Noctua NF-S12B redux-1200, High Performance Cooling Fan, 3-Pin, 1200 RPM (120mm, Grey)

Nice design and quite at low RPM. Color scheme is nice as well. I think the cougar that this replaced moved more air and was quieter.

Excellent cooling fan for computers. Easy to install and fits most tower type desktop computer cabinets. Easily wired and promotes a high flow rate of cooling air over the interior of the cabinet. As far as I can tell the fan blades in number and angle are quite effective as opposed to other cooling fans of its size and package dimensions. I easily recommend it for the case cooling requirements of most desktop computers.

Very good

Absolutely as advertised. These fans are silent yet they move air keeping the computer cool. A dramatic improvement over the stock CoolerMaster fans that came with the case.

I love these. Theyre quiet and last forever.

Very quiet little 120 mm fan that moves a nice amount of air. These replaced a pair of case intake fans called the Ultra Kaze (by Scythe). For some reason, I had been enticed by the sheer power of the Ultra Kaze fans, but the noise was really starting to bother me. This little Noctua fan is nice and quiet, and it draws a sufficient amount of air into my case to handle the heat produced by overclocking. I kept the same overclock settings after installing this fan, though your mileage may vary. I like the new gray color of Noctuas Redux line.

Easy to understand instructions even easier to install. only downside are the colors

...and easy to install. This fan replaced an old PC fan that had become annoyingly noisy. Best PC-part investment Ive made in a while -- instant relief, and itll probably perform noiselessly for years.

Just replaced my rear case exhaust fan (Corsair) with this (NF-S12B Redux-1200) and the system is quieter and runs a surprising 10 degrees cooler! Very pleased.

Fantastic case fans by a company that exudes quality. I tossed 3 of these along with a Noctua DH14 in my newest build, all fit perfectly in a Corsair Carbide 540 case. They are ultra quiet and move enough air to keep a monster rig cooled, even under the harshest of conditions. Cant speak highly enough about this company and its products. You will not be disappointed.
