DC 12V 5A PWM Fan Temperature Speed Controller Module

DC 12V 5A PWM Fan Temperature Speed Controller Module

Take precise control of your cooling system with this DC 12V 5A PWM Fan Temperature Speed Controller Module. Designed for PC builds, DIY electronics projects, and industrial enclosures, this compact module automatically adjusts fan speed based on real-time temperature readings — keeping your components running efficiently and quietly.

Key Features

• PWM Speed Control: Smoothly regulates fan speed via Pulse Width Modulation for accurate, stepless adjustment
• Automatic Temperature-Based Control: Uses an NTC B-3950 thermistor (50K) to sense ambient or component temperatures and adjust fan speed accordingly
• High-Temp Buzzer Alarm: Built-in buzzer triggers an audible alert when temperatures exceed a set threshold — helping you monitor your system proactively
• Stall Alarm: Minimum speed stall detection activates at 700–800 RPM, alerting you if the fan stops spinning unexpectedly
• DC 12V / 5A Rating: Compatible with standard 12V DC fans up to 5A load capacity
• SMD Construction: Surface-mount device design for reliability and compact integration
• Customizable Settings: Adjustable temperature thresholds to suit your specific cooling requirements
• Available in 2 color options — order as a single unit (1 pc) or a value pack (5 pcs)
