Silent case for a hot & noisy setup (5900x and 3080)

[rwm24]

My current build isn't even a year old and the thermals and noise bug me.

NZXT H511 Case (same as H510 but with different usb ports?)
CORSAIR HYDRO H115I RGB PRO XT AIO
5900X
3080 Founders Edition

I replaced the fans that came with the case. Rear exhaust is now a "be quiet! Silent Wings 3 120mm" and the top exhaust is a "be quiet! Silent Wings 3 140mm".

The GPU quickly reaches 70 degrees and the computer is loud, even with closed back headphones on. Often the fans ramp up when I'm working and barely using the system (2 x Visual Studio Code, 5 Firefox tabs, Spotify) the CPU usage is only ~10%

What are my best options for replacing the case? Noise is the biggest thing for me, but I also don't want to ruin the hardware.

Current contendors:
- Lian Li O11 Dynamic XL (https://www.overclockers.co.uk/lian...ied-aluminium-full-tower-white-ca-77l-ll.html) - Might still be noisy?

- be quiet! Dark Base Pro 900 Rev.2 (https://www.overclockers.co.uk/be-q...ming-case-black-tempered-glass-ca-12d-bq.html) - Too focused on noise and thermals will be awful?

- Corsair 5000D (https://www.overclockers.co.uk/cors...-mid-tower-white-cc-9011209-ww-ca-25z-cs.html) - Balance between noise and thermals?

Any advice is greatly appreciated

I'm leaning towards Lian Li O11 Dynamic XL with lots of 140mm fans at lower RPM, as they should produce less noise?

Thank you for all the helpful responses.

I think the issue is the AIO not getting enough air and the CPU being rather hot. Hwinfo shows the "Core Temperatures" at ~55 degrees and according to iCue the pump fan is running at 2900 RPM to achieve that. The GPU fan sits ~40% and if I manually reduce that to 30%, which is the lowest it'll go there is no audible difference.

I think a custom fan curve in iCue was all I needed. This is how I have it set now:



I played Far Cry 6 for ~10 minutes and the CPU fluctuated between 70 and 75 degrees (35% fan speed on the graph) and it was quiet enough for me.

Fan #1 and Fan #2 went up to about 868 RPM:



I was already under volting the GPU and that was ~70 degrees too, fan at about 40%.

Thanks for your help alec and Drumroll.
