Cons: -Kind of loud
Pros: -good cooling-cool LED-Cheap |

Rating: Review Date: 05/30/12 |
Cons: - The fan is louder than I expected, although, it's not from the fan itself, but rather the stream of air that is passing through it and the fan filters I have placed- Low static pressure not recommended for cooling a radiator.
Pros: - Cool fan design, functional.- BLUE LED- Long-life (if the claim is true)- GREAT CFM rating as a case fan. Comment:
The best fan for certain applications if you know what you're doing.I purchased 4 of these on sale for $5/each.. my whole computer sounds like a wind tunnel (not a vacuum though). Will purchase a fan controller to turn it down/up when necessary. |

Pros: Silent, WOW they move air!!! Comment:
They blue led isn't annoying, but I didn't care abourt it. Got two of those because they were cheap. One is my rear exhaust and the other I added has the pull fan on my CollerMaster 212 heatsink. They're both great and they move lots of air! I got some coolermaster 1376RPM silent fans for front intake and side exhaust of my case and I think they're looder, so I should've bought 4 of the 2000RPM fans... any I have a good airflow at the moment so I'll leave it like that! |

Cons:
Louder than advertisedDifferent colors on LEDHard to install
Pros: Decent Air movementSleek design Comment:
I originally bought two of these to replace two stock fans in my NZXT case because I thought they were loud. Basically they move the same amount of air, and are a little quieter, but not enough to justify replacing my old ones.Then, on one of the fans three of the LED lights are a teal color and the other one is a true blue. It makes fun one ugly looking fan. |

Cons:
-Noise-Cheap plastic frame-Not so sure about the durability of the fan due to its cheapness
Pros: - Push a lot of air- Cute blue (useless?) LED- Cheap price Comment:
I bought 4 of theses $4.95 with the price match. I put one on the side of my tower, but the sound of the vibration was way to disturbing, so I had to remove it. Althought, it moves A LOT of air. It's not that quiet, but you get what you pay for. It doesen't sound like an airplane eider, but depending of the case you have, it can be noisy.I think next time I will pay a little more to have a less cheap and noisy fan. But if you don't mind for the noise or the cheap plastic frame, go get it. |

Cons:
-Specs are an outright lie, its not that silent and it doesn't move as much air
Pros: -Cheap-Blue LED Comment:
Bought two and while they did work, they were a little too loud for my tastes. These should work great for any regular build though. |

a bit loud at max rpm, need to tune it down with controller.screws are very hard to install at first, as with most new fans.
Pros: cheap, nice led. Comment:

Pros: cool lighting Comment:
I have many other fans, and these are no where near 60cfm, same goes with 19dba.I have 19bda fans, these are way louder. |

Cons:
-is not 19 dba-actually only have a pressure of less than 1.5 mmH20 despite is miraculous claims of 3 mmH20 (its weaker than my GELID fans).
Pros: -Cheap-Has Blue LEDs-Decent amount of airflow Comment:
If you plan to put a filter infront of it, don't bet on it moving any decent amount of air. The 3 mmH20 claim is bogus and same with the 19 dba. I have GELID fans that claim to be 1.5 mmH20 and 24 dba and still pushes more air through the filter at a much quieter dba. |

Pros: Looks great, high airflow, very silent Comment:
These like most other Corsair fans are silent running fans but push alot of air. I wish NCIX would carry more of their fans like the 200mm fans, because all Corsair products seem to be of high quality and have great warrentys as well. |

Pros: LEDs are bright, but not to brightPush LOTS of airQuiet Comment:
I replaced my the fans that came with my case (also Coolermaster fans) with these. They're pushing lots of air, and they're incredibly quiet about doing it. No regrets buying these. |

Pros: Cheap, High Air Flow, Low Noise Comment:
I bought both Blue and Green version. Moves a lot of air. LED is decent. The best thing about this fan is that it is quiet. I had Scythe 3000RPM fans that were soo loud even with a fan controller. This however on maximum speed, is very quiet. I have 6 fans in total, and you cant barely hear any noise. |

Pros: Replaced my Scythe 120mm for this one. Gives about 75% bluish hue w/c is not too harsh on the eyes, looks good on a windowed case. Comment:
Gives off a good enough cooling, not too windy if that's what you want to know, but it is rather quiet w/c is a good thing. Comes with 3/4 pin too. |

Cons:
Price can be matched to be much lower
Pros: Quiet (though I'm it's no different than any other fan with the same rpm and cfm) Comment:
I bought both the green and blue version, and the green version of this fan actually has a higher CFM rating h 90 as opposed to 69. However, seeing as they are the same I think this is a typo (the sticker also says 69). Also, the price can be matched to be much lower. They work as well as any other 120mm fan, just be sure to compare their CFM and RPM and anything else that matters to you. |

Pros: Great Fan. Keeps system cool. looks awesome. Good price. Comment:
The Coolermaster R4-L2R-20AC 120MM Blue LED Case Fan is a great little fan. I bought it to replace a side fan in my custom built gaming desktop. It keeps my system cool and looks wicked awesome in the dark. The LEDs are wicked. |

Cons:
A little noisy at full duty cycle but not ridiculous -- not enough to take an egg away.
Pros: Matches the Storm Sniper case perfectly. LEDs are not blinding and match the LEDs used by the other CM Storm Sniper fans. Comment:
I use this to replace the stock rear 120mm fan on my CM Storm Sniper Black. Significant increase in exhaust CFMs. This fan doesn't have dual power for LED's and duty cycle for operation via the CM Storm's fan controller. Not an issue; however, because I don't ever run my case with LEDs off. |
These are good fans at a good price. my only problem with them is that they are a bit loud.
