Daisy-chaining cooling systems

Serial connection

— the capability to connect multiple fans and/or ARGB lighting into a single chain with one connector to the motherboard or controller simplifies wiring and speeds up assembly. This approach reduces cable clutter and results in a clean interior but comes with limitations: the entire chain operates under one PWM/DC profile, and the real speed is detected by the motherboard from one sensor, so fine individual tuning is not possible. Compared to a hub, daisy chaining is simpler and cheaper, while compared to individual connections, it's more compact and quicker to install; however, with a long chain, there can be voltage drops and ARGB signal degradation, so it's better to limit to 3–4 fans per chain or use branded bridges/controllers. Before installation, it's worth checking the rated current of the motherboard connector and the total consumption of the fans, especially with 140mm models and "turbines" up to 3000 RPM. Typical scenarios include quick PC assembly with three frontal 120mm fans, a 360mm AIO radiator, or neat lighting from multiple ARGB fans without excess wires.
