[SOLVED] Ryzen 5 3600 and noctua NH-D15

[samiski]

Hi!

I got a small problem.
My first pc I ever build is great and all, but the temps are bad...

I got a ryzen 5 3600 and a noctua nh-d15 on it, yes I do know it's overkill but hey - it should cool it down right?
But it doesn't.

On prime95 I get 80-83c* and I've tried a thousand things to solve it but I can't.
Until last night I found out that when I use prime95 the cpu is on 165W!!!

Isn't that like ALOT?!
Please help me, it would be goooolden if anyone could help me solve this mess :-(!
Thank you in advance

Noctua used to post TDP ratings on their coolers, but over time decided (rightly) that TDP ratings, especially on Intel cpu's, were seriously bunk, so they quit doing that and went to a graphical representation instead.

The TDP rating of the NH-D15/S is 250w+ and has not changed since its inception.

Ryzens are not Intels. They'll pretty much stick like glue to their wattage rating, even under extreme loads, because they'll throttle back on boost in order to do so. The 3600 is a 65w cpu and that's what you can expect from it, AVX or not.

PBO can change that. It's a documented fact that some motherboard manufacturers will artificially boost PBO beyond AMD stocks settings, applying a level 1 or level 2 limit instead which gives an artificial boost to cpus for testing and performance values.

Asus is the only manufacturer that flat out refuses to budge on the intel/amd settings, and as a result has a reputation for poor performance at stock, but reality is the 'stock' settings for other vendors are not really 'stock' at all.

So you can run PBO, but with that cooler, won't get better performance on an Asus board since one of the parameters for boost is temps. Unless you apply a level 1 or level 2 PBO, which changes the 'stock' values.

If you look at the top guages in the first runs, they are all perfect. PPT of 88w, cpu power of 67w, TDC of 60A, EDC of 90A.

It's the second runs where PBO limits are changed, allowing for much higher outputs.

But it performs poorly compared to other coolers when it comes to CPU temp?

, this whole thing with Ryzen 3000 and it's 'high thermal's' has really gone over the rainbow. Some users legit have thermal issues, others are making a mountain out of a molehill.

Ryzen 3000 is unique to the cpus before it - it has more in common with a graphics card - Nvidia's 10, 16, and 20 series with their Gpu Boost Algorithm: boost frequencies are determined by the available power and thermal headroom.
The more leeway available, the faster it will try to run - at the same time, those higher speeds will make it run just as warm as it did with lesser cooling, but those temps aren't harming it though.
This behavior is also part of the reason manually OC'ing on them is so poor.


To give a more direct answer to your question though: No.
Ryzen 3600 has an advertised single core boost of 4.2ghz. It runs that easily enough on light loads, but on heavy/all thread loads, it WILL TRY to run that same 4.2ghz on all active threads depending on the available power and thermal headroom.
Because of that, looking only at thermals on these cpus isn't enough; there's a need to check the boost frequencies as well.
I think you could do with a couple more chassis fans, so you can have 2 front intake and a rear and top exhaust...

If you really want both 4.2ghz all core and some 60C(I guess?) load thermals, custom cool it - but that's bad advice for different reasons...

Btw specs are:

RYZEN 5 3600
NOCTUA NH-D15
RTX 2060 SUPER
16GB RAM 3000MHZ
PHANTEKS ECLIPSE P400A - ONE CASE FAN IN THE FRONT AND ONE IN THE BACK 120MM
CORSAIR 650W SILVER 88%
ASUS ROG STRIX B450-F

That D15 should cool that easy what version of prime 95 are you running?

I would download OCCT and just click the green on button and see what your temps are that is a more realistic load and easier to do than figure out what prime 95 to run.

 

[samiski]

I am running the small test, maximum power/heat etc...
But what the problem seems to be is that it is drawing 165w which is the max of the noctua, and is what i think maybe why it cant cool it down correctly?

now the question is why is the cpu drawing 165w, when its a 65w according to ryzen, shouldnt a benchmark make it go to 70-80 or even 90w and not 165w?!

