Aurora R11, runs dangerously HOT! 100C/212F?
I got my Aurora R11 (i9-10900F / RTX 3090 / 1000W PSU) 2 days ago and it failed to boot because it tripped my AFCI breaker (arc fault) all the time yesterday. I decided to move it to the living room today to test because my living room breaker is not AFCI.
It booted up fine, and I was able to set it up (this proved the PSU was arcing and tripped the breaker). Then I decided to play Alien Isolation and immediately upon entering the game (not title screen but actual walking around), the R11 case fans started spinning mad... sounded like a jet engine on a plane about to take off.
I couldn't bear the excessive noise so after about 3 min I shut the game down, installed CPUID HWMonitor, and started the Metro Exodus in-game benchmark. The following is the result:
The benchmark run was quite short but the fan noise was again, tremendous. During the benchmark run almost all CPU cores reached 100C/212F. GPU peaked at 73 C/163F. My living room ambient temp is 20C/68F.
The resting temp for the CPU is also as shown, 45C/113F, which I took about 3 min after the benchmark run.
Benchmark FPS ranged from 41 - 105fps. The min is so low because the PC thermal throttled (I guess).
This is crazy. I bought this package with the air cooler for the CPU. I know it's not ideal but it was the default option for the CPU chosen. I had a bad experience with liquid cooling before (not much cooler and loud) so.
This is pure danger and I don't know how this passed QC for a gaming PC. Does Dell at least test the PC for safety before shipping it out?

Air cooling is the issue with that build. Dell uses a low profile cooler in a less than ideal case, restricting air flow.
On top of that they hinge the PSU on a contraption that puts the PSU right on top of the CPU, causing an even larger restriction of air flow on and around the CPU.
Low profile cooler + poor airflow = high CPU temperatures.
This board has multiple postings about high CPU temperatures with air cooling.
This case and setup needs liquid cooling to be able to perform to it's proper spec. Without it you get what you have.
I 101% agree Dell should not sell systems that cannot cool the CPU down to proper levels. This system obviously cannot cool itself down properly.

But maybe a Noctua NH-L12S would fit?
No chance, my friend . . . 54mm height max with the swing-out PSU contraption. Hence, the liquid cooling requirement.

You CAN aircool an i9 10900F, but not with the ridiculously small cooler Dell includes with it. I put a Noctua NH-U9S on my 10900F (in a G5 case) and it keeps it under 25 at idle and 65 in games. Zero throttling and very quiet.
Not sure if you have space for this in your machine though because of the way the PSU folds over the CPU in the Aurora. But maybe a Noctua NH-L12S would fit? You have to measure before you buy.

Ouch! Then liquid cooling it is.

I seem to recall someone who removed the PSU swing arm contraption from the SFF case

Now that's just crazy talk. Nobody would be that twisted

If you are going water cooled make sure you order the VRM heatsink otherwise you may trade one problem for another.

Thanks everyone for responding. Since this is my first ever Dell computer purchase, and I've yet to receive any response from Dell for a question I sent yesterday, I'd like to ask a few Dell warranty / service related questions here hoping anyone who has experience can help.
I seriously want to keep this computer because I waited so long for this RTX 3090 R11. I cancelled an MSI RTX 3080 computer for this and if I have to return this R11, I won't be able to buy that MSI computer again because it's out of stock atm. This is something I want to avoid.
So here are the problems I have with this R11:
So in order to keep this computer, I need to resolve these 2 issues. And I don't want to void the warranty doing so. Here are my questions:
I read on another thread here so I know Dell can swap out a faulty PSU. But I also want to change whatever is necessary so that my R11 has adequate cooling. Right now I cannot use the computer at all for the purpose I bought it for.

Hi @samvanity and nice beast
1. Someone else had the AFCI breaker problem, maybe you need to replace the breaker
2. I would get onto Dell aftersales, order the CPU cooling and VRM heatsink. I believe Air-cooling is pointless too in the nano-case.
3. If you still have airflow issues, add an upper front fan in the HDD bay on a Y cable with the front fan
My 3080 is aftermarket and not a blower and was causing CPU temp problems. I did resolve my 100° CPU to 80° with this intake fan, not enough for me, out of warranty I eventually rebuilt around my GPU in a new case --> 50°.

