Inspiron 7559 with i7 Linux fan control problem

Hello.

I have Dell Inspiron 7559 with i7 cpu. I've noticed problems with fan control on Linux (I've tried many distros and kernels from 4.4 to 4.6.2, run it on nvidia or intel gpu only, but the problem is the same). Once the fans are started to spin, they are spinning forever even when the system is cooled down (cpu and GPU has about +30C for more than hour). On the same machine on Windows 10, fans are switched off when the system is cooled down. I've tried to config it using pwmconfig which could stop and speed up the fans during the configuration, but after saving config to /etc/fancontrol it did not help at all and fans are still spinning. I've found that setting acpi_osi=(Windows||Linux||!Wiindows 2012) on grub might help, but after various attempts and settings it did not help at all. Could you please anybody help me to configure this fancontrol or help me to setup it with behavior as like as on Windows 10 is or make a patch for kernel/driver or whatever... I need Linux (not in VM) for my work and it is really disturbing once the fans are started to spin even at the speed at 2k rpm and I need to be focused on my work. Thank you.
