I apologise for asking a question which has been answered many times.
I've recently built a new system using these parts:
Gigabyte Geforce RTX 2080 Super
AMD Ryzen 7 3700X with the delivered stock cooler
MSI MPG X570 Gaming Plus
16 GB RAM
The CPU idle temperature is about 50 °C, but it's about 40 from time to time, but mostly at ~ 50 °C. After 10 minutes of gaming, the temperature is at 90 °C, measured with MSI Afterburner.
I don't know what to do now. Is this normal or is that definitely not good? What could be the problem? Is it maybe the cooler which may not be enough?
NB: I'm very new in this subject, so please have some patience with me .
