01.Heat: The Gaming Laptop's Enemy
2026 gaming laptops are powerful, but the laws of physics don't change. Having a 14 or 24-core processor in a 2cm space generates absurd heat. When the processor reaches 95°C, it enters **Thermal Throttling**, cutting its speed in half to avoid melting. **Undervolting** consists of finding the lowest stable voltage for your processor, making it consume less power and generate less heat, while maintaining the same FPS.

02.1. Unlocking Undervolting in 2026
Attention: Intel and AMD have blocked undervolting on many recent models for security reasons (Plundervolt):
Before starting, check if your processor allows voltage changes. In 2026, many manufacturers require you to enable an option like 'Overclocking Feature' in the BIOS for software like ThrottleStop to work. If the voltage sliders are grayed out (locked), you will need to research if your specific laptop model allows unlocking via BIOS.
03.2. Using ThrottleStop (Step-by-Step)
Safe Procedure:
1. Open ThrottleStop and click on FIVR.
2. Check 'Unlock Adjustable Voltage'.
3. In 'Offset Voltage', start with -50mV.
4. Apply the same voltage in 'CPU Core' and 'CPU Cache'.
5. Increase by 10 (e.g., -60mV, -70mV) and run a stress test. If the PC freezes or blue-screens, you've hit the limit. Go back 10mV, and that will be your ideal performance point.
04.3. Why Isn't This Dangerous?
Unlike Overclocking (which increases voltage and risk), Undervolting **decreases** stress on the processor.
Tip: In 2026, a processor that runs at 80°C will last many more years than one that constantly works at 100°C. The only "danger" is the PC freezing and restarting, but this doesn't cause hardware damage and serves only as a warning that you reduced the voltage too much.
