Ryzen 3900x is running too hot.

[Bioshock_0291]

I recently got a ryzen 3900x for my 3d workload.
I am running it on X370 auros K7 board with 32gigs(3200)  memory.
For cooler I am running a Kraken M22.
I am running everything at stock and am very happy with the performance.
However the only thing concerning me are the temps. 
Idle temp ranges between 45-65c
While rendering (100% load) it maxes out at 95c at around 4Ghz.
After some digging on the Internet I've come to understand that a lot of people are having issues with high temps on the new 3000 series chips with the voltage drawn by the CPU being too high.
I swapped a few different coolers I had from my other systems 
-the stock prism cooler and cooler master hyper 212 led but to no joy. 
I am considering to upgrade to a 280mm AIO cause that is what my case officialy supports.
But I feel that with some modding I might be able to fit a 360mm AIO in the case.
Here's what I want to know, 
Would a 280mm AIO be enough for cooling 3900x ?
I leave my system on rendering for 10+ hours very often and sometimes for even days and I don't want the under load temps to go beyond 75 degrees.
Here are my complete specs ;
- Ryzen 9 3900x
- Gigabyte X370 Auros Gaming K7 
- 2 X 16GB Corsair Vengeance 3200Mhz Memory
- Zotac RTX 2070 Super twin fan GPU
- Corsair HX750 Gold PSU
- 1 TB Crucial M.2 nand
- NZXT Kraken M22 CPU Cooler
- Deepcool Dukecase v3 Mid Tower case.

 

PS - I know the M22 isn't quite the match for 3900x but I was running r7 1800x in the same system before the 3rd gen launch and I thought since the 3900x ships with a stock prism cooler then an M22 can definitely keep it running cool (Boy was I wrong)

And Yes I have updated all the drivers and latest BIOS.

Have You tried slightly undervolting the CPU?  Something like 0.050volts negative offset voltage for vcore? 

[Mateyyy]

I think it is somewhat expected, since I believe you'd need at the least a thick 120mm AIO to cool the 3900X. 

 

Since you'll be running your system at constant load lots of the time, I'd personally suggest you go with a high-end air cooler (Dark Rock Pro 4, NH-D15), since I think they would be more reliable, but that's just me I guess (though you'd have to make sure they would fit inside your case). When it comes to liquid cooling, a 280mm AIO would definitely work great, I don't think you'd need the 360mm, unless you plan to manually overclock your CPU quite heavily (which from my knowledge isn't too great of an option on 3rd gen Ryzen anyway).

 

I also advise you to always stay up-to-date with BIOS updates, since these could also help, as many motherboards still pump too much voltage into 3rd gen Ryzen CPUs, even if they don't need it (if you know that's the case, you could try slightly undervolting your CPU in the BIOS).

[KarathKasun]

120mm AIO will perform worse than many air coolers for long load durations.

 

I second the NH-D15.

I'm participating in the F@H challenge so I've told the F@H program to use "full" mode to farm some points, since I'm close to top 100 right now.
I have a Corsair H150i Pro with Kryonaut thermal paste under it, and fans are all set to run at 100%.

Should be enough cooling to keep it under control, but its still sitting cap'd at 95c (pump says its temp is sitting at 43c).

To those that have a 3900X, if you have Ryzen Master installed, what is the stock PPT limit, and is it being hit under these loads? That might give a better indication of how much sustained power they take.

Yes I have tried some custom modes with ryzen master utility. I manually clocked all cores 4Ghz at 1.275V. And the system was stable under load so I thought my problem was kind of solved. So I went into BIOS and tuned the same numbers but the system kept crashing under load. I don't know what I did wrong, but that didn't work for me.

So now after every bootup I launch the ryzen master and apply the same profile everytime.

The max temperature it goes under this profile is 85c.

That sounds about right for a single 120mm rad.

 

For a comparison at 25C ambient I hit about 70-75C with prime95; for my 3900X with a Noctua NH-D15 SE-AM4, with PBO on and a ABBA bios. My all core usually hits about 4.15-4.2GHz.

 

Generally speaking large air coolers outperform almost every AIO in a well ventilated case.

[Morrowgamer]

Just an update. I stopped all processes and it dropped in temps immediately.
As Linus said in his review video, the processor is designed to red-line itself.

These results are from a prim95 load:

I will get back to you on stock config...

My old Reliable HafX. But the NH-D15 cooler is probably the key to these temps.

142W limit, but you're not hitting that as you're on the current limit. You have slightly higher clocks showing with PBO off?

Might be "better" to limit the CPU power and therefore heat by lowering PPT than it is to do a fixed clock/voltage overclock. I don't know how much as that depends on the cooling. Based on power alone, a big air cooler should do well, as would a bigger water cooler.

Yeah, I got that. I was just asking out of curiosity. 

Thanks for the info man. I think I will go for NHD15 as you and other people have mentioned here.

The clock stabilize to the same point if I let prime95 settle in; that was a quick screen cap.

 

The key is the boost on the fast cores is much better with PBO on; AKA I can actually get to 4.6GHz (Even with the bios patched to abba it won't do it without PBO). At least on my setup.

I have NZXT Kraken x72 360mm AIO and my Ryzen goes to 95 degrees under load as well..

Sorry to revive an old thread, but I run my 3900x with the Captain 240 Pro AIO (240mm) on the NZXT H510i Elite, which is not really known as a well ventilated case due to the closed glass front panel, and the CPU never goes above 72C on the prime95 torture test.

 

I built this system last week, and was curious about what other people were getting for load temperatures, so I was quite surprised when I saw lots of folks complaining about their CPUs reaching 95C. I guess I should be happy with the temps I'm getting.

 

Ps.: I have a X570 mobo and PBO is enabled, no manual OC.

[CoffeeBlacker]

Sorry to repop this topic, kind of...but just got my 3900x and was a little surprised by the temps, going from a 2600 that never got over 35c or so to peaking around 98c with the 3900x.  Imo, more info is better...so here's another 3900x, under a slightly diff water setup.

 

PBO off...

 

3900x stock, f@h set to 12 cores plus gpu...A240R EK setup...So includes my gpu, vega 56 on water as well.  Setup is GPU gets cold water, then cpu gets sloppy seconds...When the 2600 was my cpu, that seemed like the right way to do it...

 

 

Sitting at 83c cpu (max over the last 13 hrs...95c)...

gpu (hotspot) 76c, gpu temp 49c (max 51), gpu vrm 58c.

 

[CoffeeBlacker]

For fun after...added a second Vega 56...and a 420mm se rad to it...and found a water block on sale for the additional 56...than duct-taped it all in to the same setup.  Re-worked the fans a bit, so air is now pushing out from the 3 140s, and for the 240 unit, i have a weird, 2x120+2x140 due to the extra room in the front of the case (also pushing out).  This completely screws over my filters which are all now being pushed against...and air-flow is fighting my psu since its trying to pull from inside the case...which i'm working on getting a new one as i'm barely able to keep the watts steady...i have a 850 g3 (which should be fine...at least short term), and its bouncing up to 800w running FAH atm...I'm also seeing voltages drop, which is the real reason i'm looking...(though who can find a super flower sf-1000f14ht, a g2, a g3...or any 1000w psu at anywhere near original pricing...everything is marked up 30%+ or sold out).

 

@72f / 22c ambient

 

Edit:

Note...power limiter on the 56's is set to 0 now...previously it was set to 15 or 25 on the old one (not sure where it was in the previous screenshot)

I know this is an old post but JESUS are you trying to kill your CPU? On my 3900X under max load OCed to 4.3Ghz I've gone no higher then 70 degrees with a 240mm AIO.
