Hot Temps for 5800X3D

by the looks of that the CPU gets cooled with warm water that went past the GPU.... put a rad between it... or seperate loop or back to air

Just got the x3d.

80c after 10 minutes on cinebench with -20.

Cooled by the artic freezer duo 34.

Without -20, its more like 85c.

It's pulling 110 watts more or less.

Does this seem ok?

EDIT: I tightened he cooler a bit more, temps dropped around 5c. This always happens when I get a new cpu.

But prime small ffts is a no go, instant 90c.

She’s hot.

 

[lawood]

Yeah, prime 95 is off limits with this chip lol
Now I'm trying to automate the pb2 tuner software.
I'm pretty amazed atm, i dialed in -30 on all cores and corecycler is stable for 5 interactions. I will be doing much more testing but this is a promising start.

5800X was thermally the worst Zen 3 CPU.
5800X3D has even worse thermals. Expect straight to 90C for most all-core workloads. There is no comparing to other Ryzen 5000 CPUs (Ryzen 7000 maybe).

All of these people reporting 90c temps have something wrong with their cooling. I upgraded from a 5800x to a 5800x3d (a family member needed a cpu so I took the opportunity to upgrade) and if the x3d is hotter it isn't by much. With a noctua nh-d15s and CO -30 (kombo strike setting 3) I'm idling at 42c and I've never seen it go over 78c in multi core workloads like cinebench. In my hottest running game, battlefield 5, I'm running in the low 70's. I'm having zero problems with this cpu, and I'm running on air.

Mine never breaks 75C with Deepcool AS500 + 2 Noctua NF-A15 HS fans and 75W PPT limit.

Something is wrong with your cooling if you're reaching 90C.

• People have different ambient temps - a bunch of these threads in the past year have been with 30C+ ambients.
• Different boards and even different BIOSes on same boards perform wildly differently as to Vcore and core power. 4303 BIOS on the Impact requires a very hefty -0.075V Vcore offset just to get to the same Vcore as 4006 BIOS, and still runs up to 5 degrees hotter at higher power.

It's already well-known that temp variances between CPU samples are not good. @ 2:40

Stock 5800X3D is around 110-120W. If you're already hitting 75C at 75W then I hate to break it to you but cooling needs work (assuming a sane 20-25C ambient). AS500 is a reasonably strong cooler. Most of it comes down to cooler contact and mounting.

In that video he says with normal cooling you probably wouldn't notice a difference between the two cpu's and that he's going to look into it some more probably in another video. I mean, look at that pc, it's as small as possible with everything packed in so tight you couldn't slip a piece of paper between components. There's no way these cpu's should be hitting 90c with adequate cooling unless the voltage is too high, and if you're running in a very hot environment you need the best possible cooling at the lowest possible voltage no matter what cpu you're running. It sounds to me like motherboad makers are just kind of doing whatever they want when it comes to voltage. The fastest cpu's run hot, they just do. And for people to just plug it in without any thought to taking precautions for heat seems disingenuous to me.

Hello,

5800X3D aircooled (Be Quiet Dark Rock Pro 3) with -25 on all Cores (no other changes).
When i stress (CPU-Z all Cores) the CPU for about 15 minutes, i maximum get to 75,3 °C (highest Value i ever had with this CPU / System).
[The AMD 1600X i had before was max ~ 66°C in the same System but with stock settings]

Motherboard: Asus CH VI (x370)
Power: 850 Watt be quiet! Dark Power 13
Case: Thermaltake Core X 5 (all sides mesh / Motherboard Horzontal - i hate this Vertical Mounting especially with the big CPU air Cooler and the heavy air cooled Graphic Cards).

The Deepcool AS500 is smaller then my Cooler, but with 75W PPT you should get better Temperatures i think.
How is the airflow in your System? Maybe you have additional °C by using a closed, small or full packed Case?

I don't know why it happens but my temps also maxed out at 90C when playing and only small random peaks that rarely occurs, If I stress test my CPU with benchmarks or stress tests I just can't get past 76C Max temp (pulling around 110 to 120W). All test done while benching the GPU aswell, to get a more accurate result.

Ambient temp: ~29/31C
Mobo: Asus PrimeX570-P
Case: LianLi O11 XL

Everything in a Custom loop with:
60mm thick 360 bottom rad (intake fans pull config) (EK)
30mm thick 360 top rad (exhaust push config) (Bykski)
3 more fans on the side as intake
1 fan exhaust on the back
PNY 4090 XLR8 with an alphacool waterblock (usually tops at 57C (never seen it higher) iddles aroun 31 and 35C)
Bykski CPU for the 5800X3D waterblock (iddles at 41C and tops at 90C randomly and 76C with benchmarks and stress test)

Loop is going: res/pump -> 60mm rad -> GPU -> CPU -> 30mm rad -> back to the res

Running just destilled water with an avarage temp of 36 to 38C
All fans are Artic P12 and running only at 25% to 50% for temps under 80C and 50% to 100% between 80C and MAX temp
Pump always at 25% and 50% from 80C to 100C
