Ryzen 3900X + Dark Rock 4 high temp

[JoNNyDRuffy]

Hi,

 

as I mentioned in the title, I have a setup with the Ryzen 9 3900X and a bequiet! Dark Rock 4.

Since the TDP of the cooler is 200W and the TDP of the CPU is around 145W it should work fine.

Though I get high temps when the CPU is on 70-80% usage.

This gets up to 80-85 C° and I think this is not as it should be.

BIOS updated?

Chipset drivers updated?

Cooler mounted properly with good paste?

The fan is spinning?

The case has airflow?

Ambient isn't 35*C?

this is normal, i have a 3900x and at stock settings, temps goes up to 85-87c under full load

my cooler is a dark rock pro 3

 

other people with similar setups, and even 240 AIOs achieve the same temps of around 80-87

[JoNNyDRuffy]

The drivers are up to date, I already did this.

Sadly no changes.

I used the shipped paste for the mount.

The fan is spinning properly.

There are 7x case fans for the Airflow. (Corsair LL140)

Ambient temp is low due to an air conditioning 

[JoNNyDRuffy]

@Moonzy So there is no way to get a better cooling?

What are you using to monitor temperatures? Can you check what Vcore voltage you're getting at load and report it here?

not the conventional way, no

custom loop seems to bring the temp down to around 65c from what i've seen, but personally dislike water cooling

 

what i do is i undervolt the cpu, mine's running at 1.1v 3.95GHz, temps hover around high 65-75c

with open case

Are you using Ryzen Master to track thermals?

[JoNNyDRuffy]

@Mateyyy Ok I'll check for the Vcore voltage. I'm using Ryzen Master.

@Moonzy  I agree with you. I dislike water cooling but only the AIO's. Never did a custom one, but maybe I should, for better results.

[narrdarr]

I deleted wrong post here....

 

Refill

Edit

Amd and Intel calculate TDP differently so that 200 TDP rating on the cool means nothing.

 

Grab a ninja5 or silver arrow cooler

 

[JoNNyDRuffy]

@narrdarr Thx for the tip.

Btw this is my Fan-Setup:

@narrdarr I think you meant the Silver Arrow by Thermalright and the Ninja 5 by Scythe, which btw is really huge!

so what's the voltage?

up to you

[JoNNyDRuffy]

@Moonzy Could not check it so far. I am still at work, but had some time to answer here. I'll be at home in 2h.

That's HWMonitor, does HWiNFO64 show the same numbers? What are you using for stress testing?

Do your front fans have clear access to fresh air (as in there's no solid front panel like on many modern cases)? Try flipping the Dark Rock 4 around so the fan on it is closer to the front intakes (you lose a couple RGB points but it should be slightly better for cooling). Also try lowering the RPM of the top exhausts.

[JoNNyDRuffy]

@Mateyyy

So this is HWiNFO.
There is fresh air access at the frontpanel.
Sadly I can't flip the cooler, because then the fan would collide with the RAM.

The top fans are new to the setup (one week ago).
They did not change anything seemingly, except the GPU temps.

According to your HWInfo numbers, those voltages are pretty darn high and likely the cause of your high temperatures. Seems as though you Mobo is pumping out far too much voltage. See if you can decrease them to 1.25v.

The VID is not the actual voltage that's going through the CPU, it's just what the CPU is requesting, but from an earlier screenshot you could see that the board is actually pushing a normal amount of voltage.

Yes yes they are..

 

Ok so after seeing you config.

Slow down fans

Top front, top middle

Increase

rear, top rear, 

 

I'm guessing PBO is on. Either disable it or set a neg voltage offset of .30 and or both.

 

 

[JoNNyDRuffy]

@Mateyyy I thought about changing the direction of the right top fan, so there is more fresh air in the case. But I wonder if this is the problem.

[JoNNyDRuffy]

@narrdarr PBO is and was disabled. The fans are all on max, because they are case controlled.

Na it would fine and worth trying if your ok with how it looks

the idea is that those fan are pull out fresh before it gets to the cooler. this was an issue with my 280x case. end up just taking the top front fan all together.

you could also switch those fan to be controlled buy the motherboard. Alos, no software controller for your fans?

[Zberg]

thoughts would be to ensure good case airflow and contact with the cooler (repaste maybe), also maybe some TG paste while at it.

 

I have same set up (DR4+3900x), I keep PBO off and fan set to silent BIOS setting so its not loud (seems to sit at 60-70% for the most part).  It never hits 80C, usually around 70-75, and it folds 24/7 at 100% utilization.  The cooler is more than enough for the 3900x stock, something else is up for sure.

Just mount the fan higher. Or use a 120mm fan.

 

Also if you're using HWINFO check what the SVI2 TFN sensors say:

Here's my 3950X as an example.

 

Quote people properly too. Multi-quote is the first option and a single quote is the second option.