Dell doesn't sell a different size case for the R11, just the 2 color options.
They will replace parts that Dell determines to be defective under warranty. I doubt they will do a free upgrade under warranty from air to liquid cooling. You can buy the AIO from them and self install though.

How about something like this? https://www.newegg.ca/cooler-master-masterair-map-t6pn-218pc-r1/p/13C-000X-003C8 (40 mm) or this https://www.amazon.ca/Cryorig-Flow-Heatsink-47mm-Mini/dp/B0177GTV9U (50mm)
The second one is supposed to handle 95W CPUs according to what I read on some forums.
Might be a cheaper solution than buying the (probably overpriced) Dell AIO.

@bertro514 How about something like this?
Air cooling only works well in a case with a good air flow regime . . . and that ain't the Aurora series. It also appears that @samvanity is looking for the best solution . . . not the cheapest. The best solution to the overheating issue is a Corsair H60 AIO liquid CPU cooler and 4 quality, quiet case fans; either Corsair ML120 Pro or Noctua NF-A12x25 PWM or a combination of those (4 fans in total).
For the PSU problem, triple check the AFCI breaker to confirm that it is not the source, before having a Dell tech come to swap the PSU. I would not let the Dell tech install the AIO liquid cooling or case fans. Do that yourself.

@Anonymous got it! And here I was thinking my G5 case takes the crown for worst airflow. I had no idea the Aurora had bigger airflow challenges, especially since Dell positions it as a machine for serious gaming. How is one supposed to do serious gaming when a basic requirement such as cooling and airflow is not met? I was this close to getting an Aurora instead of the G5. The price difference for the same config is what stopped me. Looks like I dodged a bullet.
@samvanity regarding the VRM (Voltage Regulator Module) heatsink. I recommend getting that, especially if you're in the US where you can order it from Dell for like $5 with free shipping (here in Canada I ended up paying almost $40 CAD total from Amazon US). The VRM components are on the motherboard close to the CPU and they won't be cooled by the CPU water cooler, you'll have to rely on the airflow in the case. As the CPU draws more power, the VRM heats up. It can take way more heat than the CPU, but it's still a good idea to help keep it cool. One sign that the VRM is overheating is when you run CPU-intensive tasks and the CPU seems to be at a decent temperature but the PC abruptly shuts down. That's the VRM reaching 105 degrees (or 110, not sure) degrees and shutting down to avoid damage. Very unlikely in normal gaming, more likely if you run really long CPU stress tests or rendering (I'm talking many hours here).
If you use HWinfo to monitor your temps, take a look at the "VR VCC Temperature" sensor. Mine right now is at 44, while the CPU is at 23, so it runs hotter than the CPU normally.
Some high-end motherboards even add a tiny fan on the VRM heatsink to keep it well cooled.

again, thanks everyone for your help!
@Anonymous , about the 4 case fans - so, I replace the front fan (1), buy the Corsair H60 and create a push pull sandwich (2,3), and so where do I use the 4th fan?
And with what you said installed, do I still need the VRM heatsink @F8Dragon mentioned to avoid a different issue?
Another question, does the Corsair H80i v2 work even better because it looks like it comes with a sandwiched radiator and I can monitor and adjust the fans with Corsair iCue to keep them quieter if I want to?
And yes, I'm looking for the best solution that I can apply myself to still stay within warranty. I mentioned asking Dell tech to do it for me because I don't know how Dell warranty works when it comes to replacing components myself.
This is getting ridiculous a customer has to worry so much just to get a new and expensive product working as intended...

@markburv looks like an interesting project for sure! I used to build computers myself back in college. It's been 10 years and I'm out of touch with a lot of these things. Eventually I will need a new case I'm sure, but I just got the computer ... I just saw how the PSU in R11 works and I'm like (insert profanity here)...
