Noctua industrial PPC specifications clearly put them in another class from other consumer grade fans. The SP noted below means static pressure, the pressure a fan makes when its outflow is blocked. Note how little current these fans draw.
IP codes cover intrusion protection from everything solid from fingers to dust, and water protection from light sprinkles to full immersion. The IP code 5- means that the equipment is dust-proof (of several references consulted, Wikipedia was the clearest). A code of 6- means it is dust tight – no dust gets in at all. The IP code -2 means that the equipment is proof against a light rain, as long as it is canted to at least 15 degrees. The IP code of -7 means the equipment can handle being submerged up to 1m depth for as long as a half hour. So Noctua warrants that its normal iPPC fans are dust proof and can handle a light spray, while their IP67 fans can tolerate a good dunking. Well, we’ll see.
But now we were curious: how well protected are normal Noctua fans? Vortez wrote to Noctua. They responded, “The standard ones are not certified, but would qualify as IP5X (dust protection but no water protection).” So those codes were added to the spec table above.
If you have looked for aluminum frames or water proofing or other protections in the fans made by other manufacturers, you know how hard they are to acquire and how much they cost. You will normally pay quite a premium for ruggedized fans. Noctua’s MSRP for the IP67 fans is $34.90/€29.90, less for IP52 fans (see Noctua’s product line page).
The Noctua industrialPPC fans also have SSO2 bearings, three phase electric motors and a six year warranty.
