Review on Noctua NF-A14 iPPC-2000 PWM 4-Pin Heavy Duty Cooling Fan – Ultimate Performance at 2000 RPM (140mm, Black) by Xavier Xavier (Xavie ᠌

Assuming that the higher the price, the better the product, I made the purchase. I was right, by the way. What initially caught me off guard was how stable it felt in my hands after I turned it on. Nothing except a smooth spin from it. As I increased the software's maximum speed, it was faintly audible over the hum of the other coolers, but normally it would be impossible to distinguish. The wind is picking up, and you can feel the system unit's draft on your legs. Most alternative coolers quickly deteriorate, which is a major drawback. If you don't hear him the first week, give it a couple of months, and he'll be roaring like a lion. The enormous backlash that appears when you shake the screw after purchasing one is instantly apparent. Noctua coolers use a special bearing made of brass that has been machined to a high degree of precision and has magnetic self-centering; the bearing is sealed with oil seals and runs on liquid lubricant. It's not for nothing that the guarantee is for six years; this method makes it quite unlikely that anything will break rapidly.
