I installed Linux Mint 17 Cinnamon over Windows 8 recently on an Acer Aspire E1-570. http://www.acer.com.au/ac/en/AU/content/model/NX.MEPSA.004 Everything seems to be working fine, however I notice that my fan seems to be on at high speed a lot of the time. Can someone please tell me definitive troubleshooting steps that are relevant to this distro. Also if there are commands that I can run to get the relevant system information required to troubleshoot the issue it would be great to know these too. **Edit** In case it is relevant, the screen brightness applet control wasn't working so I followed steps below - perhaps that altered something? me@computer ~ $ ls /sys/class/backlight/ acpi_video0 intel_backlight sudo touch /usr/share/X11/xorg.conf.d/20-intel.conf sudo gedit /usr/share/X11/xorg.conf.d/20-intel.conf and then added this to the file: Section "Device" Identifier "card0" Driver "intel" Option "Backlight" "intel_backlight" BusID "PCI:0:2:0"EndSection http://itsfoss.com/fix-brightness-ubuntu-1310/ Sensors also seems to be mentioned in other posts so I typed it into the command and this was the output: me@computer ~ $ sensors coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +44.0°C (high = +87.0°C, crit = +105.0°C) Core 0: +44.0°C (high = +87.0°C, crit = +105.0°C) Core 1: +44.0°C (high = +87.0°C, crit = +105.0°C) **More System Information** me@computer ~ $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor ondemand me@computer ~ $ inxi -Fxz System: Host: computer Kernel: 3.13.0-24-generic x86_64 (64 bit, gcc: 4.8.2) Right-click > "Open image in new tab" to see image at full size.

I live in my car and it gets HOT in the summer. I've noticed when the temperature rises above normal room temperatures (like ~72f) my laptop proportionally starts to slow down to the point its unusable above 90f. I use Ubuntu and was wondering if anybody had any tips or suggestions to essentially 'overclocking' my laptop (a Dell precision 5520) to be more performant at high temperatures?

I would like to change the fan speeds on my PC. In the Asus BIOS settings, this is possible with PWM and DC (three of them are connected with 4 pins), but the running operating system seems to have problems doing the same. The two I want to change manually have the names CHA_1FAN and CHA_2FAN on the motherboard. > cat /etc/sensors3.conf | grep -i fan # Fans label fan1 "PSU Fan" label fan2 "CPU Fan" label fan3 "System FAN2" label fan4 "System FAN3" label fan5 "System FAN4" # Fans label fan1 "CPU Fan" label fan2 "System FAN2" label fan3 "System FAN3" label fan4 "System FAN4" label fan7 "PSU Fan" > hwinfo | grep -i fan acpi-fan: /devices/platform/PNP0C0B:03 acpi-fan: /devices/platform/PNP0C0B:01 acpi-fan: /devices/platform/PNP0C0B:04 acpi-fan: /devices/platform/PNP0C0B:02 acpi-fan: /devices/platform/PNP0C0B:00 acpi-fan: module = fan type = "", modalias = "acpi:PNP0C0B:", driver = "acpi-fan" type = "", modalias = "acpi:PNP0C0B:", driver = "acpi-fan" type = "", modalias = "acpi:PNP0C0B:", driver = "acpi-fan" type = "", modalias = "acpi:PNP0C0B:", driver = "acpi-fan" type = "", modalias = "acpi:PNP0C0B:", driver = "acpi-fan" E: DRIVER=acpi-fan E: DRIVER=acpi-fan E: DRIVER=acpi-fan E: DRIVER=acpi-fan E: DRIVER=acpi-fan [ 0.062442] rcu: Adjusting geometry for rcu_fanout_leaf=16, nr_cpu_ids=4 fan 20480 0 - Live 0x0000000000000000 Driver Status: thermal,fan are active Driver Activation Cmd: "modprobe thermal; modprobe fan" > sudo pwmconfig [sudo] password for root: # pwmconfig revision $Revision$ ($Date$) [...] /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed heimchen@DESKTOP-G0NG8DL / > The system is OpenSuse Leap 15.5 and lm-sensor does not seem to be installed. I tried downloading it from source and compile it, which worked but there is still nothing with this name on my disk.

