A native macOS fan control utility built with Tauri v2 (Rust backend) and Svelte 5 (frontend). Monitor temperatures and manage fan speeds through Apple's System Management Controller (SMC).
Beta — This app is in active development. Please report issues on GitHub.
- Real-time temperature monitoring via SMC and IOKit sensors
- Per-fan speed control: automatic, constant RPM, or sensor-based curves
- TestFlight/App Store build path with sandboxed monitoring-only behavior
- Menu bar tray with live CPU temperature display
- Custom preset save/restore
- Emergency thermal override safety system
- Light and dark mode (follows macOS system appearance)
- macOS 13 Ventura or later (Intel or Apple Silicon)
- Fan speed control requires running as root — the app will prompt on first use
Download the latest .dmg from Releases. Release builds are Developer ID signed and notarized by Apple, so macOS Gatekeeper accepts them on first launch.
