I recently bought a cheap Asus x Noctua 4080 Super on Ebay and Ive been obsessing over making my builds even quieter ever since. I thought that it would be nice to share my modifications with you guys, because I know that a lot of people own this case in this community.

Issue nr. 1 -> Front fan turbulence:

This is how I mounted my fans so far. I have identified two sources of turbulence in this configuration: The mounting brackets behind the fans and the wood grills in front of the fans. You can see how much the 120mm rails overlap with the fans.

First thing to fix were the mounting brackets:

I used a dremel with a cutting disk to remove the excess metal. Make sure to insulate the rest of the case like I did here if you wanna do this yourself.

To reduce the turbulence coming from the wood grills I mounted the fans on the backside of the mounting rails, instead of the front:

This modification reduces GPU clearance by a bit, but its not a problem with the XL variant. The front fans are much quieter at high RPMs now.

Issue nr. 2 -> GPU coilwhine. Sadly this cannot be fully fixed, but it can be reduced by undervolting and dampening the case. I dont use top fans, so I closed the top of the case with noise-absorbing mats:

Before...

...and after! I used Silverstone SST-SF01 dampening foam. Because the coilwhine is so high-pitched, even thin foam mats prevent it from escaping through the top. Its significantly less audible from my desk now.

And this is how it looks from the inside. Rather clean if I may say so myself :). You can also see the inside-mounted fans here

And this is how it looks all put together. You cant really see the modified front mounting or foam mats through the grills.

All in all the system is much quieter now, but more importantly to a Noctua owner: It makes a more pleasing sound now, less howling and whining.

Let me know what you think!
