This PC case comes with four pre-installed ARGB fans: three 140 mm fans at the front and one 120 mm fan at the rear. These fans are connected via standard 3-pin power connectors and 5V 3-pin ARGB headers for lighting control. The fans are not connected by PWM for speed control, as the included ARGB controller board does not support PWM fan control. Instead, fan speed can be managed by connecting the fans directly to the motherboard if it supports 3-pin fan control. The ARGB lighting can be controlled via an ARGB-capable motherboard or the case's integrated color selection button.

In summary:
- Number of fans: 4 (3x 140 mm front, 1x 120 mm rear)
- Fans are ARGB with 5V 3-pin lighting connectors
- Fans use 3-pin power connectors (no PWM speed control via included controller)
- ARGB lighting controllable via motherboard or case button

This setup provides efficient cooling with customizable lighting but does not include PWM fan speed control through the case's controller.
