Summary: I have a R9 295x2 overclocked 9% memory 30%, and CPU overclocked over 5ghz in a single loop on a triple 120mm rad. Keeps my temps at 2 degrees over ambient running benchmarks. I'm only running three of these badies in a pull configuartion. Just impressive.
Pros: Wow Just Wow. These things can move air. I have them in a Pull configuration on my Radiator. They are quieter (alittle) then the (competitors) SP120's that I have at max rpm, and move about twice the air.
Summary: I obtained a CPU cooler, the Noctua NH-U12S, which comes with one of these preinstalled. I obtained a second NF-F12 PWM to mount on the cooler in a push pull configuration for exhausting air toward the rear panel of a Raijintek Aeneas cube case housing a Xeon workstation built for content creation.
Pros: Excellent quality. Six year warranty. Solid performance. Quiet operation.
Cons: High price. Color scheme. Specialized use. Not completely silent.
Pros: I needed a new fan for the front of my NZXT ATX Mid Tower case. Rather than going with another conventional fan I decided that a decent fan should go in front of my hard drive cage. Researched Pressure fans and the Noctua Industrial fans came out as one of the best if not the best fan available. ...
Cons: The brown color of the rubber I do not like, but I can not argue with the results.
Summary: It is loud at high RPM. You should expect this.
Pros: Keeps my rad cool. Fast and configurable. PWM is nice. The Black and brown is so much better than the tan and brown. Nice rubber slips for the corners to keep vibration down.
Cons: Upgraded my mother board and CPU a couple months after buying and using these. Used a Y splitter to hook them both up to one fan plug. After moving to the new system, one fan refused to start spinning. Didn't matter where I plugged it in, or even trying the same plug that the working fan was plug...
Summary: What can you say? These are the best fans on the market. Strong, durable and well built. Been running Noctura fans for the last ten years, NEVER had any noise or vibration, let alone a failure.
Pros: Quiet, high flow rates, fluid bearings and built in vibration pads.
Summary: Spent a premium for what I thought to be premium fans for my Swiftech H220-X. One of them was DOA out of the box. The other one is painfully loud. There are videos on youtube of the noise this thing makes, and it has a very distinct high-pitch whine to it.
Pros: Solid construction Look great Sleeved PWM cable Amazing packaging
Pros: Very impressed with these fans. They feel very well built and when lowered to around 900 rpm you can't hear them(this does depend on your case as well as I can hear them in the 380T but not the R5). Pulling air through my H220-X and temps are great.
