Our numbers have it putting out less noise at 1200 RPM than some fans running 300 RPM slower. Of all the fans we tested, this model pumped the most air through our test rig.īut-and this is important-the NF-A12x25 was also the quietest fan we tested when running at lower RPM. The Noctua SF-12B 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. Here's some good ol' Noctua khaki-and-mud for the diehards.

That's a lot of money, even if the results are stellar.

To use LL120s, you need to commit to purchasing a three-pack of fans with an included Corsair Lighting Node Pro, a package that lists for $120. At mid-range speeds, we found during testing that they tend to be slightly louder than the competition, but at load, they're quieter than just about any non-Noctua fan we tested-and that's only because most of the Noctua fans top out at 1200 RPM, versus 1500 RPM for the LL120. The LL120s are also solid fans, lighting or no. As a result, the LL120s are the brightest and showiest fans we tested and a perfect fit for any RGB addict. Then, a separate ring of light is embedded around the housing's outer edge. Each has a complement of LEDs shining out from the rotor, diffusing light down the blades' length as they spin. They can look great in an all-glass case or even through a traditional side window, and if you're chasing that full-cyberpunk aesthetic, then Corsair's LL120 Pro RGB fans are the best you can buy.
