Jonsbo UPSIREN PRISM UF-1 4 PRO Fan Features and Specifications
The UF-1 4 PRO operates across a 600 to 1500RPM speed range managed entirely by your motherboard through a standard 4-pin PWM header, so the fan scales cooling output to match actual system load rather than running at fixed speed. At peak performance it moves 45.2CFM of air, a figure that places it competitively against fans in higher price brackets without introducing the noise those higher-speed units create. ARGB illumination runs on a 12V 3-pin ARGB header and synchronizes with all major motherboard lighting ecosystems, giving every build a consistent light show without adapters or secondary controllers. The fluid dynamic bearing at the hub center reduces friction compared to sleeve bearings, extending rated service life and keeping noise floors low during long overnight render or NAS workloads. Order from the official Jonsbo store today to receive the best price, verified authenticity, and fast shipping to your door.

The fans are perfect, the RPM is high, it ventilates well and the ARGB works very well, good lighting, but I made sure to put an LED strip internally in the cabinet because I like the predominance of white among the RGB. In the end, they turned out beautiful, 1 regular fan at the back and 5 reverse fans. Here in Brazil, a fan like this is much more expensive, even with the tax it’s worth it, it makes the L Taxad mald1to.
