a way to manually switch them off
when one isn't using the computer?

I do

  $ sudo hibernate -v 0

but that seems to kill the Internet connection as well :(

I managed to output the GPU/CPU temperature like this

  #! /bin/zsh
  # https://dataswamp.org/~incal/conf/.zsh/misc-hw
  temperature () {
      local gpu=$(sensors -j | jq -a '.["nouveau-pci-0100"].temp1.temp1_input')
      local cpu=$(sensors -j | jq -a '.["k10temp-pci-00c3"].Tdie.temp1_input')
      echo "GPU ${gpu}C"
      echo "cpu ${cpu}C"
  }
  alias temp=temperature

Perhaps one should leave those on?

But I also have, connected to the motherboard

  fan     front low           be quiet! Shadow Wings 2  140 mm
          front high          be quiet! Shadow Wings 2  140 mm
          CPU cooling tower   be quiet! Pure Wings 2    120 mm  (2)
          rear                Corsair                   120 mm
          projector extra     fractal Silent Series R3  140 mm
  <https://dataswamp.org/~incal/ebchw/COMPUTER>

Can I reduce their speeds/turn them off from software?

TIA

It's not because you are not using the computer that it means that it
doesn't use power (and produce heat), hence why the fans work even if
your computer are idle.

Do you know what hibernate means ?

https://en.wikipedia.org/wiki/Hibernation_(computing)

Hibernation (also known as suspend to disk, or Safe Sleep on Macintosh
computers) in computing is powering down a computer while retaining its
state. When hibernation begins, the computer saves the contents of its
random access memory (RAM) to a hard disk or other non-volatile storage.

So yes it does cut your Internet connection.

It wouldn't be a good choice to turn off the fans as you'll be causing
your CPU temperature to rise and this could damage it. Even if it would
be possible, something that I have doubt. As there's some self
protection enabled in the management system.

Maybe you are playing in something you don't really master the ins and
out of the consequence of what you may do. And this is proven by the
simple sentence that *hibernation cut Internet*. Unless you have a good
reason to risk frying your CPU then leave it alone.

Or buy a system that doesn't use a fan, like the low power, low thermal
emission CPU used in laptop with only passive cooling (heatsink).

Oh, I meant to post this to the Debian user ML, not

I had an RPi3 once and it was completely quiet, at least to
the human ear - no fan. But as you see (the HDD and projector)
while I used it, the fans were on anyway. But for some reason
when you use a computer, that noise don't bug you ...

  https://dataswamp.org/~incal/work-photos/rpi.jpg

So there is no way of disabling the 120/140 mm fans that are
connected to the motherboard from software? Maybe prolong the
cables and have little physical switches (to cut power), if
such things are marketed ...

Because this

  #! /bin/zsh
  # https://dataswamp.org/~incal/conf/.zsh/misc-hw
  temperature () {
      local gpu=$(sensors -j | jq -a '.["nouveau-pci-0100"].temp1.temp1_input')
      local cpu=$(sensors -j | jq -a '.["k10temp-pci-00c3"].Tdie.temp1_input')
      echo "GPU ${gpu}C"
      echo "cpu ${cpu}C"
  }

outputs the CPU and GPU temperature, one could downgrade the
fans gradually and see what good they do - especially when one
isn't using the computer ...

How's that supposed to be relevant as a comment ?

You did post it to Debian mailing list. Did I suggest you didn't ?

You are comparing different things with no link between each other.

One (RPi) is a CPU meant for using mostly a heat sink and running at low
power, being able to modulate the speed based on load and using low
power consumption.

And the other one CPU (Intel/AMD made for desktop) is a CPU meant to be
cooled with a fan and produce much more thermal power per watt.

You compare something running with a USB power supply versus something
requiring hundred of watts of power.

The speed of your fan are set according to a thermal sensor.

If they are really loud than maybe either they are dirty or the thermal
sensor could be failing and this would make them run at full power all
the time. Other than this, they are happy as they are.

They sell desktop computer built using laptop CPU if you want something
silent. But those are pretty limited as a matter of CPU power because
CPU power means using watt of power to drive it. And those watts have to
go somewhere and this is called heat.

Maybe there's a reason why there's a hardware fan and it can't be turned
off. And that there's some safety that prevent you from frying your
system. Don't you think ? Or is it simply that you believe that we are
mostly just enjoying having a fan in the PC ?

Your computer doesn't produce nothing as mechanical work. All the energy
is converted into heat, it's somewhat only a really non efficient
heater. Energy doesn't get lost, if it's not producing mechanical work
then it means it's getting converted to heat (and some to light for the
blinking light). Calculation or whatever else is done (it's all
calculation at basic level) doesn't exist in physics, that's only
electricity running thru tiny wire and producing heat thru resistivity.

