Conveniently installs on any 120mm mount, (despite the fan itself getting 140mm) and moves a ton of air for its size. It tends to make a wonderful front intake fan, especially if you don't want LEDs lighting up your case like an x-mas tree. This fan is very easily the loudest a single in my system. At max RPM it emits a quite audible growl.If you're going to use a lot of these you may want to invest in some sound dampening padding or a fan controller. When it's operating at 50% or lower it stays fairly quiet. If you don't mind the noise, these are great fans.

High CFM. 120mm mount holes. Would have bough if it was a common 140mm.

Fantastic fan.Scythe brand.Lots of CFM. Does not fit on the Armageddon's clips because of its funky size. WHY IS IT ROUND?!WHY DOES IT HAVE 120mm screw holes?! I'm so frustrated with this construct.I tried H70.. and it was DOA.Now I got my Armageddon in and I can't even use it due to the fact these *&%$ fans are funky. Good.

For a 140mm fan it is nicely above average, where as most spin at 700-1000 rpm & don't do significantly. the cfm is superior per db, its making a fantastic front hdd fan in my CM gladiator 600, my drive went from an avg. 30C to 28C with room temp @ static 22C, I didnt need to have it but wanted to attempt Scythe & figured a new item would be a excellent choice. Note that this fan is considerably louder than most 140s, but nothin like my Delta 4.8 Amp 120mm. The rpm is the reason I purchased this fan. Not a con, but warning; the blades are common 140mm fan style but the mounting holes are 120mm socket style, most 140mm sockets are 120mm in a position, but check for the holes. For the cfm I have 120s that do the exact same but at 23db... Whoever decided 140mm should be so significantly far better that 120, I strongly dislike them.. I got a new case (Antec Lanboy Air) which doesnt fit 140s, which is good for me due to the fact I also got 15 CM Smoke non led fans, ive found that the led versions of the similar fan whine, hmmm, this a a wonderful fan; but I'm not converting from a 120mm lover :)

Quiet, effective, excellent airflow, straightforward to attach, attachments for molex and threeǚpin fan headers Ɣpin has the added pin for pwm management). Cheap, rapid shipping. None Newegg is the ideal

Cons: cables not sleeved, somewhat expensive (currently $16.99ea before price-match)

Pros: low voltage, high RPM, low noise level, pushes lots of air
I've done quite a bit of research on fans in the 120mm and 140mm catagory. Because Scythe's 120mm Gentle Typhoon (highly acclaimed by pretty well every web resource from message boards to pro reviews to youtube for superior noise:airflow ratios) is out-of-stock damn near everywhere, I went with Scythe's larger fan: Slip Stream 2 (also known as Kazemaru 2).While the available information in the 140mm fan catagory is not yet as comprehensive as it is in the more popular 120mm catagory (reason why I was reluctant at first to invest in a 140mm fan), the bulk of information I was able to find noted the Slip Stream/Kazemaru 2 as having superior noise:airflow. What can I say - I'm a believer. I purchased five of these, and at full RPM they're pushing an impressive amount of air while also maintaining a very low-noise profile. I will caution that because these are made to be mounted in 120mm mounting holes (convenient for cases lacking in 140mm mounting holes), some difficulties may arise when attempting to mount these side-by-side. However, this challenge is nothing that can't be overcome with some simple case-modding, and shouldn't deter enthusiasts away from this product.Also, I recommend a fan controller for use with the higher RPM models (such as this one which I clocked at just over 1800 RPM) to control RPMs when higher airflow might be sacrificed in favour of further noise-lessening (gameing vs. surfing the web or word processing).I would like the cables to have come sleeved, but I'm not going to be seeing them inside my case anyhow, so no real foul. Awesome fan overall. Do some research before running out to purchase anything else. Oh, and on that note: I price-matched mine at about $11. When purchasing in bulk, those dollars add up!

Until I realized its a 140mm at 1700rpm with 120mm mounting wholes. I utilised two of these in a push pull setting with Corsairs H50 water cooler program. These fans push an s load of air via, dropped my temps by two*C. None so far. Corsair 800D case with H50 water cooler. Thankfully I read the previous assessment or I would have missed the fact that these have 120mm mounting holes. My initial intent was to mount this in a location that only had 140mm mounting holes.

Cons: Not a weakness, but watch out as the fan blades are sharp and will cut your knuckle if touched while running.

Pros: Extremely quiet, at full speed it doesn't even register over the sound of my hard drives. Super air flow!!!
I bought this fan to help with general cooling in my home server. I was looking for something with hi CFM and low dBa. This is definitely the fan! The one side of the fan has 140mm screw spacing while the other side is for 120mm screw spacing making it compatible with most cases, very handy for most cases which may not have 140mm fan spacing. This also enables it to be hooked up to a fan heatsink.I liked this fan so much I bought a second one for another PC.

Cons: not really

Pros: Really good fan for the price
The more it goes the more i love Kazemaru fans, so far i had the 800rpm version and love it and this one is great, way cheaper then the Noctua and this one is making more cfm and it's easier than the Noctua to use with low voltage.

Cons: Won't fit many 120mm applications due to it's size.

Pros: 120mm mounting holesWork well on a fan controller.No funky LED's or color schemes.
I bought 3 of these fans for intakes on the front of my Thermaltake Armor. It took a bit of engineering but I made them fit...lol! Overall I'm pleased with their performance. 140mm fans move way more air than 120's. I must warn you though that this particular model is 1700RPM and they are very loud when running at full speed. I could not bear to be in the same room with the noise they create  but I have them hooked up to a Scythe fan controller and run them at 1200-1300RPM and they are nice and quiet. So make sure you have a controller or just buy the lower speed fans to begin with.I can't detect any motor noise and the fans undervolt well all the way down to 500RPM so I'll give them 5 stars!

Cons: Wires are not sleeved140mm fan which only fits 120mm mounting holes

Pros: Pushes a fair bit of air at max speedConstruction quality is solid
The scythe's were a toss up when I cracked the box open and tried it out.It pushed a very good amount of air through the case and the noise level wasn't extremely bad for what its worth.The problems with this fan is that it is a 140mm fan that ONLY fits into 120mm mounting holes. There is no adapter that comes with the packaging for 140mm mounting. So beware when you buy this.Also, a minor point, wires are not sleeved

Review Date: 11/27/10
Cons: nothing

Pros: Great airflow
Is about as loud as advertised. Not quite as annoying as i thought it was going to be. I have no way to test but it should be pushing close to what they say if not slightly higher.Fits any 120MM screw holes. Will not however fit all of the 120mm case fans etc as the sides will be too wide.
