Cable Matters 2-Pack PC Fan Splitter Cable - 30cm, 4-Pin PWM Splitter 1 to 3 Converter, 3-Way Computer Fan Cable

Triple Fan Connection Solution: This 4 pin fan splitter cable connects 3 computer case fans to a single motherboard fan header; the 4 pin PWM fan splitter shares the PWM control signal from the master 4 pin fan connector to the slave fans for improved airflow in your computer case

Unified PWM Control: This PC fan splitter connects to a 4-pin motherboard fan header and shares one PWM control signal with up to 3 compatible fans, helping them follow the same fan control curve for coordinated cooling in a desktop PC

Synchronized Speed Monitoring: One master connector reports RPM speed back to the motherboard, while the follower connectors omit the RPM signal pin to prevent conflicting tachometer readings; compatible with 4-pin PWM fans and many 3-pin case fans, subject to motherboard fan-control support

Spare Cable Convenience Pack: Cost-effective 2-pack of computer fan splitter 4 pin cables provides a spare cable for adding fans to increase cooling; the 30cm pc fan extension cable and sleeved black case fan splitter cable keep computer accessories tidy in an open computer case

Wide Compatibility for Enhanced Cooling: PWM fan splitter cable supports computer case fans such as Cooler Master Hyper 212 EVO 120mm, MegaFlow 200mm, and 230mm case fans; ideal as a 4 pin fan 3 splitter when a basic fan splitter 2 way is not enough for your cooling setup
