I have been buying S-Flex fans for 2 years now and I keep coming back for more. I have never had one die or start making strange sounds after being used for awhile and they work in any position I put them in. Highly reccomend these to anyone. |

Pros: * Moves Air Quietly Comment:
I have this fan as an intake on my side panel. It has been doing its job well and without incident... what more can one ask than that ?As for noise, it is by far the quietest fan in my case and I can't notice a different in overall volume with it running or off altogether. |

Cons: wires are not sleeved
Pros: - S-FDB bearing- 150,000 hrs mean time til failure Comment:
Most case fans use sleeve bearing which have very poor life span (1 to 3 yrs average) whereas this fuild bearing design has well over 10 yrs on the conservative side.drop the voltage down from 12v to say 7-10v and its nearly silent.This MadShrimps reveiw has all the details - http://www.madshrimps.be/?action=getarticle&number=1&artpage=1708&articID=421 |

Put 3 of these on my TFC 360 rad and they perform flawlessly. Alot of airflow and not very noticeable noise wise compared to other system fans. |

Cons: not sleeved
Pros: fairly quiet. I'm not going to tell you it is the most quiet fan you've ever hear but for a normal human, they are quiet silent. push enormous amount of air. Comment:
the cable length is pretty standard. would be nice to have it sleeved but... come with a 3pin to 4 pin adaptor |

Cons: -Noisy over 1000RPM
Pros: -Quality-Good bearing design-Good airflow/RPM Comment:
This is a great fan for high static pressure applications like mounting on heatsink or restrained front panel intakes. Takes undervolting like a champ and will be very quiet once it goes under 900RPM. |

Cons: None
Pros: QuietMoves lots of air for it's RPMGood static pressureGood price when on sale Comment:
I bought this on sale to replace an Tri-cool in my Antec P182 case. The top fan was making noises and now with the Scyth it's very quiet and pulls more air than the Tricool on low. |

Cons: - Noticeable high-pitched whine at full 12V
Pros: - Fluid Dynamic Bearings for long lifespan- Good CFM:dBA ratio Comment:
While there IS a noticeable whine at 12V, I rev it down to ~800 RPMs with a fan controller and it is nearly silent, yet still pushes a good amount of air.The use of fluid dynamic bearings is a plus as the expected lifespan is >150,000 hours! This fan will most likely outlive some other components in my PC.FYI I have this fan mounted horizontally on my Accelero S1 Rev2, which cools my 8800 GT. I have a 1st gen Antec Sonata case, which was designed for silence, not ventilation, so having this fan on the 8800GT+S1 definitely helps.Overall, a great high static pressure fan built with quality components and good air:noise ratio. |

Cons: -more expensive than some brands
Pros: -great price, great performance-quite silent even after a year Comment:
I bought these because of the sound and cfm ratios and they have not disappointed me yetI would buy these fans again if I don't already have 4 lol |

Cons: Yeah, pricey. Still not as quiet as they could be.
Pros: QUIET. BEAUTIFUL QUIET for the amount of air their move. Comment:
I bought two of these to go into the front intake of an Antec Three Hundred while putting my own machine together. I had originally intended to use the 800RPM one, but got two of these instead. They are great. Quiet, and they keep everything nice and cool. I've got a Q6600 and 4850 stashed in my tower, and I have never had even the mildest heat worries. Plus the sound is hardly there. |

Pros: Pushes a lot of air, relatively quiet. Comment:
Used four of these in my Silverstone TJ07, to replace the noisy stock fans. Pushes a ton of air while staying relatively quiet. Great quality.Highly recommended! |

Cons: Expensive
Pros: Sturdy frameLow vibrationStarts reliably at low voltage Comment:
This fan is not silent at full speed like some claim, but for a 1200 rpm fan that's to be expected. If you want silence get a 800 rpm fan instead, or a fan controller.Got two of these in the exhaust of my P182 and they force air through the grills better than the crappy vibrating Tri-Cools.The motor is fairly quiet, and doesn't make any offensive electrical sizzling or whining noises.One of my samples has a bit of faint bearing noise, which doesn't go away even at 5 volts, so I think I may have gotten a lemon, the other one has no bearing noise at all. The noise disappeared when placed horizontally, so I just stuck it in the top exhaust position. |

Pros: -Quiet-Well Made-No annoying LED lights!-As good as they get! Comment:
Just like everyone else has said they are quiet, move a lot of air and are some of the best out there. |

Cons: A tad pricey, excessive packaging
Pros: Quiet, seems to move a fair bit of air Comment:
What more can I say, these are good quiet fans. Impressively quiet, really. They do include the mounting screws as well as a converter to power from a molex.I was somewhat disappointed by the amount of packaging included. It's a fan! It doesn't need a plastic box, plastic wrapping over top, all over a cardboard shell. |

Cons: price
Pros: good airflowquiet Comment:
These are excellent case fans. Extremely quiet, added 2 to my case with no noticeable noise increase. I had to check to see if they were actually working because of how quiet they are.The only downside is the price its a bit on the expensive side, I got mine when they were on sale. Highly recommended. |

Cons: not as quiet as I thought (maybe it's the sound of air movement)
Pros: Moves a lot of airNo motor noise Comment:
This fan moves A LOT of air for its speed. I bought 2 of these for my Sonata Designer and ultima-90. Too bad it's not as quiet as I've hoped. I tried to set the fan to run under-voltage (+7v instead of +12v) and I couldn't hear any noise, yet it still provides enough cooling for my stock Xeon E3110. But because I don't like to run it as undervoltage I put it back to normal after. If you don't really care about losing a few degrees of cooling but you want absolute silence, maybe try the D model which spins at a lower rate. |

Cons: None for me.
Pros: Nose? What noise? Comment:
I used bunch of those fans to replace all stock fans in Antec 900 case, which was annoingly loud for my taste.The result surpassed all my expectations. The case is very quet. Fans controlled well by Maximus mobo and reports correct rpm numbers.I have 4 of those inside the case and 1600 version on Nidja heatsink - very pleased with results. |

Cons: made in Chinanot *completely* silent
Pros: quiet S-FDB bearing with very long MTBFdecent airflow Comment:
These S-FDB bearing based fans are great. They have virtually no bearing noise, last something like 4x longer than a ball bearing fan, and don't wear out quickly when mounted horizontally like a sleeve bearing fan.This 1200rpm model is great to put a heatsink. Enough airflow, while being relatively silent. If you're a real silent freak though, I'd consider stepping down to the 800rpm model.It's worthing noting that there is in fact a Noctua fan with a FDB type bearing that will outperform these fans, but they cost a lot more. |

Cons: Only a 3pin connector + standard molex 12v connector. No plugs for 4pin connectors.
Pros: Silent, cheap! Comment:
Dead silent, highly recommend this unit! Paired with a Thermalright 120 extreme head sink, no issues at all. |

Cons: Kept looking in the case to see if it is actually on.
Pros: Quiet! Real quiet. Comment:
Use this as a front case fan to push air in. Q6600 mild. Works great. Don't even notice it is there. Running 100% on all 4 cores and the temps (core, mobo) never gets above 46C. |

Cons: - None yet
Pros: - Quiet - Moves a reasonable amount of air Comment:
Purchased this fan to replace a standard ball bearing fan, and wow what a difference. Cannot even hear this fan, and it moves more than enough air for a front intake fan. Easy to install, and best of all this fan is dead silent. No issues with this fan, and I would recommend it to anyone who wants a quieter system. |
I bought this fan to replace the stock rear one on my Sonata III case. It's plain great! No vibrations, much quieter, and good cfm. Will buy more to upgrade fans on my second box too
