You can connect it directly to the motherboard. If it does not support it, a separate fan cannot be used and must be used with an ARGB controller. Forward wind direction is generally suitable for the top and back of the chassis, and reverse wind direction is generally suitable for the front and bottom of the chassis. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
