Frequently Asked Questions
Q: What power source does this PWM fan controller use?
A: This PWM fan speed controller uses a standard USB Type-C female input rated at 5V DC. It includes a built-in DC-DC boost circuit that steps the voltage up to 12V, making it compatible with most USB Type-C power banks, adapters, or PC USB ports.
Q: Is this module compatible with standard 4-pin PWM PC fans?
A: Yes. The module outputs via a standard 4-pin KF2510 PWM header and supports the standard 4-wire PWM protocol, making it compatible with most 4-pin PWM PC fans, water-cooling pumps, and other 12V PWM accessories used in DIY PC builds.
Q: What is the maximum safe output current for this controller?
A: The rated continuous output current is 0.5A. While the module can briefly handle up to 0.7A, it is recommended to stay at or below 0.5A during regular use to prevent excessive heat buildup from the boost conversion circuit and to ensure long-term reliability.
Q: Does this require any software or driver installation?
A: No software or drivers are needed. The Gaqqee PWM speed controller module is a fully hardware-based, plug-and-play solution — just connect your USB Type-C power source and your 4-pin PWM fan or pump to get started immediately.
