dmesg kernel 4.4

On my machine with an:

  Model: "nVidia Quadro FX 1500"
  Vendor: pci 0x10de "nVidia Corporation"
  Device: pci 0x029e "Quadro FX 1500"
  SubVendor: pci 0x10de "nVidia Corporation"
  SubDevice: pci 0x032c 
  Revision: 0xa1
  Driver: "nouveau"
  Driver Modules: "drm"

graphics card, the gpu fan start running at high load.
The issue started after installing openSUSE Leap15 with kernel version 4.12.
The same issue is visible using kernel version 4.17.
It was working fine on older openSUSE versions, up to kernel version 4.4.
Installing kernel version 4.4 on Leap 15 makes the issue go away.
The nouveau driver debug logs show when booting with kernel 4.12:
