Scythe S-FLEX SFF21F 120MM Cooling Fan 1600RPM 28.0DBA 63.7CFM FDB
Cons:None Noticed Thus Far.
Pros:* Moves Air Well, And Quietly Comment:
I purchased 2 of the fans as intakes in my Antec 300. Thus far they have performed well, though I would expect no less after only 2 weeks of operation.Regarding noise, I can absolutely hear a difference in overall noise when these are running vs not running. It still doesn't disturb me, I'm just saying I can certainly hear a difference. |

Scythe S-FLEX SFF21F 120MM Cooling Fan 1600RPM 28.0DBA 63.7CFM FDB
Cons:Low static pressure
Pros:High CFMLong lifeLow(ish) DBA Comment:
This fan pushes a lot of air and works great for circulating a case or on heat sinks which don't require much static pressure. This fan should virtually last forever so you shouldn't have to worry about replacing it for a few builds. |

Scythe S-FLEX SFF21F 120MM Cooling Fan 1600RPM 28.0DBA 63.7CFM FDB
Cons:None so far....
Pros:Quiet, moves a decent amount of air, high rated MTBF Comment:
Picked up this fan to add to my TRUE CPU cooler, to make up a push/pull setup, but wanted something to move a bit more air, so I replaced it shortly after.As mentioned earlier, this fan does move a decent amount of air, while being fairly quiet, and another plus, is the large MTBF of 150,000 hrs., which, theoretically, should mean this fan will last a relatively long time, and quite possibly outlast many computer fans. |

Scythe S-FLEX SFF21F 120MM Cooling Fan 1600RPM 28.0DBA 63.7CFM FDB
Cons:For case fans you may be better off with a Kaze slipstream that has less static pressure but is also less bulky.
Pros:Moves a lot of air and quietHigh static pressure for pushing air through a heatsinkLong life Comment:
Have two of these on my Thermalright Ultra 120 black edition hsf. They move a lot of air (1600 rpm) and are quiet. 1600 rpm seems to be the way to go for processor cooling. These have high static pressure and are thus excellent for heatsink cooling. Good ball bearing rated for long life. Excellent choice. |

Scythe S-FLEX SFF21F 120MM Cooling Fan 1600RPM 28.0DBA 63.7CFM FDB
Cons:Noise rating is completely wrong, these fans are louder than they say.Not very much static pressure vs. other fans with the same specs.
Pros:Good CFMLong life. Comment:
Overall this is a good fan, I cant complain, but I am not impressed with the noise the bearing makes. Maybe most cant hear it, but unfortunately I can and it is loud. Has a high pitch wine to my ear. I replaced the fan in the event that it was a bad fan (happens with the best) but no change. I compared this to another fan with the same airflow and the other fan was far quieter. However, this fan is still good, and the lifespan makes it worthy. |

Great fan with good airflow. Comes with screws and 3pin to 4pin adapter. Keeps at the case/cpu nice and cool without *too* much noise. |

Scythe S-FLEX SFF21F 120MM Cooling Fan 1600RPM 28.0DBA 63.7CFM FDB
Cons:Quite loud. Kinda expensive.
Pros:Very good airflow Comment:
The is the best fan you can get if you want ultimate airflow. If noise is an issue, then don't buy this. This thing is not a jet engine but can put out a fair bit of noise. At 1600rpm that is expected. The the air is pumps out is unrivaled. If you are overclocking on air and want a super cool pc,, get this fan. Price is definitely worth it. I have this on a fan controller, so i can spin it down to 800rpm when i dont need the cooling and then max it out while im gaming. |

Pros:High CFMDecently queitSony FDB Comment:
Nice fan for heatsinks that dont require mad static pressure and its a Sony FDB so it should last decently long.Used mine on OCZ Vendetta 2 over stock fan and its quieter.Only thing is they use 4 pin fan header since its more common now and my mobo only allows speed control with PWM :pwould buy again |

Scythe S-FLEX SFF21F 120MM Cooling Fan 1600RPM 28.0DBA 63.7CFM FDB
Cons:- Loud at full voltage
Pros:- Excellent airflow- Good static pressure- Low noise signature if undervolted Comment:
An excellent all around fan. Can be undervolted to about 9V to achieve a even quieter noise signature otherwise it's a bit loud. If not used for a heatsink it makes for a very good case fan (though expensive).One wish for the future is that Scythe would include rubber grommets for mounting the fan instead of providing screws. |

Scythe S-FLEX SFF21F 120MM Cooling Fan 1600RPM 28.0DBA 63.7CFM FDB
Cons:- No 4 pin PWM connector, but that's not exactly standard
Pros:- Quiet- Moves a lot of air Comment:
This fan does what it says: it moves 64 cfm at 28 db. I can't hear this over my CPU fan, so it qualifies at quiet for me. I like that Scythe includes a Molex->3 pin converter, which happens to include a plug for motherboard fan headers with just the sensor - very useful if you need to use a Molex connector, but still want to monitor fan speed. |

Pros:Very quiet, excellent results Comment:
Installed two to replace case fans on a P182 case and find these are much quieter. Also installed on a Ultra-120 on a E8400 running at 4ghz and keeps the temps nice and cool.Very happy with results. |

Scythe S-FLEX SFF21F 120MM Cooling Fan 1600RPM 28.0DBA 63.7CFM FDB
Cons:Only a 3-pin connector. No way to physically toggle fan speed (stays at 1600rpm - my stock could be switched between 1200,1600 and 2000; feedback toggling only with the 4-pin adapter and appropriate software.Slightly louder than I like case fans to be.Annoyingly short packaged screws.
Pros:It moves a lot of air. Comment:
Got a properly functioning air extrication device, though Speedfan hasn't noticed much-touted decreases in temperature after installing it. The s-flex has a long operating life and for that much I'm grateful. This review was modfied by poster @ 09-16-08 02:00 PM |

Scythe S-FLEX SFF21F 120MM Cooling Fan 1600RPM 28.0DBA 63.7CFM FDB
Cons:- not as quiet as everyone says it is
Pros:- got it on sale, not expensive- moves a fair amount of air- 150,000 life expectancy- fdb (fluid dynamic bearing)- comes with power adapter Comment:
This 120mm fan moves a fair amount of air and at 28 dba, its not loud but not super quiet either. Excellent build and got it on sale, so I bought three, two for the back and one for the front. If you want near perfectly silent fan, get the 40 dba version of this fan. The 67 dba is not too bad but you can hear it hum away. I recommend this fan as the loudest possible solution and it moves alot of air. This review was modfied by poster @ 07-22-08 07:01 PM |

bought some of them recently and i should agree they're so nice and quiet. easy to set up with controller, not the first fan i buy from them and probably not the last one too;p |
Got this fan to use in a puch/pull on Coolermaster Hyper 212 cooler. it does an excellent job at moving the air. I noticed that the stock cooler has an almost unbearable whine at anything over 1500 RPM, so had to change MB settings to keep it below that. AMo going to order another of these to swap out the original.
