DC 12V PWM Speed Controller 4-Pin Fan Speed Governor Type-C USB 4-Wire Boost Power Module DIY Water Cooling for PC CPU Fanpump

Features:1. Supports standard 4-wire PWM protocol, compatible with mainstream motherboard fan control2. Plug-and-play with no wiring required, suitable for various power supply scenarios3. 0–100% stepless PWM adjustment, precisely balancing silence and cooling performance4. High-efficiency boost conversion with 85%–90% efficiency for more stable operation5. Compact and silent design, ideal for DIY modifications and silent PC optimizationProduct 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 ControllerInput Voltage: 5VOutput Voltage: 12VPWM Frequency: Approx. 25KHzOutput Current: Rated 0.5A, Maximum 0.7AInput Port: USB Type-C FemaleOutput Port: PWM 4-Pin (KF2510)Speed Control Range: PWM Duty Cycle 0-100%Package include:Speed Controller Module *1
