Frequently Asked Questions
Q: How many fans can I connect to this PWM fan hub splitter?
A: The OULLX 5-in-1 PWM Fan Hub supports up to five fans simultaneously — one dedicated CPU fan port and four standard PWM fan ports (FAN1 through FAN4). All five are powered independently via the Molex connector.
Q: Does this fan hub reduce strain on the motherboard fan headers?
A: Yes. Because the fans are powered directly by the PSU through the 4-pin Molex connector rather than the motherboard headers, the hub significantly reduces the electrical load on your motherboard, which helps extend its working life.
Q: Will I still have PWM speed control with this splitter hub?
A: Absolutely. The hub includes a 4-pin signal line that connects to your motherboard's fan header, allowing full PWM speed control and adjustment across all connected fans — giving you precise, quiet airflow management.
Q: What fan connector types are compatible with this hub?
A: This hub is compatible with standard 3-pin and 4-pin PWM fan connectors. The power is supplied via a large 4-pin Molex connector from your PSU, while the signal line uses a standard 4-pin motherboard header connection.
