Noctua NF-F12 PWM 120mm Case Fan

Pros: Much quieter than the stock fans that came with my Corsair H100i. Also keeps it cooler than the stock fans. Works well with the CorsairLINK software. No obnoxious LEDs.

Cons: Not quite as quiet as I would like when running at full speed. The colors Noctua uses doesn't match my case and does make it look out of place.

Other Thoughts: Perfect design for radiator cooling due to the high static pressure. They keep air moving through my radiator with ease.

Pros: Great warranty, good frame construction, quiet at the right RPMs.

Cons: They are ridiculously expensive! Questionable rating tactics to bring the buyer in and stick lots of the right numbers down the specifications list to seal the deal. They use differing units of measurement to produce the desired statistic, whether an inflated or deflated number

Other Thoughts: Noctua has the same tendency as Arctxx Coolxxx when rating their products. They use whatever unit of measurement is best suited to grab your attention when reading the specs or the overview. A good example is the NF-F12 fan. They do several things keep your interest in purchasing their product. First is the use of m³/h rather than CFM. This figure converts to 55.0126 CFM. That is not a staggering or humungous amount of air flow. Another thing they do at the Noctua site is list three different RPMs with the BIG m³/h air flow numbers, but they only list two examples of static pressure. I have 3 different Noctua fans. They sit on a shelf gathering dust, while fans less than half their price, that flatly stated CFM and static pressure at either intended RPM, or at each RPM example given for lower noise, have done the job build after build. Beware the use of sone when it comes to fan loudness. There is no direct conversion to dBa. When a company has to resort to trickery, misleading, bait & switch and inflated or deflated numbers via changing they type of measurement, and confused methods of rating products, they should be examined with caution and each specification verified to make sure the product is what it is making itself to be. At half the price, these fans would be worth it. These are mid-to-low CFM fans with questionable static pressure to pull air through good dust filters, or push and/or pull through radiators, and with a laughably high price tag.

Pros: Quiet, decreased cpu core temps by 1 degree on Noctua NH-U12P heatsink. An improvement over Noctua's other 120mm fan. Good warranty, good tech support. After 5-6 months both fans leaked some yellowish lubricant. Noctua responded to my email quickly and have sent me 2 new fans.

Cons: These fans don't move a tremendous amount of air, but they are quiet. They are expensive, but great warranty and support

Other Thoughts: These fans are a balance between quiet and moving air. They are quiet. Other fans might move more air, but make more noise. These work well, and the tech support is rapid, email is usually answered the next day. Noctua backs up its products.

Pros: It is pretty quiet, It pushes a fair amount of air, the noise adapters and rubber fittings are good which reduce vidration and noise through out your case.

Cons: They are not EXTREMELY quiet(dont get me wrong they are quiet but not extremely)
Very expensive fans
Dont push a hugemongous amout of air.

Other Thoughts: I have another type of fans brand name is a type of wild cat and they are orange, they are also PWM and i think they are best for an overall value meaning (airflow,noise,price)

I am tradeing the noctua's for another pair of these fans that i mention above
but its just my opinion

Pros: Quiet, PWM, removable rubber corners, selection of cabling options, 6 year warranty

Cons: expensive but in my opinion worth it

Other Thoughts: Bought as a replacement for my hyper 212+ cpu fan that made a weird grinding noise. My room is so quiet now!

Pros: Build Quality is about as good as it gets.
Quiet when running under 1200 RPM.
Great static pressure.

Cons: Price may be a little higher than most want to spend.
Color may not be your cup of tea but it doesn't bother me.

Other Thoughts: Amazing fan, there are other fans in the same class but Noctua does not disappoint.

Pros: - Very quiet at 1250 RPM or below
- Comes with extensions, adapters, rubberish bolts
- Rubberized 4 corners for reduced vibration (removable)
- Cables are sleeved

Cons: As mentioned in below feedback, when fan hits 1450 RPM, the noise gets significantly loud, probably louder than regular 1450 RPM fans.

Tested with:
1x 1450 RPM Antec Kuhler fan 120mm
1x 1450 RPM Corsair 600T Case fan 120mm

Comparing with those fans, they were much more quiet at 1450 RPM than Noctua fan at 1450 RPM.

The loudness at 1450 RPM is not high pitched coil noise or anything but just louder.

Other Thoughts: To benefit most out of this fan, keep it under 1250 RPM at all time and enjoy the absolute silence.

Pros: It has a 6 year warranty! Very nicely directed airflow, watch some smoke test videos on youtube if you don't believe me. Pretty much unnoticeable noise at 1200 rpm(see cons). Nice sleeving included on all wires including the adapters, though it is an odd rubber-like sleeving. Neat freaks will be happy to know the heatshrink goes practically all the way on the wires only maybe a millimeter showing(I know that bothers some modders). I'd call the price high and say it's a con, but noctua has put a lot of R&D into this, and it has a very long warranty for a fan, so consider that when you think about the price.

Cons: With the L.N.A.(forces the fan top speed to 1200rpm) you'll hear next to nothing unless maybe your pc is already super silent, but I can hear it when it ramps up to 1500 rpm. That being said it's a low pitch hum and isn't nearly as bad as my 600t's case fans. Even though it's built as a guided airflow/higher pressure fan, it didn't improve my CPU tempuratures(see other thoughts). So I'm guessing it's better for an intake fan since it pushes air in such a well guided path.

Other Thoughts: I haven't done long stress testing, but quick tests to see what pretty much my max temp is around. Long enough for the temp to pretty much stabilize, and using prime95. I'm running this on the Xigmatek HDT-S1283 with an Intel C2D wolfdale e8400 overclocked to 3.4ghz, with a max temp of 52C, but this fan didn't seem to improve that tempurature compared to the stock Xigmatek one. I'm sure it might do better for radiators though for those using liquid cooling. This was all done during the winter, so my room doesn't heat up like it does in the summer for anyone who would like to know.

Pros: Lots of accessories, runs quiet and pushes solid amount of air. Nice cable sleeving. Get what you pay for.

Cons: Who picked the color scheme?

Other Thoughts: I like noctua fans and will continue to buy them when needed for future purposes. Maybe they could put out a 200mm fan line.....

Pros: very quiet and does a good job

Cons: none

Other Thoughts: replaced the stock fans on my corsair h100-they were jet turbines-these are awesome-tried the cougar vortexes but they dont work on radiators in the top of your case when using as exhaust-noctuas are great for this
