[SOLVED] i9 10900K running hot on a new PC(?)

[Hannes084]

Hi all!

I recently purchased a new PC, and I've had some issues with it (mainly being slow, some settings disappearing or below average benchmark results). I re-installed Windows 10 Pro, and updated BIOS. The CPU is running really hot, and I'm not quite sure why. The idle temps can go from 21C to 55C in half a second, altho usually they sit at around 35-40C.
While running benchmarks, the highest I've seen them go is 78C where it stays. After re-installing Windows and updating BIOS I've not played any games, as I'm afraid I'll fry the CPU. I've disable CME from BIOS but this had zero effect on the temps.
Overall temps are great for my 3090 and AIO cooler is always running at 100%. CPU gives 92% performance via "Performance Test" by PassMark. Are these temps normal, or too high? If they're too high, what can I do? I barely know how to tweak BIOS, but if there's something I need to check pls let me know. Thank you!

My setup is as follows:

Fractal Design Define R6 USB-C
ASus GeForce RTX 3090 ROG Strix OC
i9 10900K
ROG Strix Z490-E Gaming
SilverSTone 1500W Strider Gold S
Seagate 2TB HDD
Kingston 1TB A2000 Nve
Corsair 32GB 3600MHz
Asus ROG Strix OC 360 RGB White Edition

Image shows temps below, while running PassMark

Thank you everyone for the welcomes and advice! 😊😊😊 I feel a lot better now that I know the CPU is working just fine. Next step is to get a 4k monitor to harness the power of this rig properly 💪

Although "Throttle" temperature for your 10900K is 100°C, the consensus among well informed and highly experienced reviewers, system builders and expert overclockers, as well as Intel's Engineers, is that it's prudent to observe a reasonable thermal margin below Throttle temperature for ultimate stability, performance and longevity. So regardless of environmental conditions, hardware configurations, software workloads or any other variables, Core temperatures above 85°C are not recommended.

Yep... that's what I read and is why I didn't push my OC past 5.2ghz...

If you have the means, I highly recommend LG's OLED panels... good luck!
