This product page focuses on the Delock 91341 PWM Fan Splitter Cable 1x 4-Pin Female to 2x 4-Pin Male 30 cm Black, which is compared with alternative fan connection solutions from the same manufacturer: Delock 91342, Delock Y-Fan Cable (91338), Delock Fan Cable DC Jack (91355), and Delock USB Type-A (91343). All these products serve to connect multiple fans, but key differences lie in the power source type, number of supported fans, cable length, and additional features such as manual switches.
⚙️ Below is a comparison of characteristics such as the number of supported fans, cable length, power source type, and connection interface.
| Parameter | Delock 91341 | Delock 91342 | Delock Y-Fan Cable | Delock Fan Cable DC Jack | Delock USB Type-A | Practical significance |
|---|
| Connection type | Motherboard (4-pin) | Motherboard (4-pin) | Motherboard (4-pin) | External power supply (DC Jack) | USB Type-A | The power interface determines where the cable can be used—inside a PC via the motherboard or externally via USB and DC sources. |
| Fan count | 2 fans | 3 fans | 2 fans | 2 fans | 2 fans | Models supporting three fans allow connecting more cooling units to a single header than standard two-fan options. |
| Cable length | 30 cm | 40 cm | 13.5 cm | 1 m | 1 m | Greater length suits larger cases, while shorter cables help maintain a tidy layout inside the PC. |
| Speed control | PWM | PWM | PWM | No PWM | No PWM | PWM support enables the motherboard to automatically adjust fan speeds based on thermal loads. |
◎ The table below evaluates various usage scenarios and buyer needs to help choose the most suitable cable option.
| Use case | Recommended product | Why |
|---|
| Connecting two fans to a motherboard with standard cable reach | Delock 91341 | Provides an optimal 30 cm length for neat cable management in standard PC cases while supporting PWM control for two fans. |
| Connecting three fans to a single motherboard header | Delock 91342 | Allows combining three fans on one port and offers an extended 40 cm length for larger system builds. |
| Compact two-fan connection in tight builds | Delock Y-Fan Cable | Features a shortened 13.5 cm length to prevent excess cable clutter in compact enclosures. |
| Powering fans from an external DC power source | Delock Fan Cable DC Jack | Equipped with a DC 5.5 x 2.1 mm connector and manual switch for custom cooling setups outside a PC. |
| Powering fans via a standard USB port | Delock USB Type-A | Enables powering two fans from a USB port with an integrated switch when motherboard headers are unavailable. |
The Delock 91341 cable is ideally suited for standard PC builds where two 4-pin fans need to be connected to a single motherboard header while maintaining automatic speed regulation and a manageable 30 cm length. If you need to connect three fans or require alternative power interfaces like USB or DC, other Delock models will be more suitable.
