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

Hello,

There's no reason a D5 would struggle there. What are your 3090 temps under load?

Check for proper CPU mounting contact and consider using a socket frame such as the Thermal Grizzly to improve surface contact.

running 3dmark spy bench gpu get 50º at most.

cpu contact should be fine. thermal grizzly contact frame is already installed.

His problem is that he is not running a serial loop so in fact a single D5 pump is not powerful enough.

I have rebuilded the loop so it runs in serial (pump=>rad240=>rad360=>gpu=>cpu=>pump) and the flow rate is the same

GPU temps suggest otherwise. A D5 at full tilt would be able to cope with this.

Check for mounting contact again, try the latest UEFI release, and report back.

Silent - go read the link I posted - there is a lot more going on here then just what is described above. I agree though (and stated that as the first response in the other thread) that it most likely is a contact plate but he insists it is not so hopefully he figures it out.

Bro............ Unless the image you posted is inverted or upside down or ????????

The block is installed incorrectly and input/output is *&^*&^&*!

....or wait is your D5 installed upside-down? ...I don't get it?

MOBO is installed upside-down? (from pic)

Please see attached pics!

pump to gpu to cpu back to gpu!? WTF!? .......NO FLOW!

Anybody seeing this? Copy that pic he posted and rotate it 90 degrees............

the chasis is a lian-li 11 dynamic EVO in reverse mode. The motherboard is upsidedown so, everything is upside down.

The inlets/outlets are correct and so it is the flow path.

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:





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!
