Key Functions for the PH315-51:

• Cooling Control: Manages the dual-fan system. You can switch between Auto, Maximum, and Custom fan curves.
• Performance Tuning: Adjusts power limits for the CPU (Intel Core i7-8750H or i5-8300H) and GPU (NVIDIA GTX 1060 or 1050 Ti).
• RGB Keyboard Customization: Controls the backlit 4-zone RGB keyboard (red-backlit models also use this for basic on/off).
• Monitoring: Real-time tracking of CPU/GPU temperature, clock speeds, and fan RPM.
• Power Plans: Switches between Default, Balanced, and High Performance power profiles linked to Windows power options.

Without Predator Sense, your cooling fans will default to a safe but noisy curve, you cannot control the RGB lighting, and you lose the ability to undervolt or overclock your GPU. In short, your Helios 300 becomes a standard office laptop.
