I got this to supplement the stock cooling on my Cooler Master 690 II Advanced case. I found it pretty quiet, with only a very small change in the overall noise level of the system. Depending on system load conditions and ambient temperature, this lowered my case temp by 3 to 8 degrees. It is still quiet enough that I could sleep in the room next door.
While airflow is not the best in the world, this offers a good compromise between airflow and noise level.
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.
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.
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.
Quiet, moves a decent amount of air, high rated MTBF
Cons
None so far....
Summary
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.
Moves a lot of air and quiet High static pressure for pushing air through a heatsink Long life
Cons
For case fans you may be better off with a Kaze slipstream that has less static pressure but is also less bulky.
Summary
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.
Rated for very long life. High airflow for minimal noise.
Cons
Fairly expensive and dull looking for those with a side panel case.
Summary
Rated for very long life. High airflow for minimal noise. Fairly expensive and dull looking for those with a side panel case. Works well with my Thermalright Ultra Extreme.
Noise rating is completely wrong, these fans are louder than they say. Not very much static pressure vs. other fans with the same specs.
Summary
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.
These things rock! I have a dozen of them now on all of my loops and they keep everything nice and cool while being quieter than any of my stock cases fans!
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.
This fan is build really well and sturdy and does not give up much noise for the cooling it does. I would buy this again if I need another 120mm fan. Well recommended.
large fan hub (dead spot for heatsink) Unknown OEM maker
Summary
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 :p would buy again
- Excellent airflow - Good static pressure - Low noise signature if undervolted
Cons
- Loud at full voltage
Summary
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.
- No 4 pin PWM connector, but that's not exactly standard
Summary
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.
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.
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.
Summary
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.

Used on Vendetta 2 and works great for cooling but i think there's a huge dead spot where the fan hub is. Not sure if it affects cooling efficiency. still a great fan
- got it on sale, not expensive - moves a fair amount of air - 150,000 life expectancy - fdb (fluid dynamic bearing) - comes with power adapter
Cons
- not as quiet as everyone says it is
Summary
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.

Would recommend this fan either as a case fan or heatsink cooler. Currently have this set up as top exhaust on Antec P180b and it is working very well.
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
- Good airflow - Not very expensive - Very quiet - Long life span
Cons
- I wish it was sleeved like the Noctua fans.
Summary
The S-FLEX fan is wonderful to work with. I use it in my CM stacker 830 evo case. It snaps into the filters with easy and doesn't even need screws. I'm currently using it as exhaust for the top portion of the case. Seems to do the job so far. I hooked it up to my Kazemaster fan controller and found it wasn't even necessary because of its quiet operation. You can keep this fan going full-tilt and not notice it very much.
No weaknesses thus far, however, I wish I would have gotten the higher RPM fan that was recently released for additional air flow since they are so quiet.

I am using this on my Xigmatek HDT-S1283 cpu heatsink. I cannot even hear it over the case fans. This is my third Scythe fan and probably will not be my last.
I got on of those for my Thermalright Ultra-120 Extreme. Previously, I used to have a Yate-Loon zip-tied to the heatsink and with this fan have seen a slight improvement of about 1-2 degrees. This is definitely a solid product and I recommend it for your TRUE 120's.
Using this as an exhaust fan and another one on a Thermalright ultima-90 and it helps keeps my E8400 nice and cool. It moves lots of air, but is quite audible when running at 1600rpm in my P182 case, quieter than the fans that came with the case though.
Being plagued with a poor fan from the CoolerMaster 500W extreme series, I decided to replace it and chose this Scythe fan. Compared to what the PSU had, it blows a LOT more air and it's very quiet.
The molex adapter came in handy when I had to plug it in since the psu connector only has two pins and the wire setup had the red/black wires inversed from the other fan. Took the wire outside the psu through the cable hole instead and hooked it up to a 12v rail.
120x25mm, all black, open chassis/screw holes, details/tech specs included on box, rated 150,000hrs lifespan, 2yr warranty, Sony's Fluid Dynamic Bearing like what's used on some recent hard drives, 3pin TX3 connector with tachometer RPM sensor, 4pin Molex LP4 to 3pin TX3 adaptor with tachometer RPM sensor bypass so you can monitor RPMs while using a molex power plug.
$12 for a medium speed medium airflow 120mm fan seems reasonable.
Obstructing exhaust has no effect on noise level.
Cons
Packaging was a paper box inside a plastic casing further surrounded by a cellophane wrapper (why so much plastic?)
Faint buzzing sound, like a fly or bee passing by, can be heard during operation. A little noisier than Arctic Cooling 12PWM and Arctic Cooling 12025 PWM.
Airflow feels weaker than 12PWM fan but stronger than 12025 PWM.
Obstructing exhaust has no effect on noise level. No audible vibrations when placed on the floor.
Summary
Very good fan for average airflow, really good longevity. Useful extras/accessories. If they ever make a 100-133CFM fan in this line I'd be interested in trying that out.

