The NZXT RF-AF12C-RB Case Fan is a set of two 120mm fans designed for computer cases. These fans feature a rifle bearing for smooth and efficient operation, with a maximum fan speed of 1500 RPM. The black fans have a 3-pin power connection and are compatible with universal brands. Made of plastic and with a sleek black color, these fans are a reliable and stylish addition to enhance cooling performance in your PC setup. Untested told they were working. Selling as is. Since they are untested is why I’m selling at a lower cost.
