High-Performance 4-Pin PWM Fan Y-Splitter Cable for ASIC Miners

When pushing your open-source Bitcoin mining hardware to its maximum hashrate, optimal airflow is an absolute necessity. This 4-pin PWM Y-splitter cable allows you to power and control two high-RPM cooling fans from a single controller header, ensuring perfectly synchronized thermal management across your mining rig without needing separate power adapters.

Whether you are upgrading the cooling on a Bitaxe Gamma, configuring a custom Nerdaxe QAxe setup, or building an extreme cooling enclosure for your NerdQX or NerdOctaxe, this adapter is engineered for the heavy power demands of dedicated ASIC cooling. The splitter passes the PWM control signal to both fans while routing the RPM tachometer feedback from only one. This crucial design prevents your miner's control board from receiving conflicting readouts, ensuring stable, precise fan speeds to keep your chips hashing efficiently.

Key Features

• Synchronized Cooling Control: Ramps both fans up or down simultaneously based on your ASIC's thermal loads to prevent thermal throttling.

• High-Current Capacity: Built with high-quality wiring to safely handle the heavy power draw of high-RPM server fans used in custom mining enclosures.

• Streamlined Rig Management: Consolidates fan wires to keep your open-source hardware setups clean, ensuring unhindered airflow across your heatsinks.

• Broad Miner Compatibility: Works seamlessly with standard 4-Pin PWM fans, ideal for Bitaxe, Nerdaxe, and DIY miner repairs.
