Description
TL;DR: The DK401-7 consolidates seven PWM fans and seven lighting devices onto a single hub that draws power from a 5-pin SATA connector on a 500mm lead. Lighting output is switchable between 5V 3-pin A-RGB (LRC 2.0) and 12V 4-pin RGB so the same hub can drive either standard. The board also exposes 3-pin...
The DK401-7 consolidates seven PWM fans and seven lighting devices onto a single hub that draws power from a 5-pin SATA connector on a 500mm lead. Lighting output is switchable between 5V 3-pin A-RGB (LRC 2.0) and 12V 4-pin RGB so the same hub can drive either standard. The board also exposes 3-pin headers for 3-wire flow meters and 2-wire temperature sensors, and the sync header forwards motherboard A-RGB signals so the hub can chain with Aura Sync, Mystic Light, Gigabyte Fusion, and ASRock Polychrome controllers.
Q: How many fans and lighting devices can the DK401-7 drive?
A: Up to seven PWM fans and seven lighting devices, each with its own header.
Q: Which RGB standards does the hub support?
A: Selectable 5V 3-pin addressable RGB (LRC 2.0 compatible with Aura Sync, Mystic Light, RGB Fusion, Polychrome) and 12V 4-pin non-addressable RGB. Do not mix the two on the same channel.
Q: How is the hub powered?
A: A 5-pin SATA power connector on a 500mm cable. The hub does not draw power from the motherboard fan or RGB headers.
Q: Can it read flow or temperature sensors?
A: Yes. The hub includes 3-pin headers for 3-wire flow meters and 2-wire temperature sensors, in addition to fan and RGB outputs.
Q: Important warning about 5V vs 12V?
A: Plugging a 5V 3-pin A-RGB device into a 12V 4-pin header (or vice versa) will permanently damage the device. Verify the output mode before connecting LEDs or fans.
