Yeston Zeaginal 120mm 4Pin PWM RGB Fans (4 Pieces).
This a Pack of 4 RGB 120mm fans. I'm the original owner and I bought these fans roughly 1 year ago and these fans still work just fine. The RGB aspect comes from the ring around the edge of the fan blades.
These fans come with the Original Box and come with the mounting screws.
If you have any questions, feel free to ask. Thanks and take care.
