darkFlash RC2 4-Pin PWM Fan Controller Grey

The darkFlash RC2 4-pin PWM Grey is a multi-port fan controller that supplies both PWM and ARGB lines to multiple system fans and lighting devices. Designed to sit inside a PC case, it offers centralized fan speed control and basic lighting management with a neutral grey finish that integrates into most builds.

Advantages

The RC2 outputs up to six sets of ARGB+PWM signals, supports up to 14 lighting effects controllable via the reset button, and secures to the case using two strong rear magnets for stable installation. Its 4-pin PWM interface enables precise fan speed adjustments to balance cooling performance and noise.

Suitable for

• Desktop PC builds requiring multiple PWM fans and ARGB lighting control
• Gamers and system builders seeking quieter, better-regulated cooling
• Upgrades where compact, magnet-mounted controllers are preferred

Key specifications

• Interface: 4-pin PWM fan control with ARGB signal output
• Outputs: Up to 6 combined ARGB + PWM outputs
• Lighting modes: 14 selectable lighting effects (controlled via reset button)
• Mounting: Two integrated magnets for tool-free attachment to metal case surfaces
• Color: Grey housing

How to use

Mount the controller to a suitable metal surface inside the PC case using the built-in magnets. Connect fans to the 4-pin PWM outputs and connect ARGB lighting devices to the corresponding ARGB outputs. Use the system reset button to cycle and select one of the 14 lighting effects; fan speeds will be managed via the PWM control signal from the motherboard or an external PWM source according to connected fan headers.

Recommendations

Install the controller on a clean, flat metal area inside the case and ensure firm magnetic contact. Verify motherboard fan headers or an external PWM source are configured correctly to provide PWM control. Avoid placing the unit where it may contact moving components or obstruct airflow.
