I started using noctua fans a few years ago after hearing that they were the lowest noise of the market. I am very pleased that i can ramp this fan to its highest speed and still wonder if I am hearing it. I am glad this fan does not come with RBG, as it is not the purpose of this fan. I recognize that other brands do RGB very well, but I have no interest. I am not going to delve deeply into specific specifications of a fan, just that I see the best quality of parts used and that Noctua offers better cabling options and a splitter with the fan.

I feel like the fans color is the only weakness to most buyers, but Noctua does offer a line of black fans now.

Great performing fan, low noise. Cost is reasonable for a top end segment. Should last me until I need a new case and beyond. Would appreciate if Memory Express stocked the chromax lineup instead of this lineup to expand the group of consumers who would buy the fans.

Quiet I installed 2 fans, one for water block for Corsair H60, other as case fan. I'm quite sensitive to noise and I hate any form of noise. Ryzen 1800X is pretty hot, but with these fans, I cannot hear them when idle, and only start to hear noise when beyond 1000RPM during stress testing, and at max ~1500RPM, , combined, they are still quieter than stock case fan. overall much better than stock fan comes with Corsair H60 cooler.

Expensive

Expensive but worth it, this is the quietest build ever. buy it if you hate noise

Cool and quiet

None so far

I paired these with my Hydro Series H80i High Performance Liquid CPU Cooler and also used them as my case fans. They are so quiet, sometimes I forget to turn off my PC before bed because I can't hear my computer.

Absolutely the best fans I have tried on my Corsair H100i radiator. No electric whirring sound, just a very faint airflow sound. I installed 4 of these in a push-pull configuration (exhausting) and under full load it matches the performance of the stock fans but SO much quieter. Running an I5-4670k at 1.30v for 4.6Ghz - stays under 60C during CPU burn-in testing.

The color of Noctua fans are very distinctive - I personally wish they had more color options as these don't match the bright green color scheme I went with for my build.

If you don't care about noise, there are probably better performers out there. These are by far the best fans I have ever used from a noise to performance ratio - other fans cant even come close. I have tried Scythe/Spectre Pro/Cougar/CM Jetflo / SP-120 Quiet - these are the best.

Super quiet

Cost

You want quiet & performance - you get these. I replaced the stock 2 fans that were on my H100i rad and could not be happier! You get what you pay for!

-Low Noise Fan (Especially with adapters) -HIGH pressure -Good CFM -Comes with adapters to select noise/fan speed.

-Funky Looks -Kinda Expensive

First off, these fans are not standard computer case fans. These are designed for applications that require a fan that can provide pressure, such as water cooling radiators or heatsinks. In these applications this little fan excels. If you are looking for a high CFM fan, or a super quiet fan... then look at some other fans.

Dead silent full speed Moves more than enough air High static pressure Vibration dampening and lots of nicely sleeved cable accessories 6 yr warranty

Brown Price

I'm using these on my h70 and my case and they work great for both applications. Every one says not enough air flow but 99.3 m3/H is still 58 CFM. The only fans that beat these in cfm, stat pressure and Db is the Coolermaster 120mm "long life" fan, I've owned 5 of them and every one stopped working 6 months to a year down the road. These thing have a 6 year warranty! my only issues is the brown which actually isn't an issue since I got my sabertooth mobo. They are worth the extra $ trust me!

-Quality -Quiet -Nicely sleeved wies -Good accessories

-Do not move much air -Expensive

Nice fan but still nowhere as good as a Scythe 1850 rpm Gentle Typhoon in terms of air moved/silence

-quality construction -sleeved cables -extension and splitter cables included

-low cfm -expensive

Bought Noctua fans a long time ago because they were supposed to be the shiz, but I found them lacking and never bought another. After going through many other manufacturers I bought Scythe Gentle Typhoons and have found them to be the best. Unfortunately the Scythe fans are hard to come by so I thought I would try the new Noctuas as they are advertised as a high static pressure fan. Well, they are a very nice quiet fan, but they still do not measure up to the Gentle Typhoons.
