    Good to know, always thought the limit was made up by the chip manufacture. But if I recall correctly iunlock mentioned that his FET got up to 105°C before throttling.

    I think this cpu thermal limits 97 not 105

    Do what I do, stop giving a toss and leave it alone after a repaste and enabling speed shift

    I don't know about XPS. But it's unlikely you will find temp sensors for other than cpu, gpu, pch and ssd's in most laptops. Some even with no temp reading for pch and ssd's. It's the ODM/OEMs who put the limits in their cancer firmware!!!

    FYI T junction temp is 100C for newer Intel processors.

    For power limit throttling, the limit is a bit over 70 at the sensor in the VRM area. That 105 was measured manually on a mosfet.

    I have vacation right now and might test the mod with the heatsinks and the modded ventilation, iunlock published.
    But you´ve got a point there.
    I do have to manually enable speed shift? Thought MS did implement it in Win10 last December and it would be enabled by default.

    I just reread iunlocks post and he had 105°C on the first ambient sensor (HWiNFO64), which should be near a mosfet.
    Did I get it wrong? I thought when this sensor reachs 105°C the CPU or GPU would throttle, because the mosfets are too hot?

    Thank you guys, learning lots here.

    This laptop by default has speedshift disabled and all option hidden, you can either use throttlestop at startup to enable it or as I have done via the EFIshell to flick the switch in the BIOS, then I added the reg entries to show the options needed in the power options, it's all in the 1st post here.

    If you enable speedshift and change nothing turbo is technically disabled as it never reaches it, I changed "Processor energy performance preference policy" to 40 so the max turbo multiplier is reached.

    There is a full thread here dedicated to SpeedShift on the XPS which will get you started. I think SpeedShift is an excellent Intel feature for energy savings and can provide some performance enhancements for laptops

    hahaha. Unfortunately with the XPS, if we disable c-states, we lose turbo speeds.

    SpeedShift is snappier than SpeedStep (or disabling c-states) so you can have your cake and eat it too!

    @GoNz0 , @pressing Thanks guys, I´ll enable speed shift as soon as I get the XPS.
    Really thought something like that would be enabled on default, cause it´s an advertised feature of Skylake, what was I thinking :)
