1. Buy thermal paste (grey is better), 30-50 pesos lang good for one use.
2. Phillips screw drivers (150 pesos ang set, bili ka sa cd-r king)
3. Search google/youtube on how to open your laptop
4. Pray to the Lord and ask for courage and wisdom before performing any task. (you need it)
5. Presence of mind regarding the parts you are about to tackle.
6. Remove and clean the fan and air inlet/outlet, Im sure some dirts are blocking the airflow that prevents good ventilation.
7. Remove the heatsink (copper metal) attached from your gpu and cpu.
8. Rewatch youtube on how to clean them (and ofcourse follow instructions) and then apply thermal paste.
9. Re attach everything.
