You will simply not find more bang for your buck. These are quiet fans that last and they will plug right into your motherboard. Just FYI, you want to mount these fans vertically and not horizontally because they are sleeve bearing fans. I have made the mistake of mounting these fans horizontally and they get loud and die prematurely. This is not CoolerMaster's fault, it is simply the nature of sleeve bearing fans. For horizontal applications you can use fans with a ball bearing, a rifle bearing et al.

This is a great value. The fans are silent as advertised and they are packaged in a perfectly sized box.

One thing to keep in mind if buying these fans is that they use the 3-pin connectors. You may need to get 3-pin to 4-pin power connectors if you don't have any spots on your motherboard to connect these fans.
***4-PIN ADAPTERS ARE NOT INCLUDED.

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 used this fan to replace one in a CM Scout case that got noisy. Installation was a breeze (sorry) and took very little time. This fan is almost silent yet moves a lot of air.

Purchased these fans in order to cool down my AV cabinet. I linked all four with a thermo-cooler, so that I didn't have to turn them on or off manually. The system works great! Very pleased with the result and now I can leave our armoire closed when using the receiver or PS3.
Recommended if you are on a budget and don't mind a little DIY.

If you have a cheap case or mesh blocking the airflow of the fan you can forget about silent with these. Both of those factors will lead to vibration and/or a hair dryer-like sound from the fans. Cooler Master does not provide any rubber grommets or pads to damper vibration so be aware if silence is a priority for you.

Aside from that, they appear to be well built and I don't foresee them failing any time soon.

This video is from the JerryNeutron YouTube channel and provides an overview and sound test.

P.S. - I've moved the intake fan to the front of the case, underneath the faceplate and the noise level appears to have improved some.

works well with cooler master elite 341 case... these arent high performance but this should move a fair amount of air on a un-overclocked/un-modded pc.. provides enough ventilation and lower the temps a bit.....

These fans are an excellent deal!.
PROS:
- They provide excellent airflow and they fit in any mid to full tower cases. The speed is rated at +/- 1200 rpm which is fair enough for a basic to gaming system.
- All the screws are provided just be careful with the power since they have only 3 pin connectors and the 4-pin molex adapter is not included. So make sure to get the ones that you need. I have them inside a Cooler Master HAF 912 case.
- Try to build an airflow to suit your needs. Read this forum in Tom's hardaware for good airflow design, search for positive and negative and you will learn even more about case cooling.
- The shiny side is the intake whereas the side with the wire and the specs is the exhaust.

Hope this helps with your purchase and I recommend those fans for anyone that wants to have a good airflow design in your case.
