DC 5V to 12V PWM Fan Controller 4Pin 0-100% Adjustable Speed Regulator Type-C Input for PC Cooling DIY Water Cooling System Features 1. Supports standard 4-wire PWM protocol, compatible with mainstream motherboard fan control 2. Plug-and-play with no wiring required, suitable for various power supply scenarios 3. 0–100% stepless PWM adjustment, precisely balancing silence and cooling performance 4. High-efficiency boost conversion with 85%–90% efficiency for more stable operation 5. Compact and silent design, ideal for DIY modifications and silent PC optimization Product Description The PWM controller features a USB Type-C input and a 4-pin mini-PWM fan output. It incorporates a built-in DC-DC boost circuit that steps up 5V to 12V. Speed control is achieved by outputting a PWM signal. Due to losses in the built-in boost circuit (efficiency approximately 85%), excessive output current will result in significant heat generation. It is recommended to keep the output current below 0.5A, though it can reach 0.7A for short periods. Parameter Product Name: PWM Speed Controller Input Voltage: 5V Output Voltage: 12V PWM Frequency: Approx. 25KHz Output Current: Rated 0.5A, Maximum 0.7A Input Port: USB Type-C Female Output Port: PWM 4-Pin (KF2510) Speed Control Range: PWM Duty Cycle 0-100%
