Was suffering from a heating issue on my device with cpu temperature averaging 99-101. Opened the back panel removed the fans cleaned everything nothing worked.
What worked- went to nehru place and found a shop ( gs infotech) on reddit initially also got recommended shree laptop solutions but they were offering cleaning and liquid metal change on cpu + thermal paste change on gpu for 1500 while gs infotech offered that for 1000. Went with gs infotech and realised that without proper tools I wasn't cleaning my fans properly there was a lot of dust and also the liquid metal needed reapplication.
Result- temperature brought down from 99 to 79 which was the average temperature when I originally bought the device finally this despair of 1.5 yrs ended.
Fyi- the temperature was fine till 1.5 yrs (i bought the device in 2023) after that it saw a sharp increase
Model- PHN16-71
Once again if anyone is also worried about killing their device go with one of the two shops mentioned they have exceptional reviews on reddit and my experience with gs infotech was also amazing.
