Noctua don't use a standard plastic for their fan rotors. They use a proprietary liquid crystal polymer, which is stiffer and more dimensionally stable than polycarbonate or PBT. This allows for tighter clearances between the rotor tips and the fan shroud and reduces vibration of the rotor...

Assembled PCBs are washed in water at the end of the manufacturing process to remove flux residues - typically a detergent mix followed by a deionised water rinse, with either spray or immersion washing. Outside of a few specialist applications, solvent-based PCB cleaning is obsolete for...
