Hi, I just built a new rig with following parts:

https://pcpartpicker.com/list/WxKZ8Y

After done setting up i tried to OC my core to 5ghz, according to this guy https://youtu.be/CoUtA7DKXhU

unfortunately once I started stress test on CPU it just get heat up super fast nearing to 100C and auto shut down in any of benchmarking tests

I tried stressing again after changing the thermal paste on cpu to kryonaut (was stock thermal paste from NZXT) and still overheat.

Hence, I tried to tune down the overclock by setting CPU Core Ratio to 48, making it achieving only 4.8ghz

Tried on stress tests again (CPU-Z, XTU, 3D Mark, Cinebench) This time all passed without auto shutdown but the temperature still hits over 90 once awhile, which i think it is still unhealthy?

So, is the only option is delidding? or there might be any setup problem?