This is a great fan, I'm using it with a Thermaltake Ultima-90, and it's keeping my E3110 at 3510 MHz nice and cool (temps always less than 40 celsius, even at load after several hours). Not much else to say, other than this is a fantastic fan that manages to push a lot of air and never be audible, even with the side off my case (Antec P182). Highly recommended!!
Silent yet still moves a considerable amount of air
Cons
Not really a weakess but it is very plain looking
Summary
I have installed two of these in a case and you would think it's a silent wind tunnel in there. Everything runs beautifully cool. The real test will be when I add the second Video card.
I also have the Ninja Scythe Copper without an installed fan. The two case fans are enough.
Purchased this for my Thermalright Ultra 120 Extreme and it keeps my Q6600 at 28C with stock settings. This fan is extremely quite at its rated 1600RPM.
Solid construction Sony FDB Comes with 4 pin adapter and mounting screws RPM reports on my Asus P5K board (not all 3 pin fans will!)
Cons
Too much packaging for a fan!
Summary
I bought this to replace a fan inside my Corsair HX620. Gone is the bearing chatter of the stock fan, replaced with a VERY smooth whoosh. Starts up at low voltages so it's perfect for this PSU, with enough speed in the event things get a bit toasty.
The only thing is that this fan was packaged inside a plastic box which was again sealed in a plastic wrap.
Good Price for a great item! The cooling from this fan is great. I normally have my computer on 24/7 so a bad fan would not bold well for me. Having said that i am very happy with the S-Flex. My core temps have never gone past 40 degrees even on full load. Only downfall is the fan is a tad loud of course i'm comparing it to fans that are more than twice it's price so that might be asking for much. All in all, a very good buy at a even better price, recommended!
Extremely well designed fan using Sony's fluid dynamic bearing technology it's rated to 150,000 hours. It provides a lot of airflow and it's also quiet.
Cons
None
Summary
THe Scythe S-Flex SFF21F cooling fan makes an excellent addition to any system as either a heatsink cooling fan, or case fan. At $12 it's a good deal, and will last for years as it's rated at 150,000.
I have the 1600rpm on my Ultra-120 and it keeps the cooler cool and my temps low. What more could you want? The only thing that bothers me with the Ultra-120 inside my CM 832, I had to take out the top-left fan bracket in order for the Ultra to fit. So, I can only fit three Scythe S-FLEX 1200rpm. Btw, the 1200rpm is slighty quieter compared to the 1600rpm, of course.
Great fan. I have it attached to Thermalright Ultra 120 Extreme and have my Q6600 running at 3.5! I have it set to high, so it is a bit loud but still quiet for a 1600RPM. Would buy this again if needed over others!
Durability Quiet Moves a fair bit of air for 1600RPM
Cons
None really
Summary
Great Heat Sink fan, nice and quiet... Have 2 of theses, one of which was purchased here at NCIX.
They are extremely quiet, more alot of air for their rated RPM and can be used for either cases or HS with great results, I however, prefer using them for the latter. Couple one of theses with a Thermalright heat sink capable of accepting a 120mm fan and you got a winner combination:P
- Sony FDB bearing (fluid dynamic bearing) - 150K MTF! - linear drive IC (very stable speed)
Cons
none
Summary
For a 1600 RPM fan, its pretty quiet. One of the most important features is the FDB bearing. Its similar to the Noctua self-stabilizing oil-pressure bearing. Offers 150,000 MTF (mean time till failure) compare this to a typical sleeve bearing of 30,000 hrs.
Fairly quiet at 1600rpm. Had this on my thermalright and it did wonders for cooling my cpu.
Cons
Would be better if it was available with PWM, this way I could just let my motherboard control the rpm.
Summary
Great product but the Arctic Cooler has one with similiar performance at a cheaper price with PWM. That is what I replaced this with on the thermalright and used this one as chassis fan instead with a fan controller.
Awesome fan. I keep this fan cooling my hard drive and it cools it nicely even when it's undervolted. The only thing that would be awesome on this fan would be sleeving and adaptors to undervolt it.
