There is a whole industry for sound isolation in buildings, you could build a box or retrofit a closet with the products and techniques described at these sites:

mdf is actually really good for sound control.

I built a few recording studios with

sheetrock/aspahlt/mdf/asphalt/mdf/mixed foam/fireblankets

the rooms are very dead

seven layers above the foam panels were mixed.

we added the fire blankets after this happened

I think your construct could be improved by adding ducts to the outlet so the heat isn't getting trapped inside the construct. Some of it will be recirculating. (I only watched the last video).

I'm aware that air needs to get in and out of the box. Anyone who puts their ASIC in a seal box is dumbass!

MDF isn't that good; it's just easy to work with and better than nothing.

I'll look into using a fireblanket inside the box though. Thanks.

yeah they are short proof and very fire resistant. they will melt at about 1100 f but they never burn.

Yeah that was a fast build it worked but I ended up putting 3 of these fans on the exhaust end

this helped get all hot air out and did not add to the noise.

When you're trying to mitigate sound from an ASIC you need a) to reflect sounds back into the box and b) absorb sounds within the box. I've contructed a box from 25 mm MDF and lined it with 30 mm closed-cell foam marketed for vehicle sound-deadening but I'd like to do a better job and I was wondering what else I could construct the box from that would improve performance. I've read that bathroom tiles are good at reflecting sounds because they're hard and very smooth (not the textured ones, obviously) so I was considering attaching them to the inside of the box between the MDF and the foam to improve sound absorption. Does anyone think this makes sense or is a waste of time?

I'd actually really like to make something from concrete like this but it would be really heavy (kind of why I think it would be effective).
