CPU doesn't get cooled as expected

[Schaukeljunge67]

Hello there,

 

I just recently created another new topic regard my newly built PC with the following specs:

 

Cooler (Top of Case, pushing air out): NZXT Kraken X73 RGB 360 mm AIO
CPU: AMD Ryzen9 7900x

GPU: ZOTAC 4080 TrinityOC

MB: ASUS TUF GAMING B650-PLUS WIFI

RAM: 32GB (2*16) Corsair Vengeance DDR5 5600

SSD: 2*Samsung 980Pro 1TB + 2 TB

Case: Sharkoon ELITE SHARK CA300T

 

I already tightened the pump on the CPU and I changed the cooling settings in the bios. Before it would go max. speed at 70°, I changed it so it goes max. at 60°.  My expectations were that the CPU temp. is gonna be acting similarly as before, justt roughly 10° degrees lower (I know it doesn't quite work like that, but it was worth a try)

 

Now to the problem itself:

My CPU gets too hot (for my liking) and doesn't get cooled down properly. I tested this with a few games and the cooler doesn't do as well as I'd hoped. Also, it's different for each game, so here are the scenarios:

 

1) Cyberpunk:

Start-up of game is fine, playing the game the temp. is around 70-75° and rarely spikes to 80°. This was before and after changing CPU fan settings. CPU usage is at 10% max. the entire time.

 

2) Hogwarts legacy:

Start-up of game the temp goes up to 92-95° because the CPU usage is at 100% momentarily. Now, sometimes this spike is a bit longer and the cooler just can't seem to handle the CPU temps at 100% usage. It is kinda scary to me, because I would imagine/expect the cooler to be able to handle the CPU at its full capacity.

After the start-up the usage goes down and the temps go between 68 - 78° during actually playing.

 

3) Horizon Zero Dawn:

Start-up approaching 90-93° at 35% CPU usage. Doesn't really cool down. Once the game starts it's between 65-75°, occasionally spiking to < 80°.

 

4) HWInfo + prime95 stress test:

 

The results are attached. I apologize, I am unfamiliar with the software and it did track everything, although just putting it into excel or similar should do the trick hopefully. Anyway, it is weird that in the beginning the temp. is at 95° and doesn't get handled. Eventually it jumps down to ~70°, after some time spikes back to 95° and then goes back down to 70 ish... and then eventually one last jump up to 95° where it stays.

 

As a conclusion:

I'd like my CPU temp. to easily stay BELOW at least 90° if not less. I heard about this Ryzen Gen having higher temps, which is generally fine with me. But this doesn't seem right, does it? I feel like it should be able to keep the temps below 90° at least, especially with the 360mm AIO... What should I check? How should I check? Do you guys need more input? Or is this maybe normal for this CPU?

@Schaukeljunge67 High temps is just a thing that this generation of Ryzen cpus has to deal with. From the beginning it's been reported that these cpus will run all the way up to 95c, with AMD insisting that it's perfectly fine and "normal".

 

I had a 6 year old FD Celsius 360mm AiO, and I upgraded to the 7800x3D fairly recently, and I was getting idle temps in the 60's, with 85c or so whenever I was doing anything. I assumed my cooler had reached the end of its life, with me swapping it out for an NZXT 280mm AiO that I have stored in my basement, with me not using it in several years (is in mostly new condition). My temps are somewhat better, but even while I'm not doing anything the idle temps range from 40's to 50's, and sometimes get into the 60's. When I play games or whatever, then it gets into the 80's.

You'll only get the best cooling with the radiator on intake as when exhaust its sucking hot air from the GPU, making it less efficient.

 

Also depends how good your intake airflow is and that case seems to be blocking a lot of airflow with the front design.

So to summarize you bought a cpu thats known to be extremely hot, have a terrible anti-airflow case and a low quality cooler ... but, what kind of issues are you experiencing  while using this system (if any?)

Well. The issue I am facing is that the CPU is too hot for my liking. I was aware of the CPU being known to get hot. However, I was not aware of the case having a bad airflow design and the cooler being low quality. I am just trying to figure out if this is normal, and if not, how to fix it.
So I'm trying to get info out of your comment:
Basically buy a new case and/or higher quality cooler or live with it?

Okay thank you, I will take the time on Monday/Tuesday to flip radiator + fans and see if anything changes. Can that make a big difference?

Thank you, that is "good" to hear. I will wait for other responses and try the suggestions. Worst case is me being ordering a new case and rebuilding the pc in there (if I can actually expect a change in temperature). For the time being I will accept it.

Hey,

Linus covered the NZXT AIO issue in the latest CPU Cooler Vid 11min10sec mark. Where if you haven't installed the NZXT CAMpanion software https://nzxt.com/software/cam your AIO is running on Silent mode by default, hope this is your issue too.

basically... get a new case first (with front mesh)...  the cooler may be poor quality but cooling itself should be adequate,  it just doesn't help in a bad airflow case...

7900x has a target of 95c so your temps are perfectly fine.

the issue with the prime95 stress test: is simply that the CPU is hit hard and the cooling needs to kick in and reduce the temps.

But I would agree that the radiator will perform better for cooling the fluid if you pull ambient air over the fins not just blast them with the hot air inside the case.

yeah this, OP is probably fine even with the awful case, just doesn't realize that the cpu is designed that way and that "stress tests" aren't normal usage.

It should help some, but the problem with intake from the top is the hot air still needs some way out which will be the back, which means that hot air can still be sucked back in.  Its why on the front intake is desirable as its furthest away from the exhaust.

Thank you so much! I tried flipping the cooling around and saw little to no change. I built it the other way around again because, well, looks... Anyway, after doing this I saw a noticable change in temps between 3-5°, just what I wanted. Thank you so much, I (obviously) didn't think of this. Thank you to all the others as well.
