Laptop overheating after replacement thermal paste

[Veyron7887]

Hi. I have Asus X55C laptop from year 2013. It has i3-2328M CPU. I replaced stock thermal paste with high quality thermal paste. Before thermal paste replacement, I measured CPU temperature Around 65-70 degrees Celcius with stock thermal paste. If after the replace thermal paste, I measured CPU temperature around 80-84 degrees Celcius and fan don't stop when system is idle. I replaced the thermal paste several times but still did not change. Where is the problem?

Is the heatsink on top of the CPU properly to dissipate the heat generated by the CPU?

Does the logic board power up ok - other than this heating issue? Inspect all sides of the CPU to be sure the metal is touching the top layers of your heatsink compound.
