To start things off, let’s take a look at the industrialPPC’s. For some reason Noctua went a little conservative with this line. They are only available in 120mm and 140mm options, but each size has four different variations. IndustrialPPC fans come in high RPM models all the way up to 3000 RPM. They have three phase motors, fiberglass reinforced fan blades, and even water and dust protection in a few of the fans. If it isn’t obvious, they didn’t just recolor these fans to black and call it a day. They really did design fans for industrial use; they just took that opportunity to put out a black fan to also please some of the enthusiasts looking for black fans to math their builds. The industrialPPC’s clearly improve on the quality of Noctua’s fans (who ever thought this was possible) so they are a little more expensive than standard Noctua fans. You still get a 6 year warranty that all Noctua fans have, just in this case they can last that long in a more rugged environment.
