Frequently Asked Questions
Q: Will this 4-pin PWM fan splitter work with my motherboard's fan header?
A: Yes. This splitter uses the standard 4-pin PWM connector that is universally compatible with virtually all modern motherboards. Simply plug the male connector into your motherboard's 4-pin PWM fan header and connect up to three fans to the three female outputs.
Q: Can my motherboard control the speed of all three fans connected to this splitter?
A: Absolutely. Because this is a true PWM splitter, the PWM signal from your motherboard is passed to all three connected fans simultaneously, allowing your motherboard to regulate all fan speeds automatically — just as it would with a single fan.
Q: How long is the cable and is it suitable for large PC cases?
A: The cable measures approximately 30 cm (11.81 inches), which is suitable for most standard and mid-tower desktop cases. The sleeved, flexible design also makes routing and cable management straightforward in a variety of case layouts.
Q: Does this splitter require any additional power connection?
A: No additional power connection is needed for the splitter itself. Note that when powering multiple fans, the total current draw of all connected fans should remain within the safe output capacity of your motherboard's fan header (typically 1A). Check your motherboard manual for specific header ratings.
