Pros: I find that as soon as I have received the Silverstone foam that I will let it air out for at least 8 hours before I begin to apply the foam to the inside of my computer. I want everyone to know that before I purchased the foam that I knew it would not completely silence my computer from the noise of the fans inside of the computer. I have a high end computer with 11 Noctua industrial fans that all of the fans will go above the 2000 rpm range so the noise is heard. The foam will keep from being louder because I have noticed the sound is not as loud but will still be loud enough. I have just installed since a day ago so I will have to test how well the temps are inside of my computer later on. I want to run the computer for a long period of time before I start to see what my temps will be. The foam was easy to install and I was able to reapply the foam when I improperly installed it. I was very impressed of the way the foam applied to the inside of my computer case and does not distract from the appearance and since I have a glass window that is tinted enough to show only the RGB effects inside of my case than I am very pleased the foam has not interfere with the looks.

Cons: No cons at this time.

Overall Review: I would recommend this foam product from Silverstone but beware of whether or not you will have a lot of fans in your case and how loud they are due to the RPM's and the db's that the fans will put out to give either a more silent case or if you will still have noise depending on the fans output. I would suggest to anyone to do your research and read the reviews and make up your mind whether or not it would help you. I would buy the foam again to do my other computers. Great product and for me every little bit helps in controlling the amount of noise from the computer.

Pros: -Completely got rid of my coil whine!
-No bad smell like others have reported
-Enough to line my whole case

Cons: -none for my situation

Overall Review: Bought this for my HTPC with a GTX 1050 that had a very high pitched whine when playing videos. I sit about 10 feet back and the whine was very annoying in quiet movie scenes. Figured I would give this product a shot before swapping components. TBH I had no idea if it would make any difference. I was shocked when the whine was completely gone! To be fair, it did not seem to make any difference to lower pitched fan noises.
In conclusion, I'm very happy with the purchase but I think a lot people are using this product with the expectation of silencing noisy fans and are disappointed. From my experience, this will absorb very high pitched noises but not do much for standard fan noise.

Pros: -Inexpensive
-Multipurpose

Cons: -None really; assuming I'd used it as a sound dampening foam, I might have a valid review here

Overall Review: -Bought product to use as makeshift grommets for my case as it doesn't have any; worked fairly well, but not as well as I wished (right tool for the right job)

Pros: 2 larges sheets enough for a medium case.
The adhesive is really strong it wont peel away easily.

Cons: Doesn't help that much , it's actually really thin.
Smell bad too.

Overall Review: I can't tell if it really help.

Pros: -Way bigger than I expected OR will likely ever use
-Meaning BUY ONE AND YOU'RE SET! For $16 bucks w/ shipping, what a deal!
-Easy to cut & adhesive BEFORE BEING PRESSED allows for moving and repositioning. HOWEVER, once you press it down any surface IT IS DONE! Or a messy peel awaits you.

Cons: -I wish it was thinker, like 6mm+ DESPITE being effective as is.
-Material does feel cheap, if you try to peel the actual foam comes off sometimes. That is the cost for being affordable, HOWEVER it does look cheap.
-Best fit for the side-panel holding the cables in mid-towers+ OR covering sidepanels that are open for noise lowering, as I did

Overall Review: Used on my Corsair 250D side panel - although I bought another panel just in case I f*ed this up or it sucked.
Lowered noise significantly, and because I can cut it I can fit it many places. Used only 1 of the 2 sheets that came for my mini-itx case, and there is still PLENTY left.

Pros: I mean, I think it works. It probably does. I didn't gauge a before and after very scientifically. Then again. I also installed this at the same time I replaced a stock AMD CPU cooler (was that thing loud // 6500 rpm) so it's hard to do a before-and-after comparison.

Crammed it onto any flat surface inside the case as well as the shroud that covers the intake fans (doesn't block airflow at all).

Either way, it installs nicely. Very easy to work with as long as you're not a tool. I had some leftover so I put it to the underside of my keyboard, so it's not as clanky against the desk. Definitely works there.

Cons: I just wish my PC case didn't have such a big window, or else I'd have used all of the two sheets. Nevermind, I bought the case because of the window.

Pros: I purchased this foam over 6 years ago for use in my Silverstone Raven case. The foam comes in two large sheets that can easily be cut to fit any space. The adhesive is very strong and has not come loose in over 6 years. The foam also does not seem to collect dust.
I have this on both side panels of my case (I cut it to fit around the case window). I also used it under/around the power supply.
I find it helps reduce vibrations for my fans as well as cables in the back of my case. As my case has lots of vents, it doesn’t do much for dampening the sound of fans (in my situation).

Cons: Can be a little tricky to mount over a large surface. Go slow so you don't get bubbles.

Overall Review: I recently purchased an In Win 303 case and bought more of the foam for that case. The foam I just recently purchased is the same thickness and quality as the 6 year old version, although, the price has almost doubled from 6 years ago. I will always buy this product for my new computer cases.

Pros: sticks well, thin but absorbs sounds and vibrations

Cons: none

Overall Review: As long as you're not the kind of idiot who uses it to cover up exhausts and layers the stuff right around hot components it works great with no side effects. I used it on the back wall, around the window on the front, used it to seal around the 360 rad in the top of my case. Made a huge noise difference and no different to thermals.
