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

These are nice and silent on my LARGE pc and wish the cords were a little longer to connect to the fan headers as they had to travel from the top of the pc to the inside MB.

These fans are great and dont look half bad for Noctua fans, but if you want to use them for a radiator or air cooler, DEFINITELY get the PWM model (they are the same price!!). This will allow for change in speed so that they arent running at max speed all the time. Even at max speed, however, they are quite quiet, probably the quietest thing in my computer.

Very good

I have a sleeper build that I utilized both this fan add well as its big brother. Works well and cant complain with noise. Good product.

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.

I have now bought 5 of these and I wont use anything else. As the title says they are extremely quiet. They do However move a lot of air. I have 4 mounted in my case and the fifth I used to replace the noisy Corsair fan on my CPU water cooler. To my surprise, the Noctua is not only quieter but my average resting CPU temp is 2 degrees cooler. Under load, it goes up to between 3 and 4 degrees. Fantastic fans at a bargain price!!

Everything about it is great for a low power, quiet, Mobo controlled fan. And good price. If it lasts a year I will add another star as it will have been perfect.

Not much to say. Ultra quiet.

Had to replace a stock case fan in my Cooler Master Cosmos (2007) case. Installed without difficulty; running silently. Over the years, all the fans Ive installed were made by Noctua - always had top reviews at the time I needed them. Totally recommend Noctua.

I just had a fan fail. It was one that came with the case. Sleeve bearings just suck. But, I had installed a Noctua with the CPU cooler, and its been cruising along nicely. So, Noctua was a natural brand choice to replace the cheap-ass sleeve-bearing fan that failed.
