i9 9900k getting super hot



For the past week my i9 9900k CPU has been running at crazy temps. On idle (with no start up applications and cpu under 5% ) it hits between 50c - 60c, and under any load it easily hits 60c +. Additionally, while gaming or under a lot of load, it jumps straight to 80c - 100c (within seconds of the application opening). I don't understand why its reaching near these temps, especially because I have a NZXT M22 liquid cooler.  Furthermore, I have done almost every troubleshooting solutions under the sun. 

List of things I tried: 

- Re installed the CPU and cooler many times and made sure no plastics was on the heat sink

- Re applied thermal paste (Thermal grizzly Kryonaut) 

- Made sure that all drivers and bios was fully updated 

- Got a new fan and checked if all fans were working for good air flow (balanced air flow)

- Put bios on default, made sure the CPU is not OC, and turned vcore down

-  I made sure the radiator was oriented correctly and the pump was working


I really don't know what else to do, should I just use my warranty on my CPU? I will include my pc specs down below as well. Any advice or tips would be greatly apricated! 


PC specs: 

- CPU: Intel i9 9900k

- RAM: 2x 8 gb Corsair Vengeance

- GPU:  Radeon RX Vega 56

- Motherboard: Prime Z390-A

- CPU Cooler: NZXT M22

-  Case: Fractal Design MESHIFY C

- Fans: 3x Fractal Design fans, 1x NOCTUA NF-P12 Redux

- Power supply: EVGA SuperNOVA G5

Hello Mori1

Thank you for posting on the Intel communities. In order to have a better understanding of the issue, please share with us the following information: 

  1. Where are you looking at the temperature of the CPU?
  2. Have you gotten any BSOD or error messages?
  3. Did you overclock the processor?
  4. Did you enable Intel® XMP? If so, which frequency where you using?

Also, please download and install the Intel System Support Utility (Intel SSU): 

Open the application and select "Everything" click on "Scan" to see the system and device information. By default, Intel SSU will take you to the "Summary View". Click on the menu where it says "Summary" to change to "Detailed View".  

Click on "Next", save the report and attach it to your response.
