Are these readings for a 5800x with AIO during cinebench r23 normal?

Hi all

Not really a tech support question, but want to know if these readings and temps are normal with an AIO on a 5800x. Below are the details:

CPU: 5800x with PBO set to auto. Haven't configured anything else in BIOS except XMP. Thermal paste: Thermal Grizzly Kryonaut RAM: GSkill Trident Royal Z 32GB running with XMP profile for 3600 speed and 16-16-16-36
Ambient room temp: ~75-76 F AIO: Liquid Freezer II 480, fans replaced with Noctua NF-A14

Cinebench multi-core score is 14435

Highest temp. reached in HwInfo64 v7.14 was 84.1C on CPU (Tctl/Tdie)

Clock speeds were all at 4.469 Mhz throughout the test.

Is this normal or would you expect the temps to be lower given the cooling setup and no additional OC being done?

Thanks in advance.

Yep thats a bit hot for that clockspeed and score.

Your score seems low, I get between 15.9 and 15.75 without PBO, and I have the lesser Artic Liquid 360 AIO, (although it really doesn't matter in CB).

Have you tried without PBO, and with all background programs closed?

Btw, don't focus on the clock speed, instead watch the effective clock speed.

Exactly what mine is showing with a 280mm AIO. It’s completely normal for the 5800x and you will often even see spikes to high 80c in normal use. Gaming it will usually run around 70c

But 14.5k @ 4.45ghz is a bit low comparing to the heat. Mine gets 15.8k @ around 4.7 GHz with temps aroubd 75°C . But thats also a custom loop

75°C is equivalent to 167°F, which is 348K.

I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand

Now that you say it I thought 4.6 is the standard. I’ll run a quick test to check mine

Ok. Everything stock with 280 AIO I have all cores clocked at 4.25/4.50 . R20 score of 5801. Peak temp 83c

Your PBO power limits are probably set high by your motherboard, which will make it run hot. The 5800x is also notorious for running hot because it has one core complex vs two on the 5900x and 5950x. As long as that Tctl/Tdie is below 90c, you're fine.

I would have to agree with you that the 5800x core complex design and architecture contribute to the higher thermals than the 5900x and 5950x.

My 5950x with an overclock hovers around 78°C after 30 minutes of sustained full load. I think the dramatic difference in thermals for the 5950x is at lower usage. The temperature dramatically increases between 5-20% usage into the low 70's. Then plateaus.

78°C is equivalent to 172°F, which is 351K.
