Problem with my Razer Blade 15 (2018) I7-8750H with GTX1070

Sorry to hear that, battery bloating common reason is heat, yes as you thought it’s thermally throttling, and system sometime protect its self by shutting down it, that’s called overheating. First you should periodically clean fans areas, Blade 15 intake air that might mix with dust around bottom areas the Fans radiator would be easily dusted and slow down the fans to cool system. Second in like 2 years or maybe less if you see high temperature even you use cooling pad or cleaning fans that might mean that cpu or gpu thermal paste isn’t rightly applied or drying out in this case you should repasting it. 3rd nowaday title stress more cpu than before due more rendering process on some scenes, with cpu boosting on max/high frequency for long time it might spike the temperature near its limit, this’s not only on Blade laptops, other brands especially on this thin light categories suffering similar issue, users limiting max boost clock to lower frequency using 3rd party apps like throttlestop and Undervolting it to low the temperature, some (including me) even disabling the Turbo Boost on some titles to avoid 90degrees temperature, especially when playing long session. Tldr heat is Laptop big enemy so try to lower it at any cost like a bit lower FPS is important imo, and your 1070maxq even by disabling it still can run anything at 1080p fine (I know since I’ve also same blade model). Hope that help

Thanks for your help, when the laptop guarantee expired I repasted it with thermal grizzly and cleaned the dust, I am also using throttlestop for undervolting the cpu and turned off the Turbo boost but didn't help. I will give a try for a new paste after this 8 months maybe i should try the liquid metal. I think that's my last chance.

Kryonaut? That one according some users fast dried out again and need repasting again, ic diamond or mx4 maybe worth a try, I use later with minimum improvement ended up by disabling Turbo Boost since it doesn’t take huge impact on my use case, and cool the blade like a lot. No I don’t see good results on LM on Blade 15 vapor chamber, I think it’s because mix cooper nickel, not sure and clean it if something goes wrong might be difficult.

I will give a try for the mx4 thank you for your advice.
