@peter-biely, I'll recheck during this weekend. In the meantime, as I previously indicated, I tried 16.10, and unfortunately: problem persists. fans keep spinning even when idle.
I have also tried i8kutils while on 16.10, and find that it works fine. - turns off fans properly according to config threshholds - turns on proper fan speed according to proper threshhold - when daemon is turned off at idle, BIOS automatically kicks in and runs the fans and I've also tried i8kutils on my working system (16.04) and it works alright - the difference I notice is that BIOS doesn't seem to automatically turn on fans when I turn off i8kmon ( unlike in 16.10 ), however I tested the BIOS' ability to run the fans by running a heavy task and it does start the fans at some point * this is the only observeable difference I see between i8kutils on 16.10 vs 16.04 as observed in other posts, despite this solution via i8kutils, windows is still able to better optimize idle state on skylake. in the meantime, i8kutils is nice to have, battery improved from ~3.5 to ~3.75 on my typical load: 2 ides, 1 container + additional services. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1602888 Title: Dell Inspiron 7559 fans do not shut off once started, even when cool Status in linux package in Ubuntu: Incomplete Bug description: Running Ubuntu 16.04 on a Dell Inspiron 7559 laptop there appears to be an issue with the fan control. When I first boot up the machine the fans are off. However, after the laptop warms up under normal usage, the fans kick on and then never shut off again. Even when the CPU cools down to below 35c, the fans will continue to run. If I suspend the the laptop, and then immediately wake it up again then fans are once again off, until it warms up again. So essentially, once the fans start they don't seem to ever shut off. Fans seem to work normally under Windows 10. They turn on as needed, and then turn off once the laptop cools down. I've tried the various BIOS updates that Dell has released, without success. I am currently running Dell's latest BIOS for this laptop (v1.1.8) Below is the output of lm-sensors showing the fans running when the CPU is at a cool 35c dell_smm-virtual-0 Adapter: Virtual device Processor Fan: 1925 RPM Processor Fan: 2143 RPM CPU: +35.0°C GPU: +1.0°C SODIMM: +49.0°C ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.4.0-28-generic 4.4.0-28.47 ProcVersionSignature: Ubuntu 4.4.0-28.47-generic 4.4.13 Uname: Linux 4.4.0-28-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: bob 1709 F.... pulseaudio CurrentDesktop: Unity Date: Wed Jul 13 19:18:45 2016 HibernationDevice: RESUME=UUID=14de580b-76f3-47e4-9850-fe7637f9ff77 InstallationDate: Installed on 2016-07-13 (0 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) MachineType: Dell Inc.
