5950x Temperatures, Clocks, and Voltages

[govvern]

Hey everyone,

 

I had a few concerns regarding my new 5950x. Recently I just finished a new PC build with the following specs:

 

• MOBO: ASUS TUF Gaming x570-Pro
• CPU: AMD Ryzen 9 5950X
• GPU: EVGA RTX 3080Ti FTW3 Ultra Gaming
• RAM: Crucial Ballistix 2x 16GB CL16 @ 3600Mhz
• Storage: 2x Samsung 980Pro NVME M.2
• CPU Cooler: Noctua NH-D15 (Noctua Thermal Paste)
• Case: Corsair 5000D Airflow
• Fan Setup: 3 Front Intake, 3 Top exhaust, 1 Back Exhaust

 

PBO is off, Windows power settings are set to balanced, and Nvidia Control Panel settings are all default.

 

I’ve been running benchmarks from Cinebench R23, Heaven Benchmark, and Superposition using HWInfo to monitor.

 

Using Cinebench, I’m seeing CPU temperatures peak at 65C and hover around 61C under 100% load across all cores. Also all core voltage are right around 1.025V @ 3.5-3.8GHz. This is what I would expect to be normal behavior.

 

Now, when running Heaven Benchmark, everything is completely different. Granted, my GPU temps are around 78-82C, but my CPU temps are jumping up to 75C, sometimes spiking close to 85C! Also at 5-10% usage I’m seeing and constant 1.4V across all cores with clocks jumping as high as 4.5GHz. Some individual cores even reaching 5GHz. As far as I’m concerned this is not a CPU benchmark.

 

Another thing in Heaven benchmark is I’m seeing my Power Reporting Deviation dip as low as 55% which is really concerning since it’s meant to stay between 90-110%.

 

Again, everything is stock and I don’t have PBO or OC settings enabled.

 

This happens in games as well not just benchmarks. My most recent was Outerworlds where I saw my CPU temps spike to 86C just in a loading screen. 

 

I’m really not sure what to do here. This is the closest I’ve gotten to figuring out why my PC is running so hot. 

 

I would really appreciate any feedback.

It'll throttle at 90c. 

Top chips give top heat. And performance. Enjoy!

I’m convinced you only read the first sentence of my post…

That does sound like standard Ryzen voltage behavior. My custom water cooled 5900X, for example, runs hotter in RDR2 than it does in Prime95, thanks to how it's voltage algorithm and everything works. I wouldn't worry about those numbers.

Yup
