Guys a question about CPU temperature.
Coming back to AMD after many years of Intel and today I've put together 3600x, Asrock B450 Pro4, HyperX Predator Black 16GB DDR4 3200MHz CL16 and Noctua NH-D15. Windows 10 November, updated, latest AMD chipset drivers.

But I'm puzzled about CPU temperatures. Just writing here in forums and it's jumping from 43-61°C.

temp.jpg


Playing a game and hits 78°C.
Running 5 minutes prime95 Small FFts hitting 84°C.

Cooler is fine. I've even dismounted it and mount it again. Basically no difference. And fins are mildly hot so it's doing his job I guess. I even run 1usmus Custom Power Plan but same temps.

So I want to know if it's something wrong or those are usual temps for Ryzen on air cooling.

Thanks.

Do you have the latest BIOS also?

If you touch the fins during some idling or browsing/watching videos then its ok to be mildly hot. If that was during those 78/84C readings while the load is constant that it could be an indicator of not proper heat transfer between CPU and heatsink.
I can see that you min temps are high too...

Can I see the whole page of HWiNFO page of

1. Idle readings without any bench

2. during some heavy load

Nothing wrong with that? 84C during torture is perfectly fine, its the hottest you will see and within spec.

Yep, latest BIOS was flashed even before installing Windows.
And yes, fins were mildly hot on desktop usage not gaming.
Below some screenshots.

Thanks. :)

LE. Case is Antec P182 with one exhaust fan low RPM. Room temp 22°C

Yes I forgot to aks this...

And @burebista you should update the system specs in your profile also.

While it is whithin specs... if he can improve it some how its a win situation.
ZEN2 throttles on 95C and shuts down on 105, but over 50C cuts down PBO. Up until 95C its just PrecisionBoost without PBO.

Understood and have at it, but the question was only if that was problematic / something wrong ;)

Yeah, I know but I just finished mounting all that stuff a couple of hours ago. I'll do it.

And I've put some LE on my previous post.

That's perfectly normal for 3600x, mine with a nh-d15s does that so you're well within spec temps. I would recommend manually setting fan speed in bios so it doesn't whirr up and down if you haven't already done so. The 3600x runs hot imo but max tdp is 95 degrees so it's well under shutting down under stress.

I'm a silent guy, only one exhaust fan at low RPM.
And also only the middle fan on NH-D15.

LE: ooby, I did manually set a fan curve in BIOS because those suddenly ramping fans at those jumping temps were driving me crazy. :D
Thanks for input, glad to know that I'm not alone at it looks like those temps are somehow usual for 3600X.

Well, only one fan exhaust is a big NO for me but thats your case.
And by other temps (VRM/board) I see that they are ok. You need better CPU cooling and maybe not the whole case. I wouldnt like to see mine 75+ even if it is within specs (<95C).

If you see you PPT/EDC readings during P95, they are way down far from limits (%). Meaning that the CPU has more to give but constrained by temp...

Hmm, so these things are hot it seems.
I'll try someday to put the second fan on Noctua and another one on intake but TBH there are too much fans for my like. :(
LE: BTW guys, thanks for advice. It's always a pleasure to ask a question here on TPU. :toast:

When you add those 2 fans do a PPT/TDC/EDC comparison, maybe post it here like the 2 screenshots before and we will see if we can do anything to improve things further. I've done a lot PBO testing lately (with manual setting) and found some things...
But take the screenshots with the exact same way to be a valid comparison.

more cache and cores under load typically means more heat to dissipate

Also, I would use the second Noctua fan on the D-15 as I doubt you could hear the difference between one and two fans on it in your case

It'll probably make no difference, the bottleneck is the chip itself. It's 7nm and it's thermal density it's a lot higher, higher temperatures are to be expected.

This is a 2600X with 120 AIO from Arctic Cooling at idle. Your temps seem fine and normal. My temps fluctuate somewhat wildly when CPU starts working on something. Had fan ramping issues so I fine tuned fan curves and no more fan ramping issues. Just get some low speed Noctua fans to add to your case to keep temps down a bit more.

While this is true about density, meaning that the die(from) has less area to dissipate the heat (to) the IHS and heatsink, there is always room for improvement. Not all ZEN2 run as this hot.
They just do better with highest possible heat transfer rate to the heatsink (TIM material/application and mount issues). Higher cooling solution alone will not do the job the best way.

if sound is the only motivation to keep fans out of your case, maybe look at installing sound deadening material which wont interfere with airflow if done with common sense. Using a software fan controller helps that will control how high fans ramp up when gaming or for other high cpu usage conditions. BIOS fan profiles are ok but that only gives 2 or 3 step points.

Small update in this morning.
First of all I'm dumb as brick. I put the Noctua fan wrong when I dismounted cooler. It was blowing in case. :banghead:
Now I put another Noctua as intake fan and tweaked a little fan curves (in idle CPU fan has 1000 RPM in idle and intake/exhaust 800 RPM and in load all 3 are at +1300 RPM).
Unfortunately I cannot put second Noctua fan on cooler because RAM clearance. Maybe I'll do some DIY with a 120 fan someday.
Room temperature is the same 22°C .
Something has changed.

