The voltage on the processor jumps, how to deal with it?

Question

Iron

I bought an Acer Nitro 5 laptop half a year ago, a link to the specifications! I bought a ssd samsung evo and replaced 1 bar 4GB with 16GB hyperx, as a result, 20GB of RAM now.
When I bought a laptop, I didn’t notice drawdowns in the processor frequency, it also warmed up in games up to 90-93 degrees, but I kept my 4GHz in turbo boost and the voltage was 1.2-1.3v, but for the last 2-3 months I began to notice friezes and a drop in fps in games, I noticed that the frequency of the processor in games has become 2.7-3 GHz, the voltage naturally dropped less than 1v. at the same 90-93 degrees! What could be the problem?

Z.Y. I changed the thermal paste a month ago, bought a stand for a laptop (6 coolers, 3 of which blow directly into the laptop's air intake grille), but I didn't notice any changes, still the same drawdown in frequencies and voltage!

Answer 1

blowing directly into the laptop air intake grille

Here it is. If hot air comes out of this grate, then you drive it back.
And the voltage drops due to throttling so that the processor does not burn out. Solve cooling problems and everything will be ok.

Answer 2

Do not forget that under overclocking, the degradation of semiconductors accelerates

Answer 3

Maybe the problem is that the installed RAM is worse in timing, it heats up more against the general background, and the process suffers from this.
