Thermalright 5V ARGB controller: keep the lighting controls close
A PC can have illuminated fans even when its motherboard has no suitable ARGB header. This Thermalright controller takes power from a SATA connection and puts three physical buttons along the cable. It is a compact way to give compatible 5V lighting its own controls inside the case.
Three buttons, a reachable position
The buttons sit on the inline controller, so think about access before tidying the cables. A position behind the side panel can keep the main chamber clean while letting you reach the controls when you want to change the lighting. Avoid burying the unit beneath tightly bundled cables.
Power and lighting follow different connections
Connect the SATA power input to a suitable power lead from the PSU, and the 5V 3-pin ARGB output to compatible lighting. The SATA connector is for power; it is not a drive-data connection.
Check the voltage and pin layout before connecting anything. This unit is for 5V ARGB devices, not 12V 4-pin RGB lighting.
Keep the total lighting load in mind
Thermalright lists a 2A output rating. Check the combined current requirements of the lights you intend to connect, including devices added through splitters. The number of fans alone does not tell you the electrical load of their LEDs.
Fan speed stays on its own circuit
The controller operates lighting. Fan motors still need their separate power and speed-control connections to the motherboard or an appropriate fan hub.
Make the connections with the PC switched off and disconnected, then secure the cables away from fan blades. This controller suits a simple lighting setup where physical buttons are more useful than adding a motherboard-controlled lighting connection.
