Noctua NF-S12B FLX 120 mm 3 Speed Setting Beveled Blade Tips

I bought two of these Noctua fans for about $40 bucks I could have had bought 4 Zalman ZM-F3 120mm Quiet Case Fans with Silicon Pins. It is loud at 900 rpm setting which is supposed to be silent mode, it is not, actually it is louder than my Zalman 80mm fan which has been set to 700 rpm’s. The existing Cooler Master fans I have in the case are more quiet at the same speed than Noctua. The fans come with rubber mounts, and 3 speed adjusting cables. One of my fans died an early death after 4 months, and Noctua quickly replaced it with a new one. These fans were so good that I replaced my CPU cooler with one from Noctua as well. Having spent a lot of time searching for the best 120mm fans for my case I had decided to go with Noctua, which was backed by great reviews all over the net.
