PredatorLite – Lightweight, safety-first open-source alternative to PredatorSense (currently for PHN16-71)
Hey everyone,
I’ve been working on an open-source alternative to PredatorSense called PredatorLite.
It’s a lightweight, safety-gated control utility for Acer Predator laptops on Windows 11. The goal is to give users proper control over performance modes, fans, GPU switching, lighting, battery charge limit, and monitoring — without the bloat and with much stricter safety boundaries.
Currently verified
- Acer Predator PHN16-71
- BIOS V1.20
- Windows 11 24H2 (build 26100+)
On other models it runs in read-only/diagnostic mode. Hardware writes are only enabled on verified profiles.
Main features
- Performance modes: Quiet / Balanced / Performance / Ultra / Power Saving
- Fan control: Auto, Full Speed, and custom temperature curves
- GPU Hybrid ↔ Discrete switching (with restart prompt)
- 80% battery charge limit
- Keyboard & logo lighting (4-zone)
- System tray + OSD + global shortcuts
- Real-time monitoring (CPU/GPU temps, fans, battery, etc.)
- Multilingual (Chinese / English)
Safety design (important)
- No overclocking, no voltage control, no power limit unlocks, no MSR/NVAPI abuse
- All write operations are gated by explicit hardware profiles
- Runs with standard user privileges
- FanGuard watchdog that restores fans to Auto if the main app crashes
- No silent background rewriting of settings on startup
It works with the official Acer services instead of trying to replace them.

It’s still early (MIT licensed). I’m mainly looking for:
- Feedback from other PHN16-71 owners
- Bug reports
- Suggestions for additional verified models (if you have protocol evidence)
If you try it, please let me know how it behaves on your machine. Happy to answer any questions.
Thanks!
