SilverStone Technology EPDM Sound Dampening Foam/ Noise Absorption Material Excellent Adhesion In High Heat 2 Pack SF01-NEW

Nice medium to low density, soft foam. Very sticky backing. Easy to cut with scissors. Simple packaging so I don't feel like I'm killing baby seals by buying it.This big 2 piece pack is plenty of material for an entire case at a good price. Even enough for my huge Air 540 I was able to get all major panels (I put it right over the window, too) and put strips in all the other flat, non-perforated areas on my case large than about 1"x2". I still have a piece left over (about 1/5 of one panel) and really have no where else to put more down without interfering with side panel installation or covering up vents.I don't have an SPL meter but it definitely seems to help a bit with noise. Fairly minor, and it's more important to buy premium low noise fans and low noise video cards and CPU heatsinks, but this is a good tweak for those trying to take an extra step.

This costs and works as it should. You get a decent amount of acoustic foam for what you pay for and it does absorb sound. I have tested it with my new PC build and the fan blowing is more muffled with it than without it. One caution, the backing of the product is conveniently sticky for application to a PC case so be CAREFUL when applying it. If this product sticks to itself, it will NOT un-stick. I ruined a sheet this way and had to order more, very frustrating. When applying, peel back a bit of paper, stick it on one end of the case wall, and peel the paper back as you stick it across the case. You may also get air pockets but these can be avoided with careful application.

I used the SilverStone foam to quiet a noisy computer tower. It was pretty easy to use, cutting to size with an exacto knife and ruler. The foam is lighter weight and softer than I would have expected. The adhesive is quite strong so you will NOT be able to remove and reposition it once you stick it down. Fold back a little of the non-stick cover, stick that edge in position, and then gradually peel the rest of the non-stick from between the foam and your surface, sticking as you go. The foam is soft and quite easily stretched, so you must be gentle and slow or you will pull the foam out of shape resulting in wrinkles and/or a poor fit.I applied the foam to as much of the inside surfaces of the computer as I could without removing any parts or the motherboard. The computer is much quieter now, but by no means silent. A lot of the higher pitched fan and drive noise was eliminated. The sound now seems to be mostly "whooshing" air and is much less annoying though still quite audible.This computer had an intermittent vibration on the main removable side panel, which I could always stop just by holding a finger against the side of the machine. However, keeping one hand on the case did slow down my typing considerably! I tried different solutions using tape and inserting paper shims in the seams but nothing really stopped that vibration. With the SilverStone foam it is now completely gone - that's a big improvement!It's possible that  DYNAMAT 10415  would have been even better - but it just seemed a little pricey to me at $19 for 200 square inches vs. 630 square inches of SilverStone for $14. It's my non-scientific impression that DynaMat is more about dampening vibrations in metal surfaces and less about absorbing ambient sound. The SilverStone actually cured my particular vibration issue and does a good job on absorbing noise, especially the more annoying higher frequency sounds. I'm happy with my purchase and the results.

I was actually really surprised with how big the pads were, they came in a 2x EATX size, able to cover a huge panel. I cut mine up to fit my case and it got rid some of the rattling noise that was annoying me, I only used 1 piece for my ATX size case (with a window). It's very very sticky once you put it on taking it off can be difficult and rip apart the pad. It's not magic foam, and definitely won't do much if you have a windowed case like me, but it will get rid of extra noise.

Had a noisy NAS Enclosure (4 hard drives constantly clicking away). I cut strips of these and placed them inside the enclosure in areas that didn't block airflow, didn't even need to use that much either. It is now super silent and I'm very satisfied. I've had previous experience working with sound dampening foam so this worked exactly how I wanted it to.Pro Tip: use a new / sharp blade when cutting foam of any kind for clean edges, otherwise it will pill up and get messy. Use this advice for sound dampening foam, foamcore, styrofoam, etc.

While I was replacing a bathroom exhaust fan, I wanted to add some sound dampening to what is basically metal cone surrounding the fan. It is the cheaper choice than it ripping out the unit and buying a new quieter fan.

I struggled to decide what score to give this. On one hand it worked to some degree. On the other hand, I regret purchasing it. But since that regret is partially my fault I ended up on 3. First and foremost the question is, does it work? Sort of. On a scale of 1 to 10 with 1 being silent, 10 being a jet engine and 5 being audible but not really distracting, my PC was about a 5. I would say at best it's a 4 now. Basically the only noise generation is fans. I have no mechanical hard drives, no optical drives and not water cooling pumps or anything. All I have is a 3 good fans. One corsair "silent" on the front, one on the back, and a good cougar fan on a decent CPU cooler. Then I have the power supply fan, and video card fans. It made very little difference adding the foam. On top of that, it was a pain to install and it's basically permanent. my side panel didn't close right, so I had to "peel" some away to get that right and now it looks terrible. If I was doing it all over again, I would have just spent the extra money on a case with built in sound dampening. So it did work to a small degree, but I still don't think it's a worthwhile product. If you are at the point where you are close to silent and need something extra to push you over the edge, maybe. But for me, it barely made a difference and my temps are now 1 to 2 degrees (obviously not a big deal but still worth mentioning) higher.

I used this to dampen the sound in the case as well as between the PCB and base of my RK84 keyboard. It took some time to cut the smaller strips to go between the switch sockets holes on the metal base but there was so much material that even if you screwed up it was easy to just make a new piece without worrying about running out.The adhesive works well, and if you need to pull off from the frame there isn't any adhesive residue left over when you do. The material is easy to cut with scissors but NOT with a pen/precision hobby knife. When I tried to cut it that way it started to serrate the foam rather than just cutting it through. There might be better luck with a razor blade which is much thinner and sharper but I didn't want to take the risk and the scissors were able to do the job fine for cutting into the strips.It's not as elegant as buying a pre-fabbed foam board and takes longer, but this is much cheaper does the job of sound dampening well and you have enough material left over to do at least 5-7 keyboards with excess material.

I bought this to help reduce the coil whine on my graphics card, reduce the noise from my watercooling pump and overall fan noise. I'm very impressed with how this works. The coil wine and pump noise is pretty much gone and my overall fan noise has decreased. I would definitely recommend this product.

Purchased this foam to install into a Fractal Design Core 1500 case being used as an unRAID media server. Although a bit tight with this particular case, the foam is easy to cut and position and provides just the acoustic dampening needed for a quiet living room.

Excellent dampening foam for keyboards. It is thin enough to fit into most keyboards and the foam itself is soft enough that you can really squeeze it into cases. The adhesive is super strong and can leave residue. So, install the foam carefully into the case before it gets to hard to reposition it. To note, there is a lot of foam. I would say that you can probably cover over 7-8 TKL keyboards with how much material there is.Highly recommended for people who are looking to mod their keyboards!

This is my review on the product. The item was soft and a little thin. That's about it.My item was handled incorrectly and it was shown on photos. I have a bunch of orders and put it a one big box.They could easily not folded the item. Made my item look bad quality. I returned it and told amazon what they did.
