The Delock 91342 PWM Fan Splitter Cable 1x 4-Pin Female to 3x 4-Pin Male 40 cm Black is compared against similar Delock cooling accessories: the Delock 91341, Delock Y-Fan Cable 91338, Delock Fan Cable DC (91355), and Delock USB Type-A (91343). All these products facilitate fan connections, but they differ significantly in supported fan quantities, power sources, cable lengths, and control mechanisms. While the Delock 91342 is designed to connect up to three fans to a single motherboard header with PWM support, the alternative models focus on dual-fan setups, USB power, or external DC power sources with manual switches.
⚙️ The table below compares key specifications such as source connection type, number of supported output fans, cable length, PWM support, and control features to illustrate practical differences in real-world use.
| Parameter | Delock 91342 | Delock 91341 | Delock Y-Fan Cable (91338) | Delock Fan Cable DC (91355) | Delock USB Type-A (91343) | Practical Conclusion |
|---|
| Power Source Connection | 4-pin PWM (Motherboard) | 4-pin PWM (Motherboard) | 4-pin PWM (Motherboard) | DC Jack 5.5 x 2.1 mm (External PSU) | USB Type-A (USB Port) | Delock 91342 draws power directly from a motherboard header with PWM control, unlike alternative models powered via USB or an external DC source. |
| Supported Fans | 3 fans | 2 fans | 2 fans | 2 fans | 2 fans | Delock 91342 offers higher capacity by supporting three output fans instead of two, maximizing cooling options from a single header. |
| Cable Length | 40 cm | 30 cm | 13.5 cm | 1 m | 1 m | The 40 cm length of the Delock 91342 provides better reach and easier cable management in larger PC cases compared to shorter variants. |
| Switch Control | None | None | None | Included (Manual) | Included (Manual) | Delock 91342 relies on automatic motherboard PWM regulation, whereas models with switches offer manual power control. |
◎ The table below evaluates how well each product fits specific user needs and use cases to help you choose the most suitable option for your setup.
| Use Case | Recommended Product | Why |
|---|
| Connecting three fans to one motherboard header in a spacious PC case | Delock 91342 | With support for three fans and a generous 40 cm length, this cable is ideal for expanding cooling capacity while maintaining automated speed control. |
| Connecting two fans to a motherboard in a standard or compact build | Delock 91341 or Delock Y-Fan Cable (91338) | These models are better suited when only two fans need to be connected, with the 91338 offering an ultra-compact length for tighter spaces. |
| Powering cooling fans outside of a PC or without a motherboard header | Delock Fan Cable DC (91355) or Delock USB Type-A (91343) | These adapters are necessary when motherboard headers are unavailable and power must be supplied via a USB port or an external DC adapter. |
The Delock 91342 stands out from the alternatives by enabling three 4-pin fans to connect to a single motherboard header with a convenient 40 cm reach. It is best suited for PC builders looking to expand their cooling system with automated PWM speed regulation without cluttering internal headers. Choose this product if you need to manage multiple fans efficiently inside a standard or large computer case.
