Cons: Cheaply constructedLow static pressue
Pros: InexpensiveBright Comment:
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. |

Cons: Can be loud depending on where and how it is mounted.
Pros: Good airflow. Nice LED glow; not too bright. Potential to be quite quiet. Comment:
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. |

Cons: quite noisy
Pros: sucks a lot of air Comment:
I got this for my Antec 300 since it doesn't come with a side or front fan. At 2000rpm it sucks a lot of air in, but in turn it's quite loud. |

Pros: Fan is awesome. Great value for performance. Comment:
LED's are great, moves more then enough air. Purchased 2 of these, and 2 140mm green led bitfenix and these are by far better at their job. For less then $10... would most definitely recommend! |

Cons: Tad noisy, but that's to be expected
Pros: LED is quite impressive and pronouncedComes with molex adaptersVery powerful, lots of airflow Comment:
These surprised me how good they actually are, I'm not a huge coolermaster fan (pun) but my customer wanted green in his case, and the price was certainly right. The sickle design really moves a lot of air, free standing they'd push themselves across my desk. Put in 3 of these and his case is so cool I want to store beer in there. Lights are very bright, nice colors. They're not quiet, but that's to be expected with that kind of performance, I wouldn't call them "loud" though. |

Cons: -On my old Thermaltake V4, it was unbearably loud. On my new NZXT Phantom, it is quiet, even on 100% fan speed.
Pros: -Pushes a LOT of air-Nice build quality Comment:
I purchased this fan 2 months ago, and put it in my Thermaltake V4 case. However, it was unbearably loud. I tried putting it on the front (intake), side (intake), and top (exhaust), and in each configuration, it was extremely loud at 100% fan speed. I did not have a fan controller at the time.I now own an NZXT phantom with a built-in fan controller. At low speeds, the fans push an acceptable amount of air, and are near silent.On full blast, the fans do not produce such an intrusive sound as was found on the Thermaltake V4. This is most likely due to the NZXT's sound damping.I recommend this fan to anyone who has a fan controller. |

Cons: None.
Pros: Works, bright green LED looks nice in case. Comment:
After 1+ week of use, has worked perfectly so far. Installation was simple. Comes with 4 case screws, but I used the ones that came with my case. |

Cons: Ive got 2 outside my case and im scared i might put my toe in the vent.
Pros: Cheaper than the non LED ones...wtf? Comment:
I bought 2 of these about an hour ago they were easy to install however when i went to plug the first one in i goofed and almost broke the power connector, even if i did there was a secondary one so i wasnt worryed.Other than that. Great bang for your buck |

Cons: - The LED isn't very bright, for people who want their case to really shine- It's a bit loud to my liking at high rpms
Pros: - Cheap- Can be partially controlled from the motherboard- Airflow seems pretty good at higher rpms Comment:
Nice fan, not too flashy. I'm not actually a big fan of LEDs, but for an odd reason, plain fans cost more than LED ones. I installed this one in the back of my HAF 912 and it's currently inaudible. |

Cons: None
Pros: Good price Good airflow Comment:
Got this for 5$ each which is a great price. It has good airflow and isn't that loud. I'm using it on my H70 and it's much quieter than the stock fans. Definitely worth the investment if you need cheap fans and it's on sale regularly too. |
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.