What are the commands to find out fan speed and cpu temp in linux (I know lm-sensor can do the task). Is there any alternative for that?

I built a machine using an [ASUS TUF GAMING B650M-PLUS](https://www.asus.com/br/motherboards-components/motherboards/tuf-gaming/tuf-gaming-b650m-plus/) motherboard and a Ryzen 7 8700G CPU. Linux installed with no problems, but I am missing fan control and monitoring. Under Windows, I use ASUS software to do stuff like setting fan curves and monitoring fan speeds: What I have tried: * pwmconfig doesn't find any fans. * sensors-detect fails to find anything but spd5118 (RAM temperature, I believe), k10temp (CPU temperature), amdgpu and NVME temperature. * [CoolerControl](https://gitlab.com/coolercontrol/coolercontrol) doesn't find any fans, either. I keep finding stuff about fan control in ASUS laptops, which isn't the case. What tools can I use under Linux to manage CPU fans? Right now, I need to reboot and enter Setup, which is very impractical.

As my CPU cooler fan broke on a setup with older hardware, I had to replace it with a similar fan, which unfortunately is pretty noisy. I am using the following system: - Mainboard Gigabyte F2A88X-Up4 - CPU AMD A10-7850k radeon r7 - Debian GNU/Linux 9 (stretch) 64-bit The fan is permanently running at 3770 RPM and I am looking for a way to manually reduce the speed. There is an option in the BIOS to set the fan to a "silent" mode, but it does not have any effect. I then installed

-sensors

and

. Running the sensors I get the following output:

-pci-00c4

                       (crit = +80.0°C, hyst = +79.0°C)

I then ran the fancontrol configuration script with

:

the following devices:
   hwmon0 is it8620
   hwmon1 is k10temp
   hwmon2 is fam15h_power
   hwmon3 is radeon

Found the following PWM controls:
   hwmon0/pwm1           current value: 0
   hwmon0/pwm2           current value: 0
   hwmon0/pwm3           current value: 0
   hwmon0/pwm4           current value: 255
   hwmon0/pwm5           current value: 255

Giving the fans some time to reach full speed...
Found the following fan sensors:
   hwmon0/fan1_input     current speed: 3792 RPM
   hwmon0/fan2_input     current speed: 0 ... skipping!
   hwmon0/fan3_input     current speed: 0 ... skipping!
   hwmon0/fan4_input     current speed: 0 ... skipping!
   hwmon0/fan5_input     current speed: 0 ... skipping!

So I am trying to reduce the speed of

/fan1_input

. Running the test, which did not stop my CPU fan, I got the following result:

pwm control hwmon0/pwm1 ...
  hwmon0/fan1_input ... speed was 3792 now 3750
    no correlation

No correlations were detected.
There is either no fan connected to the output of hwmon0/pwm1,
or the connected fan has no rpm-signal connected to one of
the tested fan sensors. (Note: not all motherboards have
the pwm outputs connected to the fan connectors,
check out the hardware database on http://www.almico.com/forumindex.php) 

Did you see/hear a fan stopping during the above test (n)?

Based on this result I assume that I cannot control my CPU fan with

? Or is it possible to write a manual configuration for the fan in

/etc/fancontrol

despite the previous output? I would appreciate your feedback.

My cooling system isn't functioning properly on NixOS. I checked the hardware monitor on MSI motherboard but I can't see anything which allows me to adjust fan settings. how do I create a custom systemd service to control fan speeds based on temperature?

