The NF-A4x10n is custom, frameless version of the award-winning NF-A4x10 fan.

The NF-A4x10n uses the same, proven impeller design as the regular NF-A4x10, which enables it to achieve outstanding performance-to-noise efficiency. At the same time, the frameless version with its three small mounting tabs is ideal for direct integration into custom heatsink designs and compact devices where it can be helpful to push air out both in axial and radial direction.

Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make the NF-A4x10n an elite choice for integration into durable, premium grade devices that combine optimal cooling with excellent quietness of operation.

For B2B clients, we can offer the NF-A4x10n in 24, 12 or 5V variants with customised cables and connectors. Please contact us at b2b@noctua.at if you’re interested in integrating the NF-A4x10n.
