Following to this there was a conversation on #nouveau:

Reverting a part of the above noted patch:

-    /* starting from fermi, fan management is always linear */
-    if (nv_device(bios)->card_type >= NV_C0 &&
-        fan->fan_mode == NVBIOS_THERM_FAN_OTHER) {
-        fan->fan_mode = NVBIOS_THERM_FAN_LINEAR;
-    }

hides the bug away again.
