Build Quality

At 420g, the unit is small but surprisingly heavy – we took this as a good sign. The NF-A9x14 PWM fan blades moved effortlessly with the flick of a finger and we instantly noticed the build quality of the whole platform, from the fan, the heat sink itself and the cable braiding (as usual for Noctua).