That's called "Ohm Law", the same law goes on for your electric toaster
or your coffee machine (unless is petroleum fuel that drive you coffee
machine, if so *cool*).

Even if one ain't using the computer. You seem to forget that has long
your computer is running, there's a load of background task running,
some requiring more or less processing power.

And you've been complaining that you loose network connection when going
idle, so if you keep network connection this could also mean there would
be incoming connection.

*Good luck*

?

Ah, you mean _you_ are comparing. The power supply.

> Other than this, they are happy as they are.

You mean there is no way to disable or set the speed
with/from Debian?

I'll add. the CPU in a Raspberry Pi is meant to be used in embedded
application and other stuff like a cellular phone for example. Those are
ARM type processor. Totally different from a x86/x64 based processor.

ARM are CPU used in cell phone and the latest Mac that runs without a
heat sink.

Nothing compared to a desktop PC.

And even then, there's some Raspberry Pi with a fan.

https://www.raspberrypi.org/blog/new-raspberry-pi-4-case-fan/

So even the RPi if you want more power, a fan would help. Because when
temperature rise, the CPU clock will lower, something specific to ARM CPU.

With AMD/Intel x86/x64 CPU, it's more that it won't allow to upscale the
clock if the temperature is too high inside the CPU.

Well, I used the RPi3 as my main computer for a long time.
One had to use omxplayer, a special media player, tho, and
when that run one couldn't background it and use the computer
for something else, probably because it monopolized the
resources in order to function at all.

Now on the stationary I can use mpv which is much better. (I
don't know how it is with the RPi4 in this respect.)

Other than that the RPi3 as a workstation was pretty much like
any Unix system I've used. But I prefer Debian (vanilla
Debian) to Raspbian, which I heard is now called the RPi OS.
It is a hardware-specific Debian derivative for the RPi, much
like ev3dev for the LEGO droid.

Coreboot is what you're thinking of.
Supported motherboard's list is extremely limited though.

There is a grub-coreboot package, is that it?

And how do you know if its supported?

I think I have a

  Asus ROG Strix B450-F Gaming

motherboard.

No. If you look at the output of

$ apt-cache show coreboot

you'll see that it says

"This is a dependency package for a version of GRUB that has been built
for use with platforms running the Coreboot firmware."

As that indicates, this is not / does not install coreboot itself, it
only installs a version of GRUB that knows how to interact with
coreboot.

> And how do you know if its supported?

Read the coreboot board-compatibility list, which to the best of my
ability to determine on short notice is at:

https://coreboot.org/status/board-status.html

I haven't looked in depth, but
https://doc.coreboot.org/mainboard/index.html and/or the rest of
https://doc.coreboot.org/ might be useful.

You'd need the actual, internal model number, but I suspect that that is
far too new to be likely to be (well-)supported yet.

I don't know ! Why don't you take a look yourself ?

I'm ready to help you build whatever you want. But this does not mean

This made me think, is there a FOSS "BIOS" (UEFI) that you can
install/flash to replace the manufacturer's?

As Polina says, the infrastructure should be there. If your fans
have three leads on their cable, one of them is PWM control for
fan speed.

The CPU itself has one (actually several) temperature sensors built
in, and the CPU/chipset is capable of generating the needed PWM
signals. Some software needed.

Start here [1]. Enjoy.

Yes, but ...

$ sudo pwmconfig
# pwmconfig version 3.6.0
This program will search your sensors for pulse width
modulation (pwm) controls, and test each one to see if it
controls a fan on your motherboard. Note that many
motherboards do not have pwm circuitry installed, even if your
sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm
controls. The program will attempt to restore each fan to full
speed after testing. However, it is ** very important ** that
you physically verify that the fans have been to full speed
after the program has completed.

Found the following devices:
   hwmon0 is k10temp
   hwmon1 is asus
   hwmon2 is nouveau

Found the following PWM controls:
   hwmon2/pwm1           current value: 51

Giving the fans some time to reach full speed...
Found the following fan sensors:
   hwmon1/fan1_input     current speed: 0 ... skipping!

There are no working fan sensors, all readings are 0.
Make sure you have a 3-wire fan connected.
You may also need to increase the fan divisors.
See doc/fan-divisors for more information.

                       ^^^^^^

Well?

This would be the first thing to clear. If your hardware
doesn't play along... game over :-/

Yeah, but if so, why doesn't it?
