I've tried to day to stress test my build with cinebench on the CPU and I got high temperatures, not on cores, but on the package and CCD#0.
I have a Ryzen 7 7700X with a Noctua NHD15-S as cooler with an extra fan added (Fractal Aspect 12). Mobo is a Gigabyte Gaming X AX B650 and the graphics cars its' a Sapphire Radeo 6700 XT
I have as a case a pop XL Silent by fractal design with added three Fractal Aspect 14 PWM fans, one on the rear and two on the top pushing air outside, and the three stock Fractal aspect 12 sucking inside the air from the front.
The problem is that when i run Cinebench on the CPU for a couple of minute I got the temparature on package at a high 95.3 C, on the CCD#0 98.1 C, by the way what it means?, and the core max temp 92.4 C.
First question: are the temperatures actually ok and I'm worrying for nothing?
If not, what I could do? I was thinking about inverting the upper fans, or try to repaste the CPU. Any other ideas? It's possible in some BIOS setting telly to do a less aggressive ramp up of the clock?
PS: there's a pgoto of the build, if you'r einterested.
Hi, @mike71 (nice to e-meet you).
I have some information for you.
CCD stands for Core Chiplet Dies (CCDs). A CCD, sometimes also called a "chiplet", is a cluster of eight CPU cores that share access to a common L3 cache. Some AMD CPUs, like the Ryzen 7 7700X and Ryzen 7 7800X3D, have one active CCD per physical processor. Higher-end chips in the Ryzen 9 Series have two active CCDs, typically referred to as CCD0 and CCD1.
Your temps are a bit too high. I suggest you start by checking to see if there's enough thermal paste on the CPU itself. It can get a little messy, but a great place to start troubleshooting. Make sure it's spread consistently across the surface of the CPU.
Your Noctua NHD15-S has plenty of heatsinks (the larger the surface area the higher the heat dissipation), so I would worry much about this device, as long as it is resting on the CPU, and, again, there's enough thermal paste. By the way, is the 140mm fan working/spinning?
About the airflow, check out this picture, it clearly shows how the air should flow in and out of your rig:
Simply put, you're looking for the Push-Pull effect (air being pulled into your case from the front panel and pushed out from the rear and top of your case).
You've done a great job in cable management, the inside of your rig looks pretty good to me, but be sure that the rear fan is actually sucking the heat from the CPU cooler out of the case. Just double-check the orientation of the fan.
Lastly, as @BigAl01 mentioned, consider going with an AIO...
I'm back after a week but I bought some stuff and had some problem to make progress.
I bought some new thermal paste from Noctua (because I lost somewhere the old syringe and the offset bar that Noctua suggest to use with AM5 Ryzen CPUS.
Now: this was the CPU when I detached the cooler:
Then after mounting the offset bars:
And while I was remounting all the stuff I noticed that on the top of the intake fan on the front the Pop XL Air Silent has a gap. I closed with some electric tape to make sure that the upper fan isn't sucking air from the inside.
Now the results:
Without the front panel:
With the front panel:
Having the front panel on means an 1.5 increasing on core temp but more or less same peak CCD#0 temps.
Themerature are a bit lowe and I newve seen peaks of 98 C as before, so for now it's a meh result. What I noticed is that the peak on CCD#0 happens when I try a screensot of HWMonitor with Cinebench running, as if something interferes between those programs.
The other suggestion I have to follow is to get a Noctua fan and use it, to having more cooling rather than with the Fractal design fan that runs at 1200 rpm insted of 1500 and it's smaller.
From what I've gathered, the Ryzen 7 7700X in normal operation has a thermal throttling at 95 C, and sometimes it overshoots.
I' ve found that it's possible to enable the ECO mode, that power limits the CPU. Unfortunately in Gigabyte BIOS it's hidden under a submenu, AMD CBS->SMU Common, that is quite counterintuitive. With that limitation the maximum temperature it's 81 C but the performance hit meauserd with Cinebench isn't too big.
At the end, using the offset Noctua bars for the AM5 socket helped a bit, and maybe also the repasting. But using the ECO mode helped a lot more to sta at lower temperatures.
