Entropy FC3

The companion app for the Entropy Radiator FC3 dual radiator fan controller. Connect over Bluetooth and set up both fans from your phone. LIVE DATA • Watch coolant temperature update in real time. FAN CONTROL • Set the start and full-speed temperature for each fan with a range slider, or tap a value to type it in exactly (130–220 °F). • Pick your fan model from presets, such as Entropy's HPX fans, to apply the right PWM frequency and polarity in one tap. The preset list updates automatically. • Fine-tune the PWM frequency (10–1000 Hz) and invert the PWM signal for each fan. FAN OVERRIDES • Force either fan to full speed for testing, with a safety check to confirm the blades are clear before it starts. SETTINGS • Read the controller's current settings into the app, or write your changes back with one tap. DEMO MODE No controller yet? Explore every screen in demo mode with a simulated controller. Nothing is sent to real hardware. Requires an Entropy Radiator FC3 fan controller for normal use.
