NkM1337 you need to get it properly repasted with kryonaut or similar the thermal paste you used its rubbish use the spread methos only a thin layer covering both diodes its enough too much its bad same as too less also optimize your windows properly and undervolt with TS also make sure the fasn and exit airflow are properly cleaned and lift the back 2/3" for a proper airflow good luck

Hi @NkM1337,

Try undervolting with Intel XTU and if your max temps go above 90 then you need to get thermal paste repasted from Acer Service Centers. Also if you have 8th gen CPU, you can try turning off two cores using Intel XTU.
