Blade 15 (8750H) Are these CPU temperatures normal?

    As of the past several weeks my Blade 15 has been seemingly running hotter and hotter, currently with a -130mV undervolt I am getting idle temps of 56-65C with an ambient temperature of 23C and fans always plenty audible. When gaming, most cores get up to 95 and one core frequently hits 100C.

    After dusting out the insides and locking the CPU speeds to <1000mhz, i'm still getting idle temps of ~54C.

    Are these temps normal? and if not, is it something redoing the thermal paste with something like kryonaut or MX4 can possibly fix?

    Strange, I noticed the exact same thing and I'm about to return it to Amazon - do you think we have burnt out our machines? I've had mine just over a year and it's on every day for work and Battlefield V @ Ultra settings very often. I can't get this thing to cool down whatsoever while gaming, I have the same undervolt applied as you and it's touching 90 degress with turbo disabled (2.2ghz!?) It often spins up to 75 degrees just opening FireFox!?

    Also worth noting my idles are 51 degrees also, the highest I've ever seen in a laptop to be quite honest. Following this thread - let me know if you find any kind of "fix" before I pull the trigger and return this thing.

    Since kabylake 50ish degrees HQ/H cpu on idle is normal, may spiking to 60ish because the frequency spike also to 3,9 on my case on Blade 15 2018 early batch with black vapor Chamber. On control in 2 hours gaming cpu spiked to mid 90ish but it’s normal activity if I don’t limit the clock amplifier, the most important is average gaming temperature which’s still on mid 80ish on cpu and gpu high 70ish. My profil is default (no bios moding to remove power limit) balance lock to 25Watt. Control runs well on 1440p with that 1070maxq around 50ish FPS no huge Frame drops like to 30.

    For a laptop that runs so hot at idle I think the GPU throttle temps are pretty low, it seems to kick in around 80 degrees which isn't too hard to hit ... a 90w PL is a joke seeing as you can't even touch it with these thermals.

    What? For 1070maxq 90 watt is already great some are like gs65 Aero 15 even use 80watt, do you want more? probably vrm won’t be able to supply the power demand. GPU fans kick in more often the cpu since it’s the main heat on a laptop, in my case I can play even on its keyboard on last summer it’s warm but not too hot to touch.

    I'm saying the chassis is getting so hot that 90watts is impossible to touch.

    90 watt doesn’t translate 90 Celsius, but yes higher gpu tdp may cause higher system temperature since gpu is main heat on most laptops. However I use mostly balanced mode that limit cpu tdp and (on some 15 model) limit the gpu tdp to 80watt, and use high fans rpm to be able playing on its keyboard.

    SO weird how this differ. In the Blade 2019, the performance mode doesnt do anything. In btoh cses the CPU is maxing out at 45watt TDP.

    GPU performance mode heats up the system a solid5c. but Firestrike scores remain the same. So I am just running in normal mode. 6 core clocks speeds limited at 3400mhz with a 135mv undervolt.

    Yes there’s several differences, like 15 2018 on gaming mode it’ll OC the gpu on core by 100 and memory 300, no matter dgpu 1070maxq or egpu 2080, the same OC values would be applied on gpu on this mode, about tdp on gpu there’s no chance both mode balanced and gaming use 90 watt unlike mid 2019 15 i believe, only cpu that lock on 25 watt on balanced and gaming (depends on Bios Version, some 45 and some 35 watt).
