This issue was solved with update 1.20 of BIOS. Apparently it was a known issue (raised on Lenovo forum) that could occur with some combination of settings, etc.

I have a Dell XPS 13 (2013 edition, the 2015+ edition may be different). The fan is primarily controlled by BIOS. It appears invisible to almost any Ubuntu software. It responds to i8kutils commands, e.g. i8kfan 2 2 makes it run fast, but after a few seconds any i8kutils commends apparently get overwritten by BIOS (I have BIOS version A08 rev 0.1 according ...

The HP 15T Touchsmart notebook with an AMD processor uses the AMD A76 chipset and it does not appearlm-sensors supports this. Your fan speed is controlled by your UEFI BIOS. You can set the fan to be permanently on within the BIOS. This option is within system configuration options. It will be worth installing tlp or laptop-mode-tools to reduce your power ...

determine which process is using your cpu by running top or ps aux in your terminal(ctrl+alt+t) post output here or try killing the process by running "kill PID" in the terminal. PID is the second column in "ps aux" first column in "top"

I have managed to fix it with the following script: #!/bin/bash sudo aticonfig --pplib-cmd "set fanspeed 0 20"

Just for the record, since I have no interest in using the intel gpu, I never have. As an experiment, I used the nvidia gui to change to intel, logged out, and, after login the same fan issue occurred in 15.10, uname -a Linux deblap2 4.2.0-36-generic #41-Ubuntu SMP Mon Apr 18 15:49:10 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux thus, as far as I can tell, ...

this may work ... you could try to edit your /etc/fancontrol file changing all the values for the specific pwm MINSTART, MINSTOP, MINPWM to all the same values .. that should make it a set speed. You may have to change MAXTEMP to a very high value so it doesn't try to spin up higher then the min values. you will probably have to restart it for the changes ...

You have two temperature sensors with temperatures of 53 Celsius and 20.9 Celsius, plus sensors-detect found something at i2c address 0X28 but could not work out what it was. Does your BIOS support fan control? Using this is going to be the easiest option?

I had the same issue on my Lenovo. I upgraded my bios and now everything works fine. You have to execute the upgrade program in Windows and then it will restart your computer and updates the bios fully automaticly

Please try opening your terminal (Ctrl+Alt+T), then paste the following: sudo nano /etc/modprobe.d/blacklist.conf and enter your superuser password. In the opened file, copy and paste (Ctrl+Shift+V) the following lines beneath the first comment, for simplicity: blacklist dw_dmac blacklist dw_dmac_core Then save this file again (Ctrl+Shift+O) and close it ...

So, I tried the drivers, and it said that my os is not compatible. I found that indicator-cpufreq helps, it looks like my cpu governor was set to performance, I can manually set the frequency and the laptop runs much quieter!

Installing the latest nvidia drivers and restarting made it work in the end. I also removed acpi=off from my boot parameters.

The Asus am1m-a motherboard is really unusual in that it does not have a CPU, a GPU and a supporting chipset, but relies on a complete system being integrated into an APU (a system on a chip). Given this unusual architecture it is not surprising sensors struggles. I suspect its going to be very hard to get sensors to work properly. I would remove lm-sensors ...

The fan is running because the GPU, not the CPU, is getting hot. You have hybrid Intel/Nvidia graphics hardware and I think the Intel GPU is getting hot because of a kernel bug. Please raise a bug report by typing ubuntu-bug in a terminal.

The MSI Megabook vr201x BIOS does not offer fan control. The vr201x uses the Intel HM76 express chipset. The Intel datasheet for this chipset states that the mobile version of this chipset does not support PWM fan control. I am afraid you don’t have the necessary hardware.

totem-video-thumbnailer creates thumbnails for videos. One possible reason it can take up lots of CPU, is if you have your file manager pointed to a folder that's used to download many media files, such as with a bit torrent client. Because then totem-video-thumbnailer will keep trying to create a new thumbnail every time the file is changed, which will fail ...

The Asus Z87-A has a Nuvoton NCT6791D SuperIO chip to read temperatures and fan speeds and control the fans. Instructions on how to read and control the fan speeds are given here fan configuration of Z97-E under OpenSUSE. They are for OpenSUSE and the Z97-E motherboard but the process will be pretty much identical for the Z97-A under Ubuntu.

This laptop comes with a Windows program called Health Monitor. When this runs it shows the CPU and GPU temperatures and the fan speed. Clearly the sensors are there, however sensors-detect can't find them. If you are comfortable with compiling and making programs you could try the toshiba utilities here Toshiba Linux Utilities However as I do not have a ...
