CPU Overheating? Need Assistance :(

[Calv7]

I've just built myself a new gaming PC annnd yes it is my first time. These are my specs.

 

Case: MSI MAG 010 Vampiric 
MB: Aorus B450 Elite (AM4)
Thermpaste: Arctic MX-4  
PSU: Corsair VS550W 80Plus
RAM: Corsair Vengeance 32GB DDR4-3600MHz 
CPU: AMD Ryzen 5 3600 
CPU Cooler: AMD Stealth (stock)
GPU: Gigabyte Radeon RX 5700XT OC

 

My CPU is heating to about 92-100 degrees when I run IntelBurnTest on High. I'm not sure if this is normal as I am using the stock cooler or I did something really wrong. My idle temps sit around 42-45 degrees. I haven't tested any games as I wanted to ensure my system was stable before doing anything significant. 

 

At the moment I have 2 intake fans at the front and 1 extraction at the back. I plan on mounting an extraction fan at the top to improve airflow. 

 

I have tried: 

- Repasting the CPU by removing the stock thermal paste = 2 - 3 degrees improvement.

- I then repasted as I was unsure if I did it correctly = no improvement (put a small amount in the middle)

- Reinstalling the cooler = no improvement

 

I would really appreciate some advice. I thought the stock cooler would do just fine as I never planned to overclock the system. 

 

P.s I haven't overclocked.

"put a small amount in the middle"

 

This is your issue - put a cross pattern and make sure the mount is good. Also, is PBO enabled? Sounds like the typical Gigabyte board issue where it overvolts the CPU

Thanks for replying.

 

I put more paste in a cross pattern and it still spikes the temps. I disabled PBO.
