Details
The Barrow DK301-16 is a 16-way hub and controller for fans and 5V addressable RGB lighting. It is powered by SATA and has 16 six-pin outputs that each carry a fan connection and an LRC 2.0 lighting connection. A toggle switch chooses who drives the lighting: the included RF remote, or your motherboard through the included adapter cable.

16 outputs for fans and lighting
Each of the 16 headers has six pins, marked 5V, D1, GND, 12V, FC and PWM: the three lighting lines of Barrow's 5V LRC 2.0 system and the lines of a 4-pin PWM fan. Barrow says the hub connects most Barrow and Barrowch products.
What you can connect
- Barrow LRC 2.0 lighting connectors, fan lighting connectors and the Barrowch water temperature meter with color screen.
- Fans with a 4-pin PWM power connector.
- Barrowch flow meters with a 3-pin, 3-wire connector.
- Barrowch water temperature meters with a 3-pin, 2-wire connector.
Remote or motherboard
A toggle switch in the middle of the board sets the mode. In ON the hub's own controller runs the lighting and you change it with the RF remote. In OFF you plug the 500 mm adapter cable into the 5V ARGB header of the motherboard, and the motherboard software controls the lighting, including its temperature and music modes. Barrow names ASUS Aura Sync among the compatible systems and points to the motherboard makers for other brands. The square fan plug of the same cable goes to a motherboard fan header, so the fans follow the motherboard fan curve.
The remote
- Power button switches the lighting on and off.
- MODE+ and MODE- step through the light modes; AUTO cycles them automatically.
- SPEED+ and SPEED- set the effect speed in 5 levels.
- R, G, B and W switch to red, green, blue or white light.
- ADD DIY stores the current mode, DEL DIY deletes it, DIY+ and DIY- switch between stored modes.
Fan speed reading
Barrow says that on hubs delivered after 28 October 2020, the motherboard reads the fan speed only from the fans on one color-coded group of headers shown in its diagram. If the reading is unstable with many fans connected, Barrow says to remove the FC (speed signal) pin of the other fans.
Mounting
The hub is 6.6 mm thin. Fix it with the adhesive pad on the back (peel off the backing) or with screws.
