It is okay for CPU to reach 90+ C?

In the past couple of days I monitor my CPU temperature and when it on heavy work load like redering, the CPU temp go beyond 80 or sometime even 90 degree celsius.

Is this kind of normal? or I need to change any of my hardware?

You should replace it when you start to see your average idle temperatures rising or loaded temperatures reaching close to Tjmax (~100c)

you have told us nothing.

So we can have more information about your system, Download, run, and save the results of this utility as a text file:

You didn't mentioned what CPU you are using. However, I can confirm that usually the maximum permissible CPU junction temperature is 100 C. So, 80-90 Deg C under heavy load seems to be normal.

I'm using i5-8400 for about 3 years

I have been reading about the thermalpaste, how often do I need to replace it? and will it reduce my cpu temperature? I never replace it since I got this PC.

Thanks for the helps

In 100% full load on all cores is OK , specially in a closed case. If it gets close to 99degrees you need to take measure , like 95+ degrees since it will throttle
