Delinx USB 5V to 5-12V Fan Speed Controller – Your Ultimate Cooling Control Solution Tired of noisy, full-speed fans ruining your gaming or work experience? Struggling with limited motherboard fan headers or bulky power adapters for your cooling projects? The Delinx USB 5V to 5-12V Adjustable Fan Speed Controller is here to solve all your cooling pain points with a simple, versatile, and user-friendly design. ✅ Universal Compatibility for All Your Cooling Devices This controller supports stepless speed regulation for 2Pin, 3Pin, and 4Pin 12V cooling fans, as well as water pumps and devices with a 5521 DC barrel connector. Whether you’re working on a PC case build, water cooling loop, DIY air purifier, or home theater cabinet, it works seamlessly with most standard 12V fans and pumps on the market. ✅ USB-Powered Freedom, No Extra Cables Needed Powered by any standard USB 5V port (wall chargers, power banks, PC USB ports, or laptops), this controller eliminates the need for dedicated AC adapters. The 4.8FT (146cm) total cable length provides plenty of flexibility for installation, while the included 30cm DC5521-to-4Pin fan adapter ensures you can connect to your devices right out of the box. ✅ Precise Control, Total Customization The large, ergonomic adjustment knob lets you fine-tune speed levels from near-silent low speeds to full 12V maximum airflow, while the dedicated on/off switch lets you cut power completely without unplugging devices. This means you can easily balance cooling performance, noise levels, and power consumption to match your exact needs. ✅ Built for Safety and Reliability With over-voltage, over-current, and short-circuit protection, you can trust this controller to keep your fans and pumps safe from damage. The durable, heat-resistant cable and high-quality components ensure long-lasting performance, even in high-use environments like gaming PCs or 3D printer enclosures. ✅ Endless Applications Perfect for: PC case cooling and gaming rig builds Water cooling pump speed control DIY air purifiers and ventilation systems Router and modem cooling Home theater and cabinet ventilation 3D printer and electronics enclosure cooling Any DIY project requiring adjustable 12V fan/pump control Specifications: Input Voltage: DC 5V (via USB Type-A) Output Voltage: DC 5V-12V adjustable Max Output Power: 6W Cable Length: 146cm/4.8FT total, 30cm fan adapter Compatible Devices: 2Pin/3Pin/4Pin 12V fans, 12V water pumps, 5521 DC devices Package Includes: 1 x Delinx USB 5V to 5-12V Fan Speed Controller 1 x 30cm DC5521 to 4Pin Fan Adapter Cable Review: Didn't fit my needs, but product stems good.

Super easy way to tap power from usb port to power a 12V computer fan. I use it to control a PWM fan and it works really well, allowing me to adjust full spectrum of speeds.

Now I can control and power a standard PC fan from a regular USB port. It's useful for my little DIY project. And actually there are not many alternative products...

This is currently powering two fans venting heat from a recessed fridge and been running great for the past 4 months.
