Cableless ARGB 120 mm Fan

This 120 mm case fan uses a cableless design that connects units together in series, reducing internal wiring. Double-sided ARGB lighting provides consistent illumination whether the fan is mounted facing inward or outward. The white frame suits clean, light-themed builds. It functions as a standard case intake or exhaust fan and can also replace a fan on an all-in-one liquid cooler.

Builders Who Want Fewer Cables

The daisy-chain mounting system suits builders who prefer a tidy interior without individual fan cables routed to a hub. ARGB synchronisation works with standard 5 V addressable headers. Buyers who need variable-speed control via a 3-pin voltage header should look elsewhere, as the unit relies on PWM signalling. Anyone requiring a non-illuminated fan for a stealth build should consider a different model.

Cableless Daisy-Chain Connection

The defining specification is the cableless series connection that lets multiple fans share a single power and signal path. This mechanism removes the need for a separate fan hub or multiple motherboard headers. Verify that your motherboard or controller provides a 4-pin PWM header and a 5 V ARGB header to drive the chain.
