Know before you buy
The reverse blade design pushes air in the opposite direction of a standard fan while maintaining the same aesthetic. This allows you to use the fan as an intake while keeping the visually appealing infinity mirror side facing into your case.
Yes, these fans are compatible with the UNI FAN SL-INF ecosystem. You can connect them together in a cluster to simplify cable management, provided they are the same series.
While the fans will spin without the software, L-Connect 3 is required to customize the infinity mirror lighting effects and adjust fan speed curves. It is the primary interface for managing the frame and blade lighting independently.
Yes, with a static pressure of 2.95 mmH2O, these fans are capable of pushing air through radiator fins effectively. They offer a good balance between cooling performance and noise levels for liquid cooling setups.
You can connect up to four SL-INF 140mm fans in a single cluster to one controller port. This significantly reduces the number of cables visible in your build.
At their maximum speed of 1600 RPM, these fans reach a noise level of 28.6 dB(A). Thanks to the Fluid Dynamic Bearings, the sound profile remains relatively quiet and unobtrusive even under load.
