« Very quiet, very low airflow »

As other reviewers have mentioned, the cables are kinda a pain. I had to buy splitters and converters in order to plug in a few of these to my power supply. They run incredibly quiet, but when you put your hand next to them, you can barely feel air moving away from the fan. I recommend this if you are just looking for a lot of 120mm fans that are quiet. I wouldn't recommend them if you're looking to really cool down your computer.

« Very silent but not much airflow »

This value pack is the cheapest thing you can get, with good performance. It is very silent even at max speed, and cools decently.
This fan has a 3-pin connector, so you might want to get a 3-pin to molex or 3-pin to 4-pin adaptor, since those are not included.
I installed 2 of these for my Antec Nine Hundred fan, and these fans are cooler than the original fans that came with the case.
Recommended to anyone that needs sleeve bearing case fans.
NOTE:
Since these fans are sleeve bearing, it is not recommended to install this fan horizontally, otherwise you will get shorter life and more noise.

« A real good deal for 4 quiet fans »

Pros: The one that I have installed so far is nice and quiet. 44 CFM moves enough air around while keeping it at 19 dBA, and it comes with enough screws for all 4 fans (the specs. say 4 screws but it comes with 4 packs of 4 screws each).

Cons: A little longer cables would have been nice, but can't take anything off since I knew what I was getting when ordering.

It's a good deal on some good fans. Would recommend. Should have ordered the 3 pin splitter as recommended in another review, I'll see if I can pick one up tomorrow so I can install another one of the fans and have more cable length.

« It works on a consumer PC »

I installed one of this in an off the shelf PC (not in a build yourself PC). I put it right in front of case vents using wires.

My computer used to run really loud. After installing it, it isn't loud at all. I had to use an adapter that connects from 4 pin power source to 3 pin. It was a bit of a hassle because it the adapter cables were set up backwards, so I had to switch them. Now that I plugged it in it works fine.

« you can't get a better deal than this »

I originally found an entry on an unnamed "deals of the day" website that had a competing site selling 2 Scythe S-FLEX (E-Series) fans for $20. I heard they (Scythe fans) were some of the best fans out there, and was about to spring for that deal... but when I realized after the added 8 dollars for shipping, it came out to be about 30 dollars... 15 bucks per fan. not so much of a bargain anymore. some fellow in that thread mentioned that if you want a real bargain, get these puppies from Amazon. Four 120mm fans for just over 10 dollars. Of course I had to take a look, and I'm glad I did.

Now, when I built my computer, I bought a CoolerMaster case (CM690). This case has room for 7 case fans I believe. It came with three of these very same model fans, so I already knew from personal experience that they were very quiet and did the job. Certainly worth 3 dollars a fan, no doubt; plus I wanted to add some extra fans since I had so many available mount areas in the case and the daily temps are in the upper 90's right now.

Ordered them, got exactly what you see in the picture. It's been said before, it's only 4 fans, and 12 screws for mounting. The fans are three pin. In my case, I have areas for 7 fans, but my board only has 3 headers! So I feel a lot of you are going to have to either get a couple of 3-pin splitters or something for these to use them all.

The fan cords themselves are approximately 12" long. My front fan cord will not reach any of the fan headers on my motherboard, so I had to use the dreaded 4-pin molex adapter /slash/ monstrosity that turns your tidy cable management into a rat's nest. I would really recommend something like this -- http://www.amazon.com/1FT-TX3-Power-Splitter-Cable/dp/B002DY7M1G/ref=sr_1_1?ie=UTF8&s=electronics&qid=1277947201&sr=8-1

That will allow you to hook up 2 of these fans into only 1 motherboard fan header -- plus, it gives you an extra 12" of cord. With 24" of cable (including the fan's cable itself), it should reach to the darkest corners of any sized case, and will be a lot more manageable and cleaner looking than the hideous molex/4-pin adapters.

So how about the noise? What can we compare it to in real life? Ok -- right now, in my case (1 foot from me, at about shoulder level) I have 6 of these fans running, plus the CPU fan. I would most closely compare the noise level to that of an air vent or air conditioner intake when your central AC is on. Just a very low, non-distracting flowing air noise.

Now if I get crazy and crank them to wide open, they are a bit noiser, but really not too unbearable. I would compare 6 of them at full speed to the noise level of maybe... an electric toothbrush? This is a bit distracting, as it actually catches my attention (as said though, the case is 1 foot from me, nearly level with my shoulders/head).

If you let the motherboard control the speed of the fans, they are very near silent. It sounds like maybe a newer CD-ROM drive steadily spinning a CD at idle (*not* revving up).

So if you are even questioning getting this... just spring for it. They may not be super high-end wind tunnel 250CFM fans that will allow you to use your computer case as a second freezer, but they do the job, and they do it well for such a tiny amount of money. On a side note, I recommend CoolerMaster products in general... especially their cases. Sturdy and well thought-out designs.

P.S. -- fan direction and airflow is sometimes a science, depending on where your mount holes are and what kind of heatsink, etc, you have. Personally, this is my config:

1 front fan pulls air into the case, over the hard drive bay area
1 back fan, obviously pushes hot air out the back
2 top mounted fans, with air flowing upwards and out of the case (my thought behind this was hot air rises, so at the top of the case is most likely going to be hot air that I want to remove from the case, not blow it back in)
2 side mounted fans (this one is tricky, as one is over the add-in card area... which I have pulling in cool air -- and the real question is: what about the fan mount right above the heatsink? I'm using the Intel stock heatsink & fan, which blows air straight up off the processor, which would be perpendicular to the side of the case. my thought here was at this mount area, have the fan blowing air *out* of the case, since hot air is going to blow off of the heatsink, into this fan, which will expel the air out the side of the case)

Point is, though: When you start working with 4, 5, 6 or more fans... you're creating areas of high and low pressure, which can make the heat move differently than you might expect. Some configurations that I expected would dramatically reduce case temps in fact did the opposite and raised my temps!

The only things I wish these fans had but don't are 1) shielded/covered cables. looks a lot nicer when the three yellow, red and black cables are wrapped in a black shielding. I imagine this could be done with some duct tape after you got your cables routing where you want, so it's not a big deal... and 2) maybe if the cables were a little bit longer... like maybe 18" would be great, for larger cases. It gets annoying having to reach in and unplug the side fans every time I want to take the side cover off! Other than that, this pack is the cat's pajamas.
