u/Legitimate-Fan-6742

My cpu 102 deg plus lenovo changed heat sink issue came back reapplied thermal paste and cleaned fans still issue comes back
Got the laptop in 2022 after 5 months overheating
Than I raised complaint
Lenovo took more than a year to fix my issue and replaced heatsink finally
After that the problem came in 1 year again and I got the laptop fans cleaned and thermal reapplied and it worked fine for a year now when I did the thermal paste reapplication and fans cleaned the issue still persists

Can anyone please help me
Is this a manufacturing fault maybe ?
