    Who did you talk to about the temperature? 95c is their threshold for taking action. They won’t send a tech out for anything under 95 but anything over 95 definitely is an issue.

    This leads to one more question , Is GSync important or useful in a Laptop with GTX1070 and 120Hz monitor? Like the AW17.

    That’s up to you. Many of us went with the gsync model for its benefits over the cons but not everybody wants that.

    I recently noticed that my FPS was kind of low-ish so checked and it was running at 1750MHz under full load, 80C, so I ran Afterburner, lifted the curve a bit (undervolted) and now it is running at 1850MHz-1950MHz and I got my FPS back. Obviously the thermal paste (MX-4) is deteriorating and it's been less than 2 months since repasting !

    right I have just downloaded XTU and Throttlestop.. no I know I need to undervolt the i9 to try help with temps.. how do I go about doing this? (im used to desktops and doing it all in the bios :D)

    Anything else other than doing the repaste I can also do to help?

    even at idle the laptop is running at 4.3ghz

    In XTU go to "Core" on the left, bring the frequencies of active cores down to 4.3GHz all locked, above that it says "Core Voltage Offset" set it to -100mV. I do not use TS because its user interface is ridiculously bad. I would also advise getting MSI Afterburner, and even though its user interface is on a par to TS for stupidity, yet, you can lower the voltage of your GTX 1080 and achieve better frequencies and frame rates of course.

    The i9-8950HK + GTX 1080 combination gets exceedingly hot. The GTX 1080 generates 180W of heat. The i9's cooling system is very fragile as is, let alone with 180W of heat right next to it. On the other hand the i9 at 2.9GHz (its base frequency) and six hyper threaded cores is a very powerful CPU as is. I am not sure what end-user application would benefit immensely from going over 2.9GHz, and more importantly when this application is running do you also need the GTX 1080 at 180W ? Most games I have played do heavy use of the GPU > 95% but relatively little of the CPU < 30%. As a result I would clock down the i9 to something like 2.9GHz - 3.6GHz and be happy.

    That is after you re-paste both CPU and GPU with very good quality thermal grease. I have also found that the two fans' air intake grills get exceedingly blocked with dust that must be cleaned out regularly. Laptop standing on a raised base of course.

    The 1080 never goes above 75 though I don't know what the thermal limit is on that The cpu I used xtu and stuck it down to 4ghz and -050mv. Im guessing I can probably go lower then?

    Here’s a better photo of what I’m experiencing. I just want to know of other people with the TN panel have these sort of dark areas and if this is typical or if I should be getting another panel.

    side note:

    the 1080 get's only hot when you run it stock. a 1080 undervolted to 0.875/0.900 Mv on 17/1800 Mhz will yield around 130 watts without sacrifing performance. The Pascal series is a very streamlined architecture which does not need high voltage for it's boost clocks (can boost clock without crossing 1V and without having to won the silicon lottery). i can use my 1080 stock, but i rather shave off 30/40C off the GPU to run my cpu full speed. I can now for example my gpu with a max of 140 Watts and my CPU locked to 65 watts. (long powerlimit, short is still 110) now my GPU and CPU run full speed all the time (but i let it downclock cause just like you said a 6 core cpu on 2.9 Ghz is already fast)

    And what you use the tools user interface for? As Wallpaper? Fancy multi colored graphs doesn’t do a ****y outside eating clock cycles.
