Question CPU temperatures question

[Quarto]

Hi there,
I have built Ed recently a new PC with these specs:

AMD Ryzen 7900x
Asus tuf gaming x670e-plus wifi
32GB Ram (vengeance Corsair 16Gb x2)
Corsair ICUE H150I RGB Elite 360mm
NVME Msi spatium M480 1TB
Azza psaz 750w ATX 3.0 gold
Be quiet! Pure base 500 Black
Noctua NF - A14 PWM X2 (1 back and one up)

I have noticed that when I start to play a heavy game (like battlefront 2) Hwmonitor shows that sometimes I reach high temperatures (between 85C and 96C) and then stabilize between 78C and 84C. I don't know if it's normal. I am pretty dumb with softwares so I don't know if I should use a special software for the fans and change something. I don't even know if it's a normal temperature but I'm suspicious. I applied a thermal paste and updated all the drivers (not BIOS).Do you have any suggestions? Thanks in advance

Hwmonitor shows that sometimes I reach high temperatures (between 85C and 96C) and then stabilize between 78C and 84C

for me, anything above 65° max is high.
others may be more comfortable with anything below ~80°.

what are idle temperatures with nothing going on?

if the AIO is mounted in the front as an intake there isn't much allowed cool airflow.
i would move it to the top as exhaust.

put the 2x Noctua fans in the front as intake,
use 1x included Pure Wings 2 fan as rear exhaust,
and the 2nd Pure Wings 2 as bottom intake.

am pretty dumb with softwares so I don't know if I should use a special software for the fans and change something

are your case fans connected to the motherboard or to a fan hub?

same with AIO fans, directly to motherboard or controlled through iCUE command center and their software?

applied a thermal paste

did you be sure to remove the clear plastic sticker from the CPU plate before installing?

what thermal compound are you using, and are you sure you applied it correctly?

on a side note;
these power supplies are not intended for any heavy usage systems like gaming.

what graphics card are you using?

Seeing higher temperatures is just a quirk with how Ryzen 7000 processors were designed.

For starters, they're designed to go to thermal limit of 95C first, then start limiting itself in other ways. As a result, they run a hotter than what most people are used to. From Ars Technica:

With the new AM5 socket and higher TDP, most processors will run into a thermal wall before they hit a power wall. You will therefore see the Ryzen 7000 series, especially the higher core count variants, reside at TJMax (about 95 degrees Celsius for the Ryzen 7000 series) when running intense multithreaded workloads like Cinebench nt. This behavior is intended and by design.

It’s important to note TJMax is the max safe operating temperature—not the absolute max temperature. In the Ryzen 7000 Series, the processor is designed to run at TJMax 24/7 without risk of damage or deterioration. At 95 degrees it is not running hot, rather it will intentionally go to this temperature as much as possible under load because the power management system knows that this is the ideal way to squeeze the most performance out of the chip without damaging it.

Secondly, the chips are arranged in such a way that for whatever reason, the CPU cores are located way off to the side. This presents a problem as most coolers are designed with the expectation that most of the heat will be concentrated somewhere along the middle. See the following image:

Lastly, in an attempt to make AM4 coolers compatible with AM5, AMD made the heat spreader on the processors thicker than usual. Lapping the heat sink to shave off even ~0.8mm was enough to improve cooling performance by around 7-10C. See https://www.tomshardware.com/news/g...-seemingly-lowers-temps-by-10-degrees-celsius

As a side note, if you're only seeing a single temperature value for the processor, it's coming from the hottest part of the processor. The rest of the processor may be significantly cooler than that.

Unless you're running into thermal throttling issues, which I would define thermal throttling as the CPU unable to maintain barely above base speeds, there's nothing wrong with the processor in how its operating. However, if these numbers still bother you for some reason, then you can do the following:

• Re-evaluate the case air flow and fan speed curve to make sure there's optimal airflow. Note that the goal of case fans are to replace the air within the case. The fan(s) for the CPU cooler affects its temperature more than what the case fans will do.
• Consider getting Noctua's AM5 offset bracket, which will place the middle of the cooler over the CPU dies of the processor. However, Noctua notes that 1-3C better cooling is typically expected from this.
• Consider either setting a PPT limit or undervolting via PBO Curve Optimizer. Though this may only help with multithreaded tasks and games barely count as such.

The website's specs say that 360mm AIOs fit only at the front, but airflow is heavily restricted, due to the style/design of the front panel. I imagine not much air is getting through there, and then you have an air filter + radiator behind the panel, restricting airflow further. There's even a review HERE mentioning that airflow is on the weak side.
One can only brute force cooling so much through an AIO's fluid volume alone - they still need air to function well.
The top panel of the case at least can be opened up to a mesh panel, but you can't put larger than 240mm models up there.

Is it safe to say that you got this case for the silent function? These cases tend to sacrifice overall cooling to do that - some of them get around it by being configured for negative pressure.


TL;DR: I suspect the AIO is being choked to the point that the fluid volume can't make up for, but there isn't necessarily a problem here, due to the nature(?) of the case. Temperatures are still within the cpu's spec.

it can definitely fit a 280mm AIO in the top, but does look a bit short for the 360mm.
if the cooler is new, exchange it for a nicer 280mm .

Hi there,
sorry if Im late i had some problems these days (not with the pc fortunately). So to answer some questions:

-yes the AIO is mounted in the front since there is not space for that on the top of the case.
I bought a 360 because some PC friends told me that is way better compare to a 280 especially for CPU like this.

- I have a Rog strix 4070ti as a GPU but never had a problem with its temperatures

- I choosed this case because I've read that the be!quiet is a good brand and I love silent cases because I record a lot of VO inside my studio. However, I'm a little concerned about his front part, because it doesn't have much hoiles for airflow, only on the thin sides. I worte to the brand if i can order a different front panel that they have with more holes and that can fit with this model.

- when i just browsing online and youtube, it reaches a temperature of 54C° (eventhou sometimes it reache a high pick of 70C° but only for one sec)

- i tried to do some fan configuration with the BIOS and now under stress it reaches better temperatures (87 max), however I'm not good with BIOS so I just tried some Q-fan controls folllowing some youtube videos, but I still struggling to understand what to do

I have a Rog strix 4070ti..Azza psaz 750w ATX 3.0 gold

i would not give this power supply the opportunity to damage my card.

and if this system is new;
think about either exchanging the case for something with more options
or the cooler with something that will fit with the recommended placement.

-Oh geez... Now that one is far from true. Much of an AIO's performance is tied to the fans, and thus one's personal fan curves.
[As I mentioned earlier, you can only brute force so much through just fluid volume.]
280 & 360mm coolers tend to trade blows.

-Gpu can still get air up from the perforated psu shroud and the unfiltered PCIe slot guards.

-Be quiet has a good reputation, yes, but it's not relative to the current scenario.

-Nothing unusual there. Temperature spikes are going to happen, if it's just moving the mouse or making some keystrokes.

-When the limitation is a physical one, what you do to fix it is by making physical changes. All you will manage to accomplish through bios is kneecapping system performance to lower the temperature - you didn't acquire a 7900X to do that.
Strongly consider what @JohnBonhamsGhost posted above: "exchanging the case for something with more options
or the cooler with something that will fit with the recommended placement."
Of course, it can even be another be quiet case, like their Silent Base 802 or Shadow Base 800 FX.
