    Despite having the Unlocked BIOS for AW17 since a couple of weeks I couldn't test it myself due to the work and new place... :(

    Edit -
    @Striker1234 were you able to set custom Fan tables, like raidriar ?
    Striker was also not able to set the GPU fan but in his case It's a Zotac GTX 1070..

    What exactly are u changing?
    For fan control I believe you should go to Advanced-> Platform Thermal Configuration. Against Active Trip Point 0 & 1 Fan speed you can find [100] & [75] and as far as I understood it means % of max fan rpm, not the temperature.
    Active Trip point 1 you can change temp fm <55°C> default to lower one.
    If you disable automatic thermal reporting you will have access to Active trip point 0 as well.
    Passive TC1,TC2 & TSP are used in formula defined by ACPI. In other words when OS will start throttling of cpu. 1, 5 are running numbers of pre-determined temps, looks like 1=disabled, 5= 39C. But I totally switched off Passive cooling policy as it starts throttling of cpu to cool it down. Active policy is using cooling fans instead.

    There is one tricky point here - what device is used for cpu temp monitoring, as there are at least 3 different sensors. Setting for one may override or not override settings for others..
    I think if you make adjustments in Platform Thermal Configuration then you should disable DPTF for example...

    I can only perform test of 10 minutes, and no success, since the 1070 start getting hot I have to turn off the PC and continue playing with DPTF.

    :(

    But what @AlexG73SW said about the diferent sensors makes me sense!

    I have tested it all, DPTF does not work with my CPU. Maybe this is an issue with my machine so I would be really appreciated if someone with non MX cpu could test DPTF/Thermal Configuration.

    IF intel's dptf driver installed in windows, did you try to change relative settings from window's power settings?

    DPTF driver on DELL webpage is only for extreme cpu, so that would explain why DPTF in unlocked BIOS does not work in my scenario with i7-4800MQ
