◎ The suitability table below evaluates product alignment with different use cases to help you select the most appropriate option for your specific setup.
| Use case | Recommended product | Why |
|---|
| Powering cooling fans from a standard USB port with manual control | Delock USB Type-A to 2 x 4-Pin Fan Adapter Cable with Switch, 1 m | Delivers power from a conventional USB port and includes an integrated manual power switch. |
| Connecting two fans to a motherboard with automatic PWM speed regulation | Delock 91341 PWM Fan Splitter Cable 1x 4-Pin Female to 2x 4-Pin Male 30 cm Black | Splits a single motherboard header into two fan connections while retaining speed feedback. |
| Setting up a three-fan cooling array from a single motherboard header | Delock 91342 PWM Fan Splitter Cable 1x 4-Pin Female to 3x 4-Pin Male 40 cm Black | Enables efficient management of up to three cooling fans inside a standard computer case. |
| Powering fans from an external DC power supply unit | Delock Fan Cable DC Jack 5.5 x 2.1 mm to 2 x 4-Pin Fan Connector with Switch 1 m | Features a DC jack designed for autonomous power setups outside the computer chassis. |
| Compact internal PC routing for two PWM fans | Delock Y-Fan Cable 1x 4-Pin PWM Female to 2x 4-Pin PWM Male with Braided Sleeve 13.5 cm | Provides a short, protected cable layout ideal for clean cable management without excess slack. |
| Specialized industrial or legacy multi-port data tasks | Delock Y-Cable Adapter LFH D-Sub HD 60 Pin Male to 2 x 4-Pin Male 0.3m | Designed for specific signal transmission through high-density interfaces rather than fan control. |
The Delock USB Type-A to 2 x 4-Pin Fan Adapter Cable with Switch, 1 m stands out by drawing power from a standard USB port and offering an integrated manual switch, making it the ideal solution for custom setups lacking available motherboard headers. If your application requires automated motherboard speed control or connection to an external DC power supply, alternative Delock models will be more suitable.
