When Noctua announced they had released 24-volt fans, I ignored it, asking, “What does that have to do with me?” I had tried 24-volt fans from other manufacturers with unhappy results. But the Noctua rep told me “They actually run nice and quiet in 12V PC environments!” It was at that point I had to test these fans to see how well they do. Do they really run quietly at 12 volts? And how strong are they? Immediately thereafter, Noctua announced their Chromax line of accessories. From having these two releases coming so close together, this combined review was born.
