Sound Blocking for Noisy Gear in a Cabinet?

I wasn't sure where to post this, but thought I'd start here.

I recently added some Luma Security cameras and a Luma NVR to my home, as part of an overall home automation project, and the logistics were such that I had to place the NVR in my Theater Room, in a cabinet housing some of my other AV gear. The problem is the NVR's fan is unexpectedly quite noisy, with no apparent means of directly lessening it.

I'm attaching a photo to show it, in the 2nd slot from the top.

I'm thinking of using some type of sound-blocking foam or other material, placed in the front and sides of this slot (leaving the back open) to at least reduce the noise significantly. The unit actually runs quite cool, so I'm not concerned about heat build-up. In fact, given how cool it is, I wonder why they seem to have maxed out the fan!

I've looked at egg-crate type sound insulation, MLV sheets, etc., but I'm not sure what would work best. I would just need to cut pieces to form a "u-shaped" barrier around the device, occupying the full vertical space of the slot.

Any suggestions or ideas?

Thanks!

there are a couple of YouTube videos of guys replacing fans with success on Luna units. If the sheet metal is vibrating you can also add some self adhesive Dynamat Extreme (or generic equivalent) dampening sheets on the inside out of sight.

Thanks for the reply, Jeff.

I did a fan replacement on my iNuke 6000, which helped a lot. But I'm reluctant to consider this on a brand-new device, which would undoubtedly void the warranty should problems of any type develop down the road.

So my first choice would be some type of local sound blocking material around that specific shelf. Any ideas on that?


ETA:
This seems to be pure fan noise; I don't detect any metallic vibration.
