The Noctua Chromax Black Fans are truly the best of the fans on this website. These fans are versatile, suitable for radiators, cases, or tower coolers, and they perform exceptionally well while keeping noise to a minimum. The fans use a fluid dynamic bearing which helps reduce noise. The fan speeds vary as there are multiple types of these fans (three to be exact). This fan has enough static pressure to lower temperatures by around 4 degrees Celsius compared to stock fans designed for certain coolers. These fans also have a long lifespan without their bearings wearing out. While most fans usually last 3-4 years of continuous operation, these fans have lasted well over 8 years and are still spinning strong. The main downside is the cost, as these fans are typically 2 to 3 times more expensive than other fans of the same size.
I give the Noctua Chromax Black 140 Fans a 5/5.
