Here's some good ol' Noctua khaki-and-mud for the diehards. The Noctua NF-S12B above is a great fan and our overall pick, but if you're looking for a top-tier 120mm model that can move a lot of air, the awkwardly named NF-A12x25 blows away the competition. Of all the fans we tested, this model pumped the most air through our test rig.But—and this is important—the NF-A12x25 was also the quietest fan we tested when running at lower RPM. Our numbers have it putting out less noise at 1200 RPM than some fans running 300 RPM slower. Since those mid-range speeds are generally more likely to come up in day-to-day use, the NF-A12x25 is an excellent choice for your average gaming PC while still giving it the headroom to spin up to 2000 RPM in the middle of a heatwave.Sure, Noctua's trademark brown fans will stick out like a sore thumb in whatever PC you build, but they're also a sign of quality, and the NF-A12x25 lives up to the legacy. It's also a nice touch how many accessories come with the NF-A12x25, from a 12-inch extension cable and a Y-splitter to many rubber vibration dampers. The price is high, but it's hard to argue the value.For pretty much any application inside your PC, then, the Noctua NF-A12x25 is a great choice.
