Quote:
Model: SFF21G
Fan Size: 120mm x 120mm x 25mm
Speed: 1900 RPM
Airflow: 75.0 CFM
Noise: 34.0 dBA
Bearing: S-FDB* (Sony patent pending Fluid Dynamic Bearing)
Voltage: 12 V
Current: .24 Amp
Fan Life: 150,000 hours
Connector: 3pin (length: 30cm) with 3pin to 4pin connector w/ separate RPM
Fan Screws: 4 fan screws included
*S-FLEXâ„¢ is registered trademark of SONY Corp.

Description:
The 120mm S-FLEXâ„¢ series from Scythe utilizes Sony's Fluid Dynamic Bearings to create a high quality fan with an incredible noise to CFM ratio. At only 34.0 dBA, the Scythe SFF21G (1900 rpm model) pushes an astounding 75.0 CFM! Innovations such as the S-FDB technology, additional suction magnet, and linear drive IC all contribute in eliminating noise and wear, drastically extending the life of the fan up to 3 times the amount of conventional ball bearing fans. The 120mm SFF21F S-FLEXâ„¢ fan from Scythe is great for any application; this 120mm fan pushes more than enough air for any case/heatsink application and is also recommended for radiator setups.
Great fans IMHO only second to Sanyo Denki San Aces... Will probably buy one of these for comparison's purposes.

I love the 1600RPM versions, but I wonder how good these are? I might have to pick one up and find out for myself.

They are probably using "real" values.

Similar Yate Loons do 70.5CFM for 33dB so it seems reasonable.

Personally, every S-Flex fan I've owned has been quieter than similarly rated fans... You really shouldn't look at the dBA alone because different types of sounds may have the same "noise level" but that doesn't make them the same by any means. As DuckieHo mentioned, some Fan maker's ratings aren't necessarily all that accurate *cough* Silenx *cough*. Oh and don't get me started on Yate Loons, they were pretty bad too, in terms of ratings and actual "noise level"(Still can't complain too much given their price).

The Scythe S-FLEX fans with the ferrofluid filled motor are phenominal (say that 10 times fast!). By far in my quest for quiet fans, the SFF21F moves the most air with the least noise. Happy to hear a faster version is on the horizon! Great products, thanks for the post.

can you say over priced? i have a m8 with a couple of them and they are good but i dont think they are much better than the sflexs.


people say the sflex is over priced but they are almost half the price of the noctuas over here.

tbh my case is full of the sflx f and im more than happy with the levels as its only late at night i can hear them on full.

might get me a "g" for my cpu heatsink tho

I just don't understand. I have Scythe Slipstreams. Same 1900 RPM, except rated at 110.31 CFM instead of 75, and 37dBA instead of 34. And they only cost me $8.99 a piece. Why doesn't everyone go with these? IMO, they are rated SO much better. And I don't hear the fan motor, only the air moving. I have no complaints about these fans.
