Pros
Blows a lot of air, great colour
Cons
Little on the noisey side but not bad. Fan leads are way too short. Keep in mind they won't reach front to back of case.
Summary
Great fans, would buy again, they keep everything nice and cool

Pros
Very bright (brighter than the red or blue version)
Cons
still has the same sound signature as the other sickle flow fans - a bit noisier than most
Summary
I had a few dozen of the red and blue version which I used for other people's builds. They are not the best in terms of being silent but they do offer a significantly better airflow compared to generic LED fans.

I have yet to fault the quality of these fans they seem to last long enough to warrant the cheap price (when on sale). These are not my first choice for fans (I'm not really a fan of LED fans) but for my friends who ask me to build LED lit systems, these are a good compromise between price, noise level and air flow. I did a recent build with 2 blue LED fans and green LED strips and they didn't look right. The person who owns the system is happy with the color, but I'm a little bit OC when it comes to these things so I ended up replacing and matching the overall lighting.

If you do not mind the slightly higher noise levels, then these are excellent fans. They should be paired with speed or voltage controllers but they will obviously loose a little brightness when voltage is limited.

Pros
- Surprisingly good airflow power
- very inexpensive
- LED output is very bright
Cons
- n/a
Summary
Got 3 of these ones running in my system. Airflow-wise its great considering they're not very expensive, highly recommended if you don't want to spend 4x the amount on a different brand.

Pros
amazing price, high rpm, Bright led
Cons
bearing on the fan
Summary
Really bright among blue and red. I have all 3 colours and green stands out . the least bright one is red.

Now I will explain the con, the bearing on the fan needs to be lubed or it will make squeaky sounds in the long run especially running at low RPMs. The sound is annoying and sharp so just to give guys a heads up, but at this $ you guys shouldn’t complain much lol.

Pros
Great performace relative to price.
Cons
Not the quietest fans on the market.
Summary
Perform well and can push air. It's not the quietest fan, and there are other fans on the market that can perform better. However, for its price, it is a good buy and I would recommend it to others and am willing to buy it again.

Pros
Inexpensive
Bright
Cons
Cheaply constructed
Low static pressue
Summary
I bought 6 of these fans to go into a new build of mine. Only 3ish weeks of use later and 1 fan is "broken" and one blade hits the cowling and another squeaks loudly. I have had to remove both of them and replace them with the stock fans included with my case. Also the molex to fan power converters are so difficult to attatch to a molex cable i broke 2 of the cables that came with my PSU just trying to connect them, before I discovered that I had some old ones in a box that fit perfectly. If you get fans that do not die they are very nice but 2 out of 6 fans with an issue is unacceptable to me. I am going to look into buying some corsair high SP fans to replace them for the long run.

Pros
Good airflow. Nice LED glow; not too bright. Potential to be quite quiet.
Cons
Can be loud depending on where and how it is mounted.
Summary
I like the LED look of this fan, and I love its airflow. This fan moves a lot of air, and its native fan noise (standalone/outside of a case) is quiet. However, when mounted as an intake directly on a some types of mesh, the air noise will be pretty audible. I had two mounted to the front of a Cooler Master HAF 912 and at full speed the two together were as loud as two full-power Bgears b-blaster 120mm fans on the top exhaust mounts but with a slightly higher pitched air whine. It didn't bother me personally, but this just shows that this fan isn't always as "silent" as Cooler Master markets it to be. Still a great fan for the price though.
