Designed for chassis, computer, and CPU cooler fans, this compact STK IC module delivers precise temperature‑based speed regulation, quieter operation, and reliable protection against overheating.

Key Highlights

  • ✅ 12 V / 0.8 A PWM control – smooth, silent fan speed adjustments.
  • ✅ 2‑wire or 3‑wire compatibility – works with most standard PC fans.
  • ✅ Built‑in temperature sensor for real‑time fan speed tuning.
  • ✅ STK IC technology ensures stable operation and low power consumption.
  • ✅ Alarm function alerts you when fan speed drops or temperature spikes.
  • ✅ Compact, plug‑and‑play design – no soldering required.

Why Choose This Fan Speed Controller?

Maintaining optimal airflow is critical for system stability and longevity. This controller intelligently matches fan speed to the actual temperature inside your chassis, reducing noise when cooling demand is low and ramping up power when needed. The result is a quieter, cooler, and more energy‑efficient computer.

Features & Benefits

  • Dynamic PWM Regulation: Adjusts fan RPM from 0 % to 100 % based on temperature thresholds you set.
  • Noise Reduction: Lower fan speeds during idle periods dramatically cut acoustic output.
  • Thermal Protection: Prevents overheating of CPUs, GPUs, and other components.
  • Easy Installation: Connect the fan’s power leads to the controller’s 2‑wire or 3‑wire terminals and plug the controller into a 12 V supply.
  • Universal Compatibility: Works with most 12 V DC fans used in desktops, workstations, and small form‑factor builds.
  • Built‑in Alarm: Visual or audible alert when fan fails or temperature exceeds safe limits.

Technical Specifications

  • Input Voltage: 12 V DC
  • Maximum Current: 0.8 A
  • PWM Frequency: 25 kHz
  • Wire Options: 2‑wire (power only) or 3‑wire (power + tachometer)
  • Operating Temperature: –10 °C to +85 °C
  • Dimensions: 30 mm × 20 mm × 10 mm
  • Connector Type: Standard 2‑pin/3‑pin fan header

Installation Guide

1. Power off your PC and locate an available 12 V fan header.
2. Connect the fan’s red (+) and black (–) wires to the controller’s corresponding terminals.
3. If using a 3‑wire fan, attach the tachometer wire to the controller’s signal pin.
4. Plug the controller into the 12 V supply or motherboard fan header.
5. Power on the system – the controller will automatically begin temperature‑based speed regulation.

Perfect For

  • Desktop and gaming PCs
  • Workstations that demand silent operation
  • Small form‑factor builds where space is limited
  • Enthusiasts seeking precise thermal management
  • Anyone looking to extend fan lifespan and reduce power draw