Idle temps are down in 30's°C
idle2.jpg

And load temps are 79°C (Small FFT's for almost 10 minutes).

At least 7°C showed both in idle and load and looks like PPT/TDC/EDC are up too. Me happy now.
But I want to go further. In my youth I was a big fan of underclock/undervolt. Now underclock doesn't bother me so much but I want to try to undervolt.
Unfortunately I have more than 10 years since I didn't touch an AMD rig so I have no clue about how to do it on Ryzen.
So bear with me and please give me some directions for undervolt this CPU.

Thanks again. :respect:

Vayra, coming from a Sandy Bridge which was doing prime95 fanless at 65°C in the same case I'm a little puzzled about new Ryzen temps. If their are fine then perfect. :cool:
Sandy Bridge was notoriously easy to cool, it had a golden combo of architecture, soldered heatsink and lower density (32nm) than current CPUs. Things got worse progressively temp wise; when Intel moved to Ivy Bridge just one shrink later *and* moved from solder to another TIM temps and heat dissipation became an issue.

This trend has continued over the years, and even though we're back to soldered CPUs again, temps are still on average moving closer to 'max spec', OC headroom shrinks due to temp walls and voltages are pretty high out of the box.

However, we also have more experience with temps and endurance of silicon and the general experience is that they always last way beyond expiry date. So there is headroom to use, and higher temps is one way to do that.

About case fans: more case fans at lower RPM will result in a more silent build. Something to consider ;)

Small update in this morning.
First of all I'm dumb as brick. I put the Noctua fan wrong when I dismounted cooler. It was blowing in case. :banghead:
Now I put another Noctua as intake fan and tweaked a little fan curves (in idle CPU fan has 1000 RPM in idle and intake/exhaust 800 RPM and in load all 3 are at +1300 RPM).
Unfortunately I cannot put second Noctua fan on cooler because RAM clearance. Maybe I'll do some DIY with a 120 fan someday.
Room temperature is the same 22°C .
Something has changed.

Idle temps are down in 30's°C

And load temps are 79°C (Small FFT's for almost 10 minutes).

Thats better...

If you want to just under volt you can try with a negative offset to Vcore. I'm not familiar with Asrock BIOS but somewhere there is the voltage control (Vcore) of CPU on auto mode and the offset (Dynamic Vcore) on auto as well.
You must set CPU Vcore to normal and then give the Dynamic Vcore some negative value like -0.00625V or -0.01250V or more.
The -0.00625 is the smallest step.
Some CPU can sustain same boost clocks even with -0.02500V or -0.05000V. My CPU is not so great in terms of silicon quality and looses performance(clock) even with -0.01250V.
Your 3600X is definately better silicon and you may achieve some further temp reduction without loosing clock/perf by undervolt.

But I dont have high temps anyway (max60~65C and 50~55C gaming) so it didnt matter to me that I couldnt use undervolt without loosing performance. So I tryied to do the opposite, and see if I can gain some clocks. Not with positive Dynamic Vcore but with an entirely different approach.
Through manual PBO settings of PPT/TDC/EDC and Scalar.
R5 3600 PBO limits/defaults
AutoPPT 88W (Package Power Tracking)
AutoTDC 60A (Thermal Design Current) = max current on thermally constrained scenarios ~95C)
AutoEDC 90A (Electrical Design Current)
Auto Scalar X1

I was watching with HWiNFO those numbers during CB-R20 and it was like this:
PPT 87.5W
TDC 49.1A
EDC 78.5A
CPU avg(column) average effective clock = ~3971MHz

Because the temp was good enough (~63C) the CPU was doing all it could and it was capped by PPT limit of 88Watt. Raising the PPT limit alone does not help. It was still around 88W. So I tried to lower the current (EDC) starting with 73A.
Next R20 run:
PPT 87.5W
TDC 49.1A
EDC 73A
CPU avg(column) average effective clock = ~3972MHz

Keep reducing EDC until 65A.
Next R20 run:
PPT 89W
TDC 49.7A
EDC 65A
CPU avg(column) average effective clock = ~3985MHz

Then PBO Scalar into the game...
Next R20 run:
PPT 91W
TDC 49.7A
EDC 64A
Scalar X2
CPU avg(column) average effective clock = ~4000MHz

Lowering EDC alone has raised a bit the Vcore by it self. Setting Scaler from auto to X2 raised it a bit more so thats why the increased clock. Temp went up 3~4C.
Reducing EDC to 63A and maximizing cooling (AIO extreme profile and TIM change to liquid metal = drop 6~7C) has benefit even more the clock.

Next R20 run:
PPT 93.7W
TDC 51.3A
EDC 63A
Scalar X2
Max cooling
CPU avg(column) average effective clock = ~4033MHz

Your CPU has the following limits.
AutoPPT 128W (Package Power Tracking)
AutoTDC 90A (Thermal Design Current) = max current on thermally constrained scenarios ~95C)
AutoEDC 125A (Electrical Design Current)
Auto Scalar X1

It appears that you dont hit any of those limits because even tho you drop the temp, its still high enough for it to not raise clock/voltage by it self.
These limits are monitored by the CPU FIT controller (silicon FITness controller) and are regulated in conjunction with temperature.
