Frequently Asked Questions

Q: Will this 4-pin to dual 3-pin PWM fan splitter work with my motherboard?

A: Yes — this splitter is designed to be compatible with standard PC motherboards that feature a 4-pin PWM fan header. The two 3-pin output connectors can power and control most standard 3-pin case fans. Always verify your motherboard's fan header type before purchasing.

Q: Can I control the speed of both fans independently with this splitter?

A: Both fans connected via this Y-splitter will be managed together through your motherboard's PWM fan speed controller, as they share the same header signal. Independent per-fan speed control would require a dedicated fan controller hub.

Q: Is any installation or assembly required?

A: No assembly is required. Simply connect the 4-pin plug to your motherboard's fan header and plug your two 3-pin fans into the output connectors — it's a true plug-and-play solution.
