Pros: quiet and efficient.

Cons: none so far.

Other Thoughts: I would recommend for people on a budget needing a silent fan.

Pros: Silent. Build quality.

Works!

Cons: None

Pros: -Silent
-Look good
-Efficient

Cons: -Only 3 Prong

Other Thoughts: I would recommend to anyone needing this size of fan. My computer doesn't have coil whine or any fan noise. All I hear is the air flowing out of my case.

Pros: -Very quite compared to my old case fans
-Air flow is great for the price
- I have a GTX 480 in my rig and if it keeps this card cool, they will keep anything cool.

Cons: - None to be seen.

Other Thoughts: -Fans quietly hum while on. (Not a bad thing just a noise level idea for the product)

Pros: Seem to push a bit of air. VERY quiet, which is what I was aiming for. Comes with rubber screws; I already snapped one but it lasted through 3 re-mounts while I was trying to get the cord position right, and I wasn't exactly light-handed about putting them through the fan holes (ug), so I'd say they're pretty good quality screws.

Cons: None that I can think of for the $10 I paid for each one.

Other Thoughts: I guess these being 1200rpm that I can only ask for so much airflow, so I won't complain much about it not feeling like a hard jet like with the 70-cfm Cooler Master ones (my usual go-to when not worried about noise), which I thought were quiet before trying these things. Then again, these are ridiculously more quiet, and using a 65W TPD i5 and plugging a GTX970 into my rig in the future, 3 of these on intake will definitely do the trick. I'd definitely recommend them whenever they're on sale.

Pros: Does its job and is very quiet

Cons: None

Pros: Very quite fan move good amount if air
Unit ship right away could not be happier
great choice

Cons: none

Pros: I love these fans! I have bought 4! 2 for my PC and 2 for my friends. His PC went from sounding like a jet engine to something more silent. My PC is dang near silent as well!

Cons: None so far!

Pros: Very quiet, inexpensive

Cons: Questionable durability

Other Thoughts: Bought this fan just over 2 years ago to match up with the other 2 Fractal Design fans that came with the case I bought at the same time. I was so impressed with how quiet they were that I wanted my third fan to be exactly the same. Unfortunately it began to fail a few weeks ago, it began to vibrate and make a hellacious noise. Scared the hell out of me too because at first I thought it was a hard drive failure. A blast from a can of compressed air would get it to stop making noise but the frequency I was needing to do this has been increasing so I opted to replace it.

This is the first case fan I have ever had that has failed. I assume the bearing is failing/failed, it's in a PC that is on daily but not round the clock so kind of surprised by it. The other 2 fans are still working well so I'm hoping that it's just the one that may have been a bad apple out of the bunch.

Pros: I am very pleased with this fan. It seems very well made and sells for a reasonable price, It comes with rubber studs to isolate it from the case but I did not find them necessary. It also comes with a voltage reduction cable but I am not using that either.

Cons: At full RPM it does make a little noise but no fan is going to be completely silent. Barely worth mentioning.

Other Thoughts: I mounted it in the bottom front of the case, drawing air in. I recommend this fan,
