Review: 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 desertcart. 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.desertcart.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.
Review: Compre dos ventiladores para un gabinete y son muy silenciosos comparados a los genericos o de marcas mas economicos, no zumban nada y los tornillos de montaje permiten una instalacion firme sin juego para que no vibren, los recomiendo mucho ademas de que son de buen precio, son de una marca reconocida. Vienen con conector de tres pines para tarjeta madre y con un adaptador para molex de cuatro pines.

## Questions & Answers

**Q: what adapter do i need to connect these to my power supply? and can i connect all on the single cable**
A: I purchased the 140 mm, though I would assume they should be the same. the fans themselves are 3 pin if you are going to attach them directly to your motherboard but they also come with 3 pin to molex adapters (which I used) in order to connect them directly to the power supply. I was able to attach two fans in series to one of my power supplies molex strips.

**Q: what is the cfm**
A: 24.2CFM

Ripped from their website. 

Standard fan 80mm

Recommended for CM 690.

24.2 CFM Higher airflow to enhance cooling performance.

Silent operation at 20 dB-A for excellent case cooling.

RoHS compliance for protecting the environment.

**Q: I would like to use this fan to help cool a rv fridge. which two wires should I use to connect it ?**
A: 2 thin fans 80×80×15mm or 120×120×15mm use in front of RV refrigerator fins it will take this cooler temperature move it faster throughout  the refrigerator will keep cool.

Use Inkbird Dual Stage DV 12V Digital Temperature Controller Fahrenheit Thermostat Heating and Cooling for Homebrewing Brew Fermenter Fridge Incubator Greenhouse

**Q: Is the 92mm size a measure of the physical plastic, so that it's 90mm from screw to screw?**
A: The size is the actual outside measurements of the housing. A 92mm fan has holes on 82.5mm centers and a 120 mm fan has holes on 105mm centers. I have a Thermaltake case with room for a 120mm fan, but the widest holes are on around 93mm centers that don't fit any readily available fan that I have found except these. My 120mm version of these has a second set of holes on the output side on about 93mm centers that work in this case. I stocked up while they are available.

I have bought quite a few of these fans over the years (not all from Amazon mind you). They are a good fan, at a fair price. The noise level is reasonably low for the price, but you'll still hear them if you've got 8 of them running in your PC like I do. If you want something quieter you're looking at BIG BIG MONEY per fan. These last years usually 24/7.