I've got a USB enclosure for five 3.5" drives, but not only is the fan very loud, it also cools idle drives down to under 30°C, which according to data floating around the Internet increases chances for drive failure. Is it possible to turn this fan off and on? Then I could write a script to keep drives in a safe range of temperatures. More details on the enclosure: * 9558U3 from Orico * USB3.0, JBOD * IEC (power) connector

I'm running Ubuntu 20.04 on a Thinkpad T14s. When I push the CPUs hard, i.e. with stress-ng --cpu 8 --tz -t 60, I watch the core temps spike to 90°C before I panic and stop the stress test. The fan will start eventually, but not nearly soon enough, and from experiments with lesser stress levels it doesn't seem that the fan will be able to dump enough heat anyway. I have had some good luck using thinkfan to make the fan more responsive, and that buys me some nice wiggle room at medium-high temps, but it doesn't make enough of a difference at those high spikes. I also installed cpupower-gui. It shows me that my system is already running in the powersave mode, with a max CPU speed of 4900 MHz. If I bring down the CPUs to around 3400 MHz, the system seems to stabilize quite nicely at about 70°-75° at full load with or without thinkfan. (It's a little warmer without thinkfan.) So, I've got a solution, but I'm unhappy with it; it seems that just permanently capping my CPUs isn't supposed to be the right answer. It is my very limited understanding that the intel_pstate driver is supposed to be implementing thermal control. I don't know how to verify if it is doing its job or not; from a functional practical perspective, it doesn't seem to be. My questions: is there a better solution than pegging the CPU speed as I've done? And am I better off running with more aggressive fans via thinkfan, or should I drop the CPU power further and stick with the built-in auto fan curve?

I am facing issues with Thinkpad T410's fan. Now and then my fan stops working (meaning 0 rpm). Long time, the only solution for me was to shutdown (not to restart, instead power off) the system and then boot again. (Which is, what you can guess, not a good solution. Sometimes I even had to cancel cpu-heavy tasks, to avoid data corruption, because of the systems rescue shutdown, when the temp goes higher than 100 °C.) I found out that going in suspend mode also helps bringing the fan back to work. I would like to know which processes are started when the computer is "coming back" from suspend mode, so I can force the fan to start again without even going to suspend mode. To make sure: I don't want to control the fan itself, but I want it to "restart" manually.

I have a Dell XPS 15 9500. I have been happily using 18.04 but keep getting told I need to update to 20.04. I've upgraded, but now the fan seems to be running high pretty much all the time, even when the computer is doing nothing / asleep. Is there anything I can do about this?

In **Debian 12** (bookworm: testing-weekly): Installed **auto-cpufreq** and thermald, with auto-cpufreq.conf while on **charger**: governor = performance scaling_max_freq = 1900000 turbo = auto Thought it is conflicting with some other tools. So, **removed** all other tools: tlp cpufreq cpupower acpi acpid acpi-support linux-cpupower cpufrequtils cpulimit Hardware (Apple: amd64, 16 GB RAM, 8 CPU) limit: 800 MHz - 2800 MHz After reboot, everything (CPU Freq, Temperature, etc.) stays within limits, as set in auto-cpufreq.conf. But, **AFTER Hybrid Sleep**, things go out of control: (CPU Freq near 3800 MHz, Temp 90℃, Fan 4600 RPM). What am I missing?

When I play games on Linux then the GPU Fan gets very loud because the automatic fan control sets the fan speed to 100% when GPU reaches 80 degrees which is very annoying. This problem doesn't exist on WIndows, just Linux. I want to set my own fan curve with tools like [GreenWithEnvy](https://gitlab.com/leinardi/gwe) or [nfancurve](https://github.com/nan0s7/nfancurve) and this actually kind of works for a short time but then it seems as it suddenly gets overridden again by the built-in fan control. I can even reproduce this with the manual fan control in nvidia-settings: I check the *Enable GPU Fan Settings* checkbox and then move the slider to 50% and the fan responds correctly: But after some time the checkbox disables itself and the fan stops. This happens much faster when I actually start some game or even a WebGL demo in the browser. In *nvidia-settings Configuration* there is a setting for a *Thermal Monitor* timer but disabling it doesn't help: I can see that this timer definitely has an effect. When it is enabled then the manual control is reset back to automatic control exactly after the configured number of milliseconds. When I disable the timer then this does not happen any more at specific times but instead it happens sporadically after some random time when actually it shouldn't happen at all. I'm out of ideas here. Any tips? System info: * Debian 11 * NVidia RTX 2080 Super * NVidia driver 525.60.13 * Set Option "Coolbits" "4" in *Xorg.conf*

How can I adjust fan speed according to hard drive temperature via Fancontrol?

