What it does

Adjust fan speed (0–100 %) via a simple slider.
Switch between Quiet, Balanced, and Performance profiles.
Real-time telemetry (CPU/GPU temps, fan RPM) displayed in the UI.
Dark & Light theme support.
Auto-starts background hardware daemon silently.
Safe, reversible EC/WMI writes — daemon restores BIOS control on exit.

Installation

Download the latest cremecore-setup.exe (button above, or from GitHub Releases).
Run cremecore-setup.exe and follow the setup wizard.
Launch cremecore from your Desktop or Start Menu!

Note on Fan Control (PawnIO): Direct fan speed overrides require the PawnIO driver (PawnIOLib.dll + LpcACPIEC.bin). If not already installed, obtain it from PawnIO Releases.
