Sound absorbing mat or isolation pad for desktop PC

I'm looking for some kind of sound absorbing mat or isolation pad (or material) to slip under my desktop PC so that it doesn't transfer a low level hum to the desk.

Ideas?

Thanks!

Probably some generic gym mat would suffice.  There are anti vibration pads for washing machines - but those are pretty thick...it would depend on your case feet if they fit.

Mine is on the carpeted floor, so no issues.

I know what you mean - I have had external hard drives hum irritatingly on my desk.. I'm like what is making noise now!?!!

Is this your fans? You might want to look at the fan profiles if you haven't.  In a newish system there isn't really anything else in motion.

On that note, I'll suggest looking into Yoga mats. They seem somewhat on the "reasonably thin" side. I've never owned one myself but I've seen a fair number of people cut them up for alternative uses like shelf or drawer liners.

The foam insulation you use to sound deaden cars would work but you don't need much. I guess the sound is transmitted by the four feet. try putting a thick insulating material like a strip of foam draught excluder or felt under each foot.

If you happen to have some bubble wrap lying around it would be worth a try.  Lots of Amazon goods come in bubble wrap envelopes.

One thing. If you have bottom air vents don't block them with something . Make sure the clearance stays the same or increases.

Look for something like this as a replacement for the existing feet on the PC. Much neater than a mat.

I'd recommend a barry mount. They make a million styles and sizes. Vibration reduction is what they are designed for. In the old days, you could buy them at any music store. I have some somewhere that I used under my turntable to minimize feedback from my speakers.

Rubber feet or bumpers. Minimizes contact, so less transfer.

Never heard of these before, very cool.   Thanks for the tip!

I use round rubber coasters under my sound bars. They stop the vibrations and they are cheap.

On amazon do a search for "shock absorbing pads" and many styles will be found.  Pick one that suits you.

Thanks for your reply.

Yes, I thought about piecing off a small section, or one for each foot, of a gym or yoga mat but I don't have an old one of those lying around.

While searching I saw the anti vibration pads for washing machines and that certainly seems like overkill on several levels even if they would fit.

No, it's not the fans. It's a WD Black HDD that periodically spins up and then spins down again a while later when it goes back to sleep.

Overall the PC itself is very quiet. It's just that WD HDD that's sending out a subtle low level hum through the feet of the case when it's spinning. It's like low frequency tinnitus.

Yes, this basically is what I have been looking for, hoping I had something lying around here that I could repurpose that way but no such luck. It doesn't hurt to ping others for ideas I haven't thought of.

Funny, for kicks I tried cutting up one of those white Amazon bubble wrap envelopes for a temporary solution but that was too thin. Esthetics prevented me from adding layers . . .

I had seen those and others that are very similar. They come very close but I prefer not to use anything that has adhesive. It also seems, through my searching, that when I factor in the particular item of something like this that I need to support the weight of my case they are out of stock or quite expensive. This may be a temporary supply chain issue like with lots of other tech products.

Yes, I have spent way too much time doing that. Unfortunately anything I have found so far that looks like it could be what I am looking for is out of stock, too expensive, or requires buying way more than I would use.