My server supports IPMI, so I can run a script like this: ~~~ fanspeed() { # 0 C => 10, 55 C => 10, 65 C => 100 sensors -j | jq '[.[]["temp1"]["temp1_input"]] | (max-55)*(100/(65-55)) | if . 100 then 100 else .|floor end end'; } autofan() { setspeed() { ipmitool -I lanplus -H drac -U root -P password raw 0x30 0x30 0x02 0xff $@ } while true; do fanspeed=fanspeed printf "$fanspeed "$(setspeed $fanspeed) sleep 1 done } ~~~ This keeps the CPU temp 55 C. But this sounds like a job for fancontrol. Can fancontrol use IPMI to control the fan?

I am trying to boot AntiX LiveCD on my old Toshiba A200 laptop with 2 GB of RAM. But when I accidentally launched the "sensors" in the terminal, I saw that the CPU temperature was 70°C! I turned off the laptop and turned it on again, and the fan revved up to the maximum. It turns out that antiX stops the fan? What should I do in this case?

I have an Intel i3 mini desktop pc, which is used for home server, mainly for Plex. When a user requires certain kind of video transcoding, the machine spins up its fan very loud, instead of it's otherwise really quiet mode. I am looking for some easy to set up instructions, which allow me to use the machine silently whatever happens on it. I don't care if it can't serve my users well enough (then they have to choose direct streaming for example), my highest priority is to reduce maximum noise, so maximalize fan speed. What are the common solutions for capping CPU processing power, to not let it overheat to the level which needs intense fan cooling? The Linux is an Ubuntu 22.04. The machine is a Gigabyte GA-H81N-D2H motherboard + Intel Core i3-4130 3.4GHz. The case has only the CPU fan.

I have Arch linux installed on my old Acer Travelmate 5760 and I was trying to software control the fan speed and status, but I can't find anything about the fan with lshw and lm-sensors and also the BIOS is quite old and doesn't have any fan option. I also tried NBFC and I can actually change the fan behavior but not really control or monitor its speed (there isn't the exact model configuration and with similar models the values are wrong and the effect is quite random). How the fan is actually controlled at low level? In the kernel? How can I get information on how the fan is controlled? Can I just read/write to some *file*, *register* or something similar to monitor/control it?

Background: I've been having difficulty controlling my (Ubuntu 20.04) laptop's cooling fans. When the laptop was factory new, it had an app always running which monitored temperature and gave me manual control over fan speed (with a generally-effective 'auto' setting). However, at some point, it appears that a driver or other app installation which I did has begun interfering with this and I no longer have easy control over the fan systems. Main symptoms: - Multiple fancontrol type programs exist on my computer. This might have been a byproduct of a previous, failed attempt to resolve this situation, but it's certainly exacerbating it. - How many? Not sure. So far, I've identified clevo-fancontrol, juno-fancontrol (produced by the laptop manufacturer), and fan-nvidia. - Changing fan speed with any one program causes the fan speed to increase briefly, before returning to a low setting. - All three fancontrol apps seem to be unable to detect the temperature of the GPU, listing it at 0 degrees. - This leads me to suspect that an nVidia driver is at the root of my troubles... In the interest of figuring out what is going on, **I would like to be able to monitor what signals are being sent to my fans, and what apps are sending those signals.** Is this possible?

I am running Linux Mint on a PN50 Ryzen 5 4500U. Fan is very loud and I think it can make it quieter with a little bit of fan RPM control. However, I am not able to detect the fan speed:

$ sudo pwmconfig
