Could you anybody please test and confirm whether this setup with 6700HQ
- BIOS 1.2.0
- Kernel 4.8.11-040811-generic
- installed nvidia binary driver 375.20 - switched to intel gpu using prime
- boot with additional grub parameter acpi_osi="!Windows 2015"
(yes use doubleqoutes)
I do not want to make premature conclusions, but so far it seems that CPU
temperatures on idle are about 40C and fans seems working correctly (they are
switching off), at least I am noticing correct fans behavior for the last 2
btw I am running my laptop on Mint 18 Sarah

Dell Inspiron 7559 fans do not shut off once started, even when cool
Status in linux package in Ubuntu:
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
Below is the output of lm-sensors showing the fans running when the
CPU is at a cool 35c
