Are you sure it going off? What "cat /proc/acpi/bbswitch" and "optirun --status" do say? Anyway I can't say sure for i7 model. > I am not convinced the fan issue even has anything to do with the graphics. It has to do with termperature. And running nvidia always on (default behaviour) leads to higher temps and so spinning fans. > Stay far away from it if you are a Linux user > From mine point of view, buying this model was a big mistake for Linux usage People, let's don't extrapolate your negative expirence with 7559 i7 model on 7559 at whole or 7566 (which is not even tested). As for me 7559 i5 is a very good model for Linux. Even bad Skylake support under Linux shouldn't short CPU life, since this model uses HQ series processors, and not U series. -- 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: Triaged 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.
