  • ColorBlack
  • LEDARGB

Option 3 Packs

  • Double-sided ARGB lighting for consistent front and back illumination
  • Building-block series splicing reduces cable clutter inside the case
  • Strong air volume accelerates internal heat dissipation
  • PWM control enables automatic speed adjustment to thermal load
  • Compatible with case mounting and AIO radiator replacement

Cableless ARGB Fan Trio

The Mechanic Master KaKaLock Magic Cableless KL120 arrives as a three-pack of 120 mm case fans with double-sided ARGB lighting. Black frames suit stealth builds while the cableless daisy-chain design keeps internal routing tidy. PWM control allows the motherboard to regulate speed automatically.

PWM And ARGB Header Limits

Each fan draws power and signal through a single PWM header, so the motherboard must supply enough current for three units in series. ARGB synchronization likewise depends on a single 5 V addressable header and compatible software. Builders with only one header of either type cannot expand further without a splitter or controller.

Double-Sided Lighting Constraint

The defining specification is illumination on both faces of the frame, which lets the fans glow consistently whether mounted as intake, exhaust or on a radiator. Buyers who only need single-sided lighting or who prefer traditional cabled fans will not benefit from this design.

Questions about this item

Should I pick the 3-pack or a single 120mm fan?

The 3-pack gives you three identical 120mm ARGB fans in one box, so you can populate front, top and rear positions with matching lighting and airflow.

What does the 120mm size mean for my build?

A 120mm fan fits standard 120mm mounting points on most cases and radiators, delivering focused airflow for CPU coolers or case ventilation.

How does the cableless design connect to my motherboard?

The fans link together in series using a building-block connector, so a single PWM and ARGB header runs all three units without extra cables.
