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: Cool, quiet and on budget. - First thing I would like to address in this review is, if any of these fans make any noise, they are defective. You buy from desertcart for a reason. Send it back and get working ones. desertcart has great service and will not charge you a penny for DOA s. I say this because there are several negative reviews claiming that the fans make too much noise, which isn't the case in a properly working fan. Now about the fans, they are so quiet, even at full power. You can't tell your computer is on without checking to see the power LED on your rig. They are less than $4.00 per fan. These are the same fans that came with my case, a Coolermaster HAF 812. I had six fans running and not even a hiss. They offer a nice balance of speed, volume of air, and silence costing at least 3 to 4 times as much. I have been experimenting with some of the more powerful fans available in the marketplace. The highly regarded Scythe fans push more air but at the expense of making noise. They are more costly, make more noise at a high enough speed to make a difference. Compared to the Scythe fans a Glidestream 140 and a Kaze Maru PWM 120mm, each costing the same as these four fans. The Cooler Masters win both on price and effectiveness. The only thing that these fans lack is PWM. The connector is 3 pin, and not 4. If your needs don't require PWM, I highly recommend these fans to anyone who is on a budget, or who appreciates the sounds of silence. ## Features - Higher air flow to enhance cooling performance. - Silent operation for case cooling. - Air flow - 32.53 CFM.

I have always loved their products. From power supplies to cases, heatsinks and fans, they do it right. These fans are also good and at the right price too. I needed more cooling for my HAF 912 and these just made too much sense. I already had a TT blue LED case fan on the front bottom but I still needed the side and top two fans, and this kit has been perfect for filling those holes. They aren't quite so silent though, and buzz particularly bad when mounted on the side of the HAF 912. The good thing is I needed extra fan headers so I paired these up with a Scythe Kaze Q 3.5" fan controller. I have them all turned pretty much all the way down and they still move air nicely and ARE quiet when turned down. I like the fact that the Kaze Q turned out to be 3.5" (I didn't look at the specs and was expecting 5.25") because I ended up leaving it inside the case. I was also able to switch from the TT blue's 'smartfan' controller to the Kaze Q and it has made that fan as quiet as the rest. Anyway, back to these fans, they're a great deal. If you need them to be truly 'silent' though, pair these up with a fan controller. My system is quieter AND cooler. Wow.
