5 have built 430 housing of these fans in my Cooler Master Elite and am thrilled. These already sheathed connection cable, the integrated anti-vibration rubber mounts, which can even be removed and rotated by "other way" to install the fan. The LEDs light up in a nice, hefty red, just as I had imagined. The only criticism is probably the relatively high starting voltage, because I run the fan at a NesteQ MaxZero 8-channel fan controller, I can only use the level 3 and 4, including the fan not run on. Even at full power the fans are still pleasantly quiet. So I can only recommend.
