1-to-8 PWM Fan Hub SATA Molex 3-Pin 4-Pin Speed Controller
Take full control of your PC's airflow with the OULLX 1-to-8 PWM Fan Hub. This compact splitter hub lets you connect up to 8 fans simultaneously from a single SATA or Molex power source — ideal for gaming rigs, mining setups, and water-cooled systems that need clean, organised cable management and reliable fan control.
⚠️ Important Voltage Note: High-speed mode operates at 12V. Low-speed mode operates at 5–7V. If your fan does not support low-voltage start, it will not spin at low-speed setting. Please verify your fan's minimum start voltage before use.

Frequently Asked Questions
Q: Can I connect both 3-pin and 4-pin fans to this fan hub at the same time?
A: Yes! The OULLX fan hub supports multi-channel 3-pin and 4-pin fans running simultaneously. All 8 output ports are designed for 3-pin connectors, but 4-pin fans will also connect and operate — note that PWM speed control via the 4th pin is not available, as speed is controlled by the hub's voltage switch instead.
Q: What power connectors can I use to power this fan hub?
A: The hub accepts both SATA and Molex (4-pin large) power connectors from your PC's power supply, giving you flexible installation options regardless of your PSU's available cables.
Q: Will the low-speed setting work with all fans?
A: Not necessarily. Low-speed mode supplies 5–7V to your fans. Some fans require a minimum of 12V to start spinning. If your fan does not support low-voltage startup, it will remain stationary in low-speed mode. Always check your fan's minimum start voltage in its specifications before use.
Q: How do I mount the fan hub inside my PC case?
A: The PCB has a 3M adhesive pad on the back, allowing you to stick it securely to the interior of your PC case without any screws or brackets. Simply clean the surface, peel the backing, and press firmly for a solid hold.
Q: Is this fan hub suitable for mining rigs?
A: Absolutely. The 1-to-8 expansion capability makes it a popular choice for mining rigs and multi-GPU systems that require several fans running from a single power connection, keeping build complexity and cable runs to a minimum.
