Question CPU Throttling when gaming

[KaspaStul]

Hello, I have a very annoying problem and can't figure out what's wrong. I've gathered some information and stats in hope that it'd help.

For quite some time I was having a problem with throttling of some kind. After playing some games for an ~hour, it begins to drop frames every few seconds, after 5 seconds of dropped frames it goes back to normal for ~15 seconds and then drops again.

I've updated my graphics drivers, BIOS, installed a fresh Windows, closed everything except the game, used "game booster", disabled windows virus protection, cleaned inside my laptop, made sure that power plan is on "High performance".

I bought this computer 3-4 years ago for on-the-go video editing and casual gaming.
2 years ago I remember bragging to my friend that I can run GTA V on high settings and get stable 60fps. Not anymore.

Installed Forza Horizon 3 a few days ago. Quite unplayable. Everything turned to lowest still getting 30-40fps and everything seem unusually choppy (not like "30fps choppy", worse) and delayed all the time.
Installed Apex Legends. On lowest possible settings I'm getting 25-35fps.

Troubleshooted everything and found out that my cpu maxed out on 100 C sometimes. Cleaned and changed thermal paste, temperatures now maxes at around 85-97 C. It is still too high I believe.

Specs:
CPU: i7 6700HQ 2.60GHz
Ram: 16GB 1063MHz
GPU: 4GB Nvidia Geforce GTX 960M
Windows 10 Pro
(Lenovo Y700)

I'm lost 🙁

Launch HWMonitor, and then run the game; if it does not hit the throttle temp, you might have solved it with new paste application. (Laptops are difficult to cool when gaming, historically; in my opinion, most are not properly cooled to handle a steady gaming load.

Yeah, I've found out that laptops aren't that good for gaming, but the thing is that previously it worked just fine.
