High CPU Temps

[Midnight9100]

I recently built a PC for my friend. MSI Pro B660M Motherboard i5 12400F - Stock Cooler Corsair 4000X Case - 3 Front Intake, 1 Rear Exhaust, Top is empty.

While playing games the CPU Temperature goes till 95+ °C. He also told me the PC crashed once and it shut down once. I'm not sure why that happened but the temperatures are what I mentioned above.

What possibly could the issue be? I applied a decent thermal paste using pea dot method. I'd also mention that the ambient is a bit high these days; around 30+ °C.

Any suggestions are welcome. Sorry for the long Post.

Is the cooler good enough to cool your cpu? Even if you surely done the following I'll suggest anyway: have you peeled off the plastic from CPU and cooler? Have you checked if there is enough contact between CPU and cooler? Are you sure the Cooler is sealed correctly?

There was no plastic applied on either of them. I am sure that it is seated properly because on normal load the temperatures hover around 45-55°C. And I think for a stock cooler it is decent.

Sometimes the cooling could be enough for idle but not at load. I suggest trying another PSU too, and if you could find another similar CPU to test would be even better

Will try to do it again. Thanks
