Moves more air than Noctua and quieter too, but do take control of its speed.
I used this tiny fan to cool my video card. The outtake side was on a sunflower heatsink, and the intake side was less than 1cm from the outside of my computer. That close proximity to the outside was the source of a lot of noise. Its noise is a bit more noticeable than Thermalright's 92mm slim fan, and it seems louder when moving the same amount of air, so I favored Thermalright in my tiny computer.The fan does move decent air, isn't too noisy when not confined between 2 pieces of metal, and it does the job pretty well. I would suggest this fan to anyone building in tiny SFF cases. It's not my favorite, but it's certainly better than the popular beige Noctua fans that show up in so many builds. Replacing the fan on a Noctua L9a/L9i with a Scythe Kaze Flex fan might improve your temperatures a bit and help cool CPUs that aren't officially supported by that heatsink.

Good fan
So far they do what I want. They are quieter than my old fans, but are also not the most quiet out there.

Great case fan, and better alternative to Noctua
If you need a slim 92mm fan like I did in my Ncase M1, this is the one to get. You don't get all the extras that come with Noctua fans. but you do get a fan that performs better, for less money. Definitely would recommend!

Good cooling performance but incredibly loud, and better alternatives
About 1.5C cooler (78C vs 79.5C core, 80.8C vs 82.2C average die temp) than the noctua nf-a9x14 but significantly louder, and the sound is a very annoying high pitch. It's only 0.4C cooler (78.4 vs 78 core, 81.2 vs 80.8 die) than the ID-Cooling TF-9215 ARGB which sounds better, is quieter, is cheaper, and has RGB if your into that.The lower temps did lead to a slightly higher cinebench score and higher clocks, but the sound is not worth the ~0.5% bump in performance imoTesting was done in a Velka 5 with a 5600x3d. I took the average temp after cinebench r23 was run for 10min. I only tested these fans at max speed so I'm not sure how they compare below that.I'll update this with a comparison to the air slimmer 92mm and thermal right TL-9015B when I get them.

High Pitch Whine
I really wanted to like it but it has a distinct high pitch noise that is very noticeable even will my 6 other fans going. Only used it for about 2 hours before starting my return, I mean it does the job but the sound was very annoying.

Quite but still doesn’t beat the ugly brown noctua
Tried 3 fans in the back of my Ncase m1 - noctua chroma - really loud high pitchThen this one it got me 80% where i wanted. Not bad but not quite.Ended up with noctua brown 92m - silent and does the job. I hate the color.If i were you and you have a specific color scheme. Still buy the brown noctua. It’s the only silent option.

Initial impressions
Why I bought this fan - I have an older prebuilt PC that has a single 92mm fan slot for exhaust. I had been using an older Noctua 92mm (which was not very loud) but it's speed was only 1800 RPM. Although it worked OK, the deficiencies of the case design are such that one fan pretty much has to do all the work. I wanted to buy something with a higher speed but did not want to entirely sacrifice quiet operation. I have found over the years that fans that make more of a whooshing noise are much less annoying even at higher decibels than fans that have an annoying background hum. Thankfully, this fan is one of the former. It is by no means silent at anywhere near it's full speed but the sound it does make is surprisingly not as irritating as you'd think for such a small fan spinning at over 2000 RPM. Seems to move a lot more air and I can see the temp difference so for now, I'm happy with it.

Not recommended. The material is really bad. The screw holes broke at first installation.
Functional, but the material is really bad. I bought 3 fans, total 12 screw holes. 3 screw holes broke at first installation. Not recommended.

A very good slim 92mm fan for the price
Bought this to be use on my SFF case for the CPU cooler fan swap. Definitely performs better than the noctua 92mm slim fan although at the cost of being louder since this Scythe fan spins faster. If you are sensitive to noise then I suggest going to the noctua fan but if you want a lower price and better performance fans then this is the fan to get.

Works as described
Works well under normal conditions. I have to admit tho it's not as quiet as Noctua under high load.