That is not saying the version and what is turned on. Run OCCT .
Their only a couple C difference in the D15 and most AIO water coolers till you get into the 360mm ones.

@Zerk2012 Ok, ill try that tonight and reply what happened - thank you !!

"but what the problem seems to be is that it is drawing 165w which is the max of the noctua"

Pretty sure the NH-D15 is rated at 220W.

 

[samiski]

@justquant You're absolutely right - my bad...
But what my problem is that I get high temps, such as 80-83 in prime95, and around 70-80 in battlefield V in high settings, which is not a good temperature for the noctua...
And why I think that is, is that it draws 165w?

Do you now any soloution for this and I would be forever grateful !

Have you mounted the cooler properly? What's your chassis? What is your case fan setup? Pictures would help.

What are you using to measure power draw, Ryzen Master?

 

[samiski]

@justquant Yes, it also has been removed and re installed to check that I didn't do anything wrong.
I am using a Phanteks P400-A - one 120mm phanteks fan in the front and one in the back.

 

[samiski]

@justquant https://www.bildtagg.se/file/bcw4bjqozb8f8sofholpdej3 the front
https://www.bildtagg.se/file/lwayi8k6u1c7nnb4w0wzgl the side

 

[Crosslhs82x2]

Try rerunning the P-95 with the AVX's checked or ticked to disable AVX's.
The Avx's produce more heat then needed for testing.

Good case there, looks like it has a mesh front which is always good for airflow...

Is the front fan lined up with the CPU cooler or is it in the middle?

As the user above suggested run Prime95 with AVX off, or use OCCT for a more realistic result.

And once again, what are you using to measure power draw?

 

[samiski]

@Crosslhs82x2 @justquant

I can do that but the problem is that even in gaming the temperatures are high.
Like in Battlefield V with high (not ultra) grapich settings I get between 70-80 degrees, which indicates that something is wrong... Not even the worst aftermarket cooler gets those temps :-(

I use argus monitor but some has recommended ryzen master for more trustable numbers, which i'll try tonight after work!
The CPU fan is lined to move air towards the GPU, not towards the Noctua

Definitely do that, Ryzen Master will give you more accurate results.

@justquant

I'll try that tonight, but let say that I still get insanely high power on my CPU, what do I do? I am not that experienced with PC's ?

Post your Ryzen Master power draw values while gaming when you are able to, and we'll take it from there

165W for a Ryzen 5 3600 is not normal under any circumstance.

 

[Crosslhs82x2]

But that can very well be false reporting.
Ryzen master and Hwinfo64 are on my 3600x the most accurate with Occt and Aida64 not ruled out by any means.

 

[samiski]

@justquant @Crosslhs82x2
Understood.
Will try both ur suggestions and I'll be back with some more info later tonight.
Thank you so much for your time guys!

Go to bios and manually change the voltage of cpu to 1.1 volt

 

[Phaaze88]

Pretty sure the NH-D15 is rated at 220W.

Could you point me in the direction of this?
Noctua is one of the few manufacturers that doesn't post TDP ratings, instead using some little chart with 4 different ratings:
-Ok at stock operation
-Low overclocking headroom
-Moderate overclocking headroom
-Highest overclocking headroom

@samiski
Folks are getting too hung up on thermals with these cpus, forgetting that on heavy loads, these cpus will try to boost all active threads UP TO the advertised max boost clock based on thermal headroom.
In the case of the Ryzen 3600, that's 4.2ghz. You should also be looking at the frequencies on all threads.

Also, why'd you change the chassis' stock configuration?

 

[madmatt30]

If a ryzen cpu were drawing 165w I'd be fairly certain that both the board and cpu would be going up in smoke.

Thats definitely false reporting there, what temp does bios report??
