Cable Matters 2-Pack 2 Way 4-Pin PWM Fan Splitter Cable, 4 inches

Why it's a great deal

• Dual Fan Connection: This PC fan splitter Y cable connects 2 computer case fans to a single motherboard fan header. This 1 to 2 case fan splitter is ideal for adding an extra fan to boost airflow inside your computer case.

• 4-Pin Fan Header Support: Mobo 4 pin fan splitter connects to the 4-pin header on your motherboard and splits the PWM signal to 2 PWM fans. Both fans can spin at the same speed using motherboard software with PWM control support.

• Sync for Consistent Speeds: Master/slave PWM splitter includes a 4 pin fan connector that transmits the RPM signal to the motherboard, ensuring synchronized fan speeds for both fans. The computer fan splitter omits the RPM signal pin on the second fan for tandem operation.

• Tidy Setup with PWM Y Cable: Double CPU fan splitter supports up to 4 fans using this cost-effective 2-pack of fan header splitter cables. The black-sleeved and wrapped 4-inch PWM Y splitter cable ensures a clean and organized build—perfect for open computer cases.

• Works with 3-Pin & 4-Pin Case Fans: 3-pin & 4-pin fan compatible with popular cooling fans such as Corsair Air Series AF120 80mm / AF140 High Airflow, Cooler Master Blade Master 80 / Master 92, Cooler Master Hyper 212 EVO 120mm, JetFlo 120mm, SickleFlow 120mm, MegaFlow 200mm, Noctua NF-F12, and Thermaltake WATER 3.0 Dual 240.
