Heat problems with 13900K

Hi@ll, here I present my new toy:



Hardware:

- Asus Maximus Hero Z790
- Intel I9-13900K
- G.Skill Trident Z5 RGB DDR5 6400MHz 32GB 2x16GB CL32
- G-Force RTX 3090 EKWB
- Samsung 980 PRO 1TB
- Lian-Li O11 Dynamic EVO
- EK-Quantum Velocity² D-RGB - 1700 Nickel + Plexi
- Thermal grizzly Contact frame
- EKWB EK-Quantum Kinetic TBE 200 D5 PWM D-RGB
- Radiator 240 EKWB EK-CoolStream SE 240
- Radiator 360 EKWB EK-CoolStream SE 360
- Fans Corsair ML120PRO x8

The loop is:

Pum/Deposit => Rad 240 => Rad 360 => GPU/CPU (in paralel) => Pum/Deposit

BIO is configured with default parameters except XMP profile (6400)

First problem is CPU gets 100 grados running cinebench R23 and thermal throtling starts (P-cores starts at 5500Mhz and E-Cores at 4300Mhz and end in 5200Mhz and 4100Mhz respectively).
Second problem is poor water flow (there's a flow meter in the loop) but the installed pump should be enough.
2 rads should be enough to cool the cpu (in most of youtube videos they're using a 360 AIO)

Ideas?

thnx in advance

Well,

After spending all weekend beeing a plumber and adjusting BIOS config, It turned out that the problem was BIOS config.

Using this guide:

https://www.overclock.net/threads/asus-maximus-z790-extreme-and-intel-i9-13900k-a-tuning-guide-for-b...

I have tammed the beast.

Final result:


Â* Â*I tried the loop with one rad (360), serial and parallel. Finally I kept two rads and CPU and GPU blocks in parallel because the temps are almost the same (on serial config the temps are 2º lower but tubbing is a lot easier).


Final bios config:
- P-cores: 57x2/56x4/55x16
- E-cores= 46x2/45x4/44x16
- VCore: 1.19
- CPU wats: 240W

Full load temps:
- CPU: 83º
- GPU: 63º

Thank you @ll for your help and comments!
Which specific setting did you change in the asus bios?Â*
