⚙️ Hardware Setup, Adjustments & FAQs

❓ My motherboard has a 3-pin header and the fan has a 4-pin connector. Can I connect it? cfg_01
Yes, the 4-pin connector is compatible with 3-pin headers. The fan will operate, but PWM speed control (automatic adjustment) may not be supported by the motherboard. It will likely run at a fixed speed or voltage-controlled speed.
