Reduce voltage on my laptop for better performance.
Reduce voltage on my laptop for better performance.
You're experiencing ongoing thermal problems despite undervolting your i7-8750H. Let's explore some adjustments. Consider fine-tuning the Core Voltage Offset and Cache Voltage Offset further, aiming for slightly higher values if needed. Also, ensure your cooling solution is adequate—consider adding a liquid cooler or improving airflow. Monitor temperatures closely and test different settings incrementally. If issues persist, check for firmware updates or hardware compatibility.
Prior to adjusting voltage, I experienced most of the high readings around +90 degrees and frequently at 95°C. After implementing undervolting, temperatures remain stable at 90-94°C. I’ve also ensured my laptop is free of dust.
When none of it did, reduce voltage a bit and halt once instability appeared. There’s no single ideal undervolt; each chip behaves differently.
Undervolting alone won't lower your temperatures, which is expected. Laptop CPUs are usually tightly limited by heat, so they'll increase speed until they hit the maximum safe temperature, then slow down just enough to maintain that level when under load. Lowering the voltage reduces heat production but still achieves the same temperature, only with less throttling. To actually cool things down, you also need to reduce performance output.
