Sucks that I'm not at home now, I have the fans on my 2nd rig's GPU supported with a short PETG tube. Remind me that I post a pic later.

It has an aftermarket heatsink and 2x92mm fans in a PCI slot cover bracket.

Think I already posted this, what to do if you have microATX mobo with too close PCIe x1 card to GPU? Use PCIe x1 'relocator'. Flash makes the dust looks 1000% worse lol

Though by using this it have that odd noise through the speaker when you move your mouse or do something, so I put some anti static bag around the soundcard. The PCIe power connector is properly dange around there so the anti static bag is covering the bottom and side of the card. I put a smaller anti static bag on top near the analog side of the card. No more that irritating eeeee when mouse moves.

I can't tell if that covered in ECS bags is a soundcard. Maybe get an 1-2 mm thick Aluminum sheet and mod away a way to screw in the back just above the sound card without touching the PCB underneath or MBO PCB.
To prevent Aluminum sheet to touch the PCB while sagging add a 2mm thermal pad in between towards the tail of the Aluminum sheet. Also you can seat the Al sheet on 2 thermal pads, make sure the soldered pins from the back of the card doesn't protrude trough thermal pad, you don't want shorts, even double the thickness of the thermal pad if is necessary.
Aluminum should give enough shielding.
Hope it helps.
For example on ALC4080/4082 chips the design of the MBO has flaws regarding placement of the sound and USB power passing trough or close by- USB power traces goes very close to the sound chip, resulting in interference between the the sound and the voltages required by USB.

Or just glue some rubber donuts to a couple toothpicks and accept your dongle is the predominant issue.
