PC Processors

[verysame]

Hi there,

I've kind of gave up on using CPU for 3d renders mostly because GPUs are faster but also due to the extreme noise of my 1950x.

When I try CPU renders the temperature goes very high, the fans spin a lot to a point where the noise is unbearable and then I stop the process.

Are there any particular settings I'm missing in order to optimize the 1950x?

I tried Ryzen Master a few times. I simply applied the default setting in the creator mode without changing anything with the fear of compromising the CPU.

The box is an Alienware Area 51 - R3 with 64 GB of ram, dual 1080ti, NVME + SSD.

Is there anything here I should tweak?

Anyone?

Same story, since your yesterday post I am waiting for advice.
I have tried about three times, but then stopped, I am too scared about my CPU.

I guess we users with older CPUs don't count much...

Oh well, it was my first and last AMD anyway... farewell.

You never mentioned how your AMD ThreadRipper is being cooled?

Sounds like you have a Air CPU Cooler. AMD Recommends AIO Liquid CPU Coolers for ThreadRippers: https://www.amd.com/en/thermal-solutions-threadripper

Plus the Threadripper 1950X with a TDP of 180 Watts has a rather low Maximum Operating Temperature of 68C so you will need a powerful Liquid CPU Cooler as recommended by AMD in the above link.

You also didn't mention what Rendering Software you are using to render nor Windows version installed.

If you are using a Liquid AIO CPU Cooler than it shouldn't be that noisy unless the fans are dirty or going bad or air flow is being obstructed to the Radiator.

Yes, it's liquid-cooled.

It's been noisy since day one. There was a problem with the CPU which Dell acknowledged and then replaced. Now it's in standard levels, less noisy than the absurd level it showed at first, but still noisy.

It seems I'm not the only one. I'm reading other users on graphics software forums reporting the same issue though some say it's just the way it is. If that's the case it simply sucks.

I hoped to find here some tips on how to optimize the settings, either via bios or Ryzen Master.

I  see that you have a special Dell Liquid CPU Cooler as per your 3d GURU Thread that you opened up: https://www.ebay.com/itm/Cooling-Radiator-Cooler-For-Dell-Alienware-X51-R2-R3-Water-MVDCV-MVDCV-A00-...

It is a good chance that Liquid CPU Cooler (never heard of it before)  is not strong enough for the ThreadRipper Processor you have when it comes to rendering. Plus a 240MM or larger Radiator will probably be quieter and more efficient than that Dell Fan/Radiator on the CPU Cooler.

Have you tried to disable some of the ThreadRipper cores to see if it runs cooler during Rendering? But I imagine it will be much slower in rendering.

If the only problem you are having is that the Processor is overheating and noisy during Rendering but the Rendering software is working normally I would suggest your replace your inexpensive Dell AIO CPU Cooler for a more powerful and less noisy liquid AIO CPU Cooler if your computer case is large enough to support one.

Thanks for checking. I actually posted the wrong link as I was looking for a possible replacement and I might have mixed up the eBay links.

The cooler is actually the one from Alienware as you can see in this picture:

I kept investigating and my feeling now is that these pre-built systems (Alienware, HP Omen, and so on) all probably have the same issue when it comes to noise: it seems it has to do with the sub-par fan setup, even the new ones (Aurora for instance). Some guy actually replaced the fan for his Aurora 11 and the noise got better.

If that's the case it's just a shame that these companies make you pay so much money (I spent for mine almost 5k) and the systems are potentially good but they fail so miserably about the ventilating. Too bad.

If that is the shape of the computer case you have for your Dell PC, I can see why you probably can't install a 3rd Party AIO Liquid Cooler unless you replace the Dell Computer case.

I my opinion, I would see if you can replace the Dell computer case for a Full Tower and then purchase a AMD Recommended 240mm or 350MM  Radiator AIO Liquid  CPU Cooler.

That should prevent your Threadripper from overheating from rendering for so long plus you will have extra space for new hardware in the future.

NOTE: If you spent 5K on that Dell computer, unless you know what you are doing, I wouldn't replace the Computer case. Plus it will probably void your Dell Warranty.

So you are stuck with a noisy Dell AIO Liquid Cooler that probably is fine for normal use but for Rendering it  probably isn't very efficient at removing the excess heat generated by at 180 TDP Processor under very heavy loads.

Thanks for your insights, @elstaci

What you're saying would confirm my doubts about the quality of the Alienware.

I can't complain about the other components but this seems to be a serious oversight by Dell. Selling machines like this to then have the end-user experiencing an unnecessary noise doesn't make much sense.

I guess next time I'll go with a custom-built solution. The only reason I chose pre-built and Dell, in particular, was for their warranty policy which now I regret.
