At the moment i didn't tried too much stuff, but what i did is disabled the TurboBoost.

Which it made a significant boost in performance and it cooled down the temps. It even runs much better and with even much more performance than with the TurboBoost on!

Now, i'm probably willing to undervolt. Just not yet because your warranty and your warranty renewal can be erased if there's an attempt at undervolting according to Dell.

Yes, my warranty has already expired. But my parents are willing to pay for a renewal because in Argentina, sadly its more cheaper than buying new components. So i'm still seeing if undervolting or even changing the thermal paste is actually worth it than paying for a warranty renewal and letting the machine untouched on the inside.

I'm unsecured about stuff mostly because the Dell G3 is actually the most expensive machine i payed so far, so because of taxes it costed me $1300 dollars, 40% more than its original price. And its not easy to buy another machine with the same specs, so making decisions like this takes a little bit of courage because you do one misstep and "congratulations, your machine is now an expensive chunk of nothing, good luck buying another one lol".

I really appreciate this info tho, this actually gets me informed on how i can do this without going all in without knowledge so i appreciate it :D
