Getting Only 21,956 pts in Cinebench R23 with i9-12900K – High Temps (95°C-100°C)

[Ancient-Act6477]

Hi everyone,

I’m getting a low Cinebench R23 multi-core score of 21,956 with my i9-12900K, and I suspect it's due to thermal throttling. My CPU hits 95°C-100°C during the benchmark.

System Specs:

• CPU: i9-12900K (stock settings)
• Motherboard: ASUS ROG Maximus Z690 Hero
• RAM: 64GB DDR5 @ 5000MHz (XMP enabled)
• Cooler: Cougar Helor 360mm AIO

Cinebench Score:

 

What I’ve Tried:

• Increased CPU Package Agent Voltage to 1.1V in BIOS.
• Increased XMP VDD and VDDQ Voltage to 1.25V.
• No noticeable improvement.

I’m wondering:

1. What could be the main reason for such a low score?
2. If the issue is with the AIO cooler, which AIO do you recommend for better cooling performance?

What could be the issue?

With this aio? Before or after the voltage increase?

How much power does it pull during a run?

 

What thermal paste does it use? Is there a contact frame?

Perhaps you'll need to check whether the aio was mounted correctly

I think both after and before increase voltage. 

 

The cpu package power in Hwinfo is around 140W max(I exptect it be be around 250W). I am also conerned about this. I have gigabyte psu ud1000gm 1000w 80+ gold.

 

I'm not sure about thermal paste because the PC was build 2 years ago from PC build shop.

 

But single core performance looks okay around 1958 pts with 52C temp.

Could be the CPU is reaching high temps are is thermal throttling itself quickly. 

 

What Windows power profile is it using? Set it to high performance

Seems power limited, my 5900X has a stronger MC but lower SC.

Yes, I verified it inside Intel XTU. The CPU starts thermal throttling instantly as soon as the Cinebench benchmark begins. Does thermal throttling limit the CPU package power? I noticed that the CPU package power never goes beyond 150W. The processor should utilize its full power, such as 250W.

 

The Windows power profile is already set to High Performance

Does power limited by PSU itself or in mobo settings? What settings should I change

Its a setting in the bios. I run AMD right now, so I cant help you there
