EDITOR's Note - these fans are for industrical applications and not for CPU cooling. CPU heatsink fans run on 12V DC."Noctua today expanded its line-up of premium-grade quiet 5V fans with new 200, 140, 120, 92, 80 and 40mm models. The new 5V versions of the existing award-winning 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.
“We’ve seen a growing demand for 5V fans from our industrial clients, the 3D printing community and DIY customers who seek to replace noisy 5V fans in devices such as DVRs or network and storage solutions,” explains Roland Mossig (Noctua CEO). “Several years ago, 5V was a niche market, but today there are more and more devices using 5V fans and our PWM-enabled 5V fans give engineers unique options to increase customer satisfaction by using sophisticated speed control in order to achieve quieter operation.”
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.
“With the abundance of power banks and compact USB power supplies for smartphones, using one of these to power a 5V fan has become one of the easiest ways to tackle your everyday cooling needs,” says Roland Mossig (Noctua CEO). “Some extra ventilation for your A/V cabinet to protect that expensive home cinema receiver? Some extra airflow on your desk or in your bedroom? These are the everyday applications where our new, larger 5V fans step in!”
All of the new 5V models include a USB power adaptor cable that allows the fan to run on devices with USB host ports, power banks or USB power supplies such as those used by smartphones. When replacing existing 5V fans, the supplied OmniJoin™ adaptor set makes it possible to connect the new models to proprietary fan headers and, thanks to the integrated polarity protection, there’s no risk of damaging them due to reverse polarity.
Like all Noctua fans, the new 5V and 5V PWM models feature an MTTF rating of more than 150,000 hours and come with a full 6-year manufacturer's warranty."
