Frequently Asked Questions
Q: Will this 4-Pin PWM fan splitter cable work with my motherboard?
A: Yes — this cable is designed for standard 4-Pin PWM CPU fan headers found on virtually all modern desktop motherboards (ATX, Micro-ATX, Mini-ITX). The input end features a 4-Pin PWM connector; the three output ends are 3-Pin fan connectors compatible with most 3-Pin case fans.
Q: Can I use this cable to connect PWM (4-Pin) fans, or only 3-Pin fans?
A: The three output connectors on this cable are 3-Pin, so it is best suited for connecting 3-Pin (voltage-controlled) fans. If your fans have 4-Pin PWM connectors, they will still fit physically on a 3-Pin header but will run at a fixed speed without PWM speed control.
Q: How many fans can I safely run from one motherboard header using this splitter?
A: This cable supports up to three fans simultaneously from a single motherboard header. Always check your motherboard's fan header current rating (typically 1A per header) and ensure the combined current draw of all connected fans does not exceed that limit to maintain safe and stable operation.
Q: Is any installation or assembly required?
A: No assembly is required. Simply plug the 4-Pin end into your motherboard's CPU fan header and connect your case fans to the three 3-Pin output connectors. The cable is ready to use right out of the box.
