Using drivers like OpenLibSys or WinRing0 , the process constantly polls CPU, GPU, and motherboard temperature sensors. This data determines how aggressively the fans should spin.
| Module | Responsibility | |--------|----------------| | | Handles command‑line arguments ( -speed , -color , -anim ). The optional GUI (built with WinForms/WPF) forwards the same commands. | | FanControl.dll | Low‑level wrapper around Windows SetupAPI / WinRing0 to toggle PWM duty cycle (0‑100 %). | | LED Engine | Implements the timing‑critical data stream for WS2812/APA102 LEDs using the CreateFile + WriteFile API on the fan’s data line (exposed as a virtual COM port or direct GPIO via the motherboard’s SMBus). | | Script Engine | Embedded Lua interpreter ( lua5.4 ) that lets users write custom scripts like if cpu_temp > 70 then set_color(255,0,0) end . | | Event Monitor | Polls system sensors via OpenHardwareMonitor or WMI and fires events ( TEMPERATURE_CHANGE , CPU_LOAD , AUDIO_PEAK ). | ledfanexe work
| Function | Parameters | Description | |----------|------------|-------------| | set_speed(percent) | 0‑100 | Directly set PWM duty cycle. | | set_color(r,g,b) | 0‑255 each | Apply a solid color to LEDs. | | set_pixel(i, r,g,b) | i = 0‑(N‑1) | Set an individual LED (useful for strips). | | set_gradient(startColor, endColor) | r,g,b tables | Smooth gradient across the whole strip. | | get_temp() | – | Returns current CPU temperature in °C (float). | | get_load() | – | Returns CPU usage percent. | | on(event, func) | event = "temp", "load", "audio" | Register a callback. | | sleep(ms) | – | Pause script execution (non‑blocking). | Using drivers like OpenLibSys or WinRing0 , the
