Overheating CPU TUF F15 2022

[OndroT25]

Hello, I'm using Asus TUF F15 2022 FX517ZC with i5-12450H, RTX 3050 4GB, 16GB DDR5 RAM. The laptop has been serviced twice and the motherboard has been changed. My problem is that the CPU temperatures are around 85°C at 20% CPU usage. The fans are running at maximum. Compared to before the service, I played Tomb Raider (2013) on normal details and the CPU temperature was around 65-70 °C. Now, when I play with low details, the temperature is up to 85 °C and higher. GPU temperature is normal, fans are running properly.

I ran the Asus diagnostic software and no problem was found. So if there is anything I could do/test to find the problem? Or is the most likely problem with the cooling system (thermal paste missing, CPU is badly connected to the cooling system...), so I need to send the laptop to a workshop for checking.

Thank you in advance for any help.

if you have bios version 305, you could try undervolt, which lowers the temperature by 10 degrees, bringing it back to safe temperature. It is a safe procedure that has no contraindications except for a possible blue screen.
Then you can figure out if it depends on improper fan mounting or thermal paste or some other reason.
