Warranty on unscrewing Cooler?

Hello,

so i wanted to put thermal pads on my new MACBOOK AIR 2020 (Quadcore),

as known the quadcore gets to 100°C really fast, i cant even use Chrome without having the fan sounding like a plane. So my main question is, if i lose warranty if i unscrew the cooler to put thermal pads between the cpu and the cooler, (apperently the cooler doesnt have direct contact). i know that i wont lose warranty when unscrewing the backplate, but i want to make sure i keep the warranty, since my macbook is 3 weeks old.

Thanks
