Noctua, the most well known brand in cooling and a leader in its fan designs for years, has added to its line up of ultra high end quiet 5V fans with new 200mm, 140mm, 120mm, 92mm, 80mm and 40mm models. These new 5V models of the existing critically acclaimed NF-A20, NF-A14, NF-A12x25, NF-F12, NF-A9, NF-A8 and NF-A4x10 designs will be available both in 3-pin and 4-pin variants, the latter supporting PWM-based speed control. All fans include a USB power adaptor cable that allows them to run on USB host devices, power banks or USB power supplies.

While the existing NF-A4x10 5V and NF-A4x10 FLX (12V) models have become a popular choice for 3D printer hot-end cooling and are now used in the latest Prusa i3 MK3 3D printer, the new 5V PWM and PWM (12V) versions are ideal for 3D printers that offer PWM-based speed control as well as all other 40mm applications with PWM support. By contrast, the new 5V and 5V PWM versions of the award-winning NF-A8 (80mm), NF-A9 (92mm), NF-A12x25 (120mm), NF-F12 (120mm), NF-A14 (140mm) and NF-A20 (200mm) are larger than any of Noctua’s previous 40 and 60mm size 5V offerings and thus aim to open up new markets that range from bigger devices and home appliances all the way to cabinet cooling, green walls and room ventilation. A welcome addition to Noctua’s already massive lineup
