Intel i7-8750H extreme heat

Hello!, I use a Dell G7 7588 laptop with an i7-8750H and a GTX 1060 Max-Q that I got back in 2018. Recently when I play games I notice a great decline in the processor's clock rate where it freezes at 800Mhz and like 10Watts TDP making any game unplayable. Additionally, When I run the TS Bench or Cinebench R20 the TDP rises to like 70 Watts and then it throttles at 2900Mhz and 44.5 ~ 45W TDP and limits windows show PL1 and EDP Other in constant red color. Of course, thermals are a major problem for me so I undervolted both the cache and the core to a -125mV but it didn't help much with either the throttling or the thermals. For the record I use ASUS GPU Tweak software because for some reason the GPU thermal throttles at 77 Celsius which didn't happen before. I tried to increase the Turbo Boost Long Power Max to 55 but it didn't work. Is there any solution for this?.

PS: The CPU ran fairly and didn't throttle when I shut down the ASUS GPU Tweak software. But, now I get 99 Celsius constantly on games like No Man's Sky and Remnant: From The Ashes. Also the throttling is still there when using CinebenchR20. Tried to disable the Turbo Boost but the temps are still about 85 ~ 90 and the GPU is like 90 ~ 95. Any solutions?

Well if you aren't afraid of breaking your laptop then I suggest repaste the CPU with better TIM. Recently I repasted my Triton 500 laptop with 10875H CPU with Thermalright TF-X and it has been very good.
The Thermalright TF-X is best suited for Laptop because it has very high viscosity --> less chance of TIM dripping out when you put the laptop in backpack in the vertical position.

Unfortunately, I am afraid since I do not have much experience with laptop hardware and truthfully I don't trust anyone in my country to do it for me. I noticed that the laptop throttles even in the lightest of games like Valorant and with Turbo boost disabled. I can play it smoothly for like an hour or so and then get thermal throttling on both GPU and CPU which is really frustrating. Is there any other solution?.

Try setting Turbo Ratio Limits to 39 all cores, and decreasing (higher negative offset) Voltage offset for the CPU Core to around -250 and leave Cache as -125

If I remember correctly the CPU/GPU of Dell G7 15 is soldered to heatpipe, no repaste possible(or necessary), assuming that you are outside warantty period, the only course of action is to use a external laptop cooler, and to clean your vent.

WUT no!
The heatpipes and cooling block unscrews from the Motherboard.
