-Great airflow
-Green light

Experience: 2 Months

Very bright green
Always on sale
Not too loud
Is an intake (Brings air in from front making other side ugly as an exhaust fan unless it's going to be looked at from a side window standpoint, then it looks good)
Buy it if you're looking for a good green fan with low dba. Looks great in windowed cases. Never buy if over $10, will go on sale

Blows a lot of air, great colour
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.
Great fans, would buy again, they keep everything nice and cool

Very bright (brighter than the red or blue version)
still has the same sound signature as the other sickle flow fans - a bit noisier than most
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.

- Surprisingly good airflow power
- very inexpensive
- LED output is very bright
- n/a
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.

amazing price, high rpm, Bright led
bearing on the fan
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.

Experience: 2 Months
Make a box looks better!
Good Price
none so far
Use it to add fans to my box. Not too loud!

Experience: 1 Months
Great performace relative to price.
Not the quietest fans on the market.
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.

Experience: 24 Days

Cheaply constructed
Low static pressue
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.
