Bitaxe LonelyFan Splitter

The Bitaxe LonelyFan fan splitter is a PCB Y-splitter that plugs into the existing fan header on the Bitaxe Gamma 602 and allows it to drive two 4-pin PWM fans from a single header.

If you’re pushing your Bitaxe harder with bigger heatsinks, rear coolers or a push–pull setup, the LonelyFan splitter keeps everything neat while letting two fans follow the same PWM curve. It’s ideal alongside other cooling upgrades in the Bitaxe accessories range, where airflow and wiring can quickly get busy.

The LonelyFan preserves a single stable RPM reading with shared control: both fans receive the same PWM signal; only the left fan returns RPM.

For best results, use matching fans (same model/speed) for better acoustics and more predictable control, and always ensure your combined fan draw stays within the header’s current limit.

Features

• Black PCB: clean, simple design that matches premium builds
• Two fans, one header: PCB Y-split for reliable, compact routing
• RPM feedback preserved: left output = tach/RPM passthrough
• True 4-pin PWM pass-through: Power, Ground, PWM, Tach correctly mapped
• Miner-ready: robust traces and components for 24/7 operation

Resources

Installation

1. Power off your Bitaxe.
2. Plug the splitter into the Bitaxe 4-pin fan header.
3. Connect the fan you want monitored to the left output (RPM reported).
4. Connect the second fan to the right output.
5. Power on and confirm RPM is detected for the left fan in your stats.
