Frequently Asked Questions
Q: Will this 4-pin fan splitter cable work with 3-pin fans?
A: Yes! While designed primarily for 4-pin PWM fans, the connectors are backward-compatible with 3-pin fans. When used with 3-pin fans, speed control will operate in voltage mode rather than PWM mode, depending on your motherboard's capability.
Q: How many fans can I connect with this splitter cable?
A: Depending on the variant you choose, this splitter supports 1-to-1, 1-to-2, 1-to-3, or 1-to-4 fan connections from a single motherboard header. Be sure your motherboard header can supply sufficient current for all connected fans.
Q: Does this cable support automatic fan speed adjustment (PWM)?
A: Yes. This cable supports automatic PWM speed control, allowing your motherboard to dynamically adjust the speed of all connected 4-pin fans simultaneously based on system temperature readings.
Q: What is the maximum temperature this cable can handle?
A: The cable is rated for operation up to 80°C, making it suitable for the internal environment of most standard and high-performance desktop PC cases.
