Ryzen 7 5800x Cooling : better colling, better performance ?

[Shakallia]

Hello everyone,

I'm facing a little dilemma here concerning the performance of my Ryzen 7 5800X in Cinebench R23. From my understanding, how better the cooling, how better the performance in that bench.

So I had before a Corsair Icue 220T case, with 2 additionnal fan up as exhaust, on stock I was hitting 15900 max on multi in Cinebench R23. My cooler is a Noctua NHD-15S, max temp was around 76 degrees.

I then changed to Fractal Torrent and added a second 140mm fan to my cooler, I tought I'd have better cooling, and thus, better perfomance. But now on multi in Cinebench R23, I'm hitting 15700 maximum with max CPU temperature of 73.

I'm a bit disappointed, I thought better airflow would net me some better performance, yet again that's not the only reason I changed my case and I'm happy with my choice because my GPU temperature dropped by 7 degrees and the other components are a bit more chilled, except for the CPU.

My guess is that the lack of exhaust up (I added one 140MM fan as exhaust on the rear) whre the PSU sit is quite detrimental to CPU temp.

What do you think ?

Well 200 points can be in the margin of error in CB, did you check the CPU boost clocks before and after?

Are you looking for a better score with just CB, or is this the only metric for performance measurements?

Cinebench can be swayed by background tasks, open web browser pages and so forth, so it becomes inconsistent. Setting priority could also change the points outcome.

Hopefully you changed the case and such because you wanted to, not from a simple cinebench score.

You will at least need to close some extra programs and try again. I've seen my Ryzen 7 5800X randomly seem to boost lower. (lower core temp, but also lower score)

Thing is I always procede the same way: I close all the programms I can, I put CB in real time priority, and so on, I my results in both cases were pretty consistent, not much variation, i'd sum it up that way :

-Icue 200T : 15850 up to 15900
-Fractal Torrent : 15660 up to 15700

I find it odd because the CPU temp is actually better by 2/3 degrees in that bench, but the score is consistently lower, it should be the contrary, better cooling, better score. So I made the conclusion that the CPU cooling is not better in that case.

But Yea, I did not change the case only to get a better in Cinebench but I'd like to get an explaination as to why my CPU behave that way.

@izy : yea, CPU boost clocks are more or less the same, maybe a bit lower with the new case.

Your temps are better than mine, I usually get 81C-85C! May make someone wonder if mine may have a defect like Ivy Bridge did, LOL.

I guess I was lucky on the die lottery, or maybe your case + cooler combo. I think for that CPU 81 to 85 in benches is fine, it is rumoured to be a hot CPU.

Not with a benchmark that lasts less then 60 seconds.

Try ycruncher to build some heat up.

 

[Shakallia]

Well in my case it was a 10 minutes run.

 

[Deleted member 185158]

Ycruncher 2.5b. CB is weak sauce to that cpu.

 

[Shakallia]

I'll try that.

I hope i am not talking nonsense here so dont take this as 100% valid but maybe Noctua NHD-15S handles better temperature spikes or something like that.
Did you change (or reset) anything in BIOS? Do you have XMP enabled etc...

I get what you mean I think but I did not change anything in Bios, and I had XMP enabled in both cases.

Look at these review from TPU : 5800X
Their test setup is not far from yours
Try some of their bench and see if you get close.
The t° chart says 75° and 78° (norm and OC) with an NH-U14S using Blender
Your system seems OK for me

 

[freeagent]

You should try out a Thermalright FC140. Since you have a Torrent you might even be able to run the cpu with no fans on the cooler..

Yea, system is fine for sure, but CPU temp/perf in Cinebench was supposed to be better in the Fractal Torrent than in the Corsair Icue 220T, and its not the case. I wonder why, but I guess it all has to do with lack of exhaust fan on the roof of the case, and the fact that the PSU is up, PSU fan does not do much.

NHD-15S/15 and that cooler cooler are pretty much equal, and my temps are in fact totally fine, its just the difference between the two cases that kinda suprises me.

 

[gasolin]

Try curve optimizer -30 (if possible) with increased perfomance

Nah the TR is the better cooler. It has D15 beat in both mass, and TDP. But if you are happy then it’s all good

I'm fine with the Noctua really, its the diffrence between the 2 cases that kinda suprises me.

I'd rather let it @stock, can't complain about performance really.

Not that much difference I think

 

[eshew]

A small under volt with a +100mhz is going to bump your score more than any extra cooling will. Very easy to play around with in Ryzen Master.

But I get it, only started playing around with it after a long while

 

[Hofnaerrchen]

To get your score up in CB do a simple all-core OC of your CPU. Based on your current temps 4.7GHz should be possible with your current cooling solution - though silicon lottery might still not favor you.

As someone else mentioned: If you want better overall performance - what does not seem to be the case based on your replies - you would have to invest time in curve optimizing your CPU.

Curve optimizing ?

CO is at -30 can't go lower

Even with -0.375 (vcore offset) -30 curve optimizer and -50hz (to kep it at 4800mhz and just minimize temps a little) my score is higher then stock passmark perfomance https://www.passmark.com/

Edc 150, ppt is recommeended to be 10% higher (pbo limits)

My temps peak at 85-86c with gpu and cpu stresstest i aida64 with a cooler master hyper 212 evo v2

I'd rather not start messing with that right now, temps and performance are fine, I'm just a bit disappointed by the Fractal Torrent case for CPU cooling.
