Hey! I've faced a similar issue with my RedmiBook 14. The thermal throttling started after about six months, even though everything seemed fine before. When gaming, the GPU temperature stays low—around 64°C—while the clock speeds drop sharply once it hits that mark. It's confusing because I thought 64°C was ideal. Also, I noticed CPU temps rising to 80°C and then spiking to 97°C when the GPU throttles. I restored Windows recently, but it seems drivers weren't the cause. What might be going on?
Are the vents open and the fan operating? Review your fan curve to see how it responds to temperature changes or clean it if needed. When using it while gaming, place it on a hard surface like a desk—avoid blankets or cushions that might trap heat. Quick temporary solutions: lower GPU voltage to reduce heat without sacrificing performance properly, and consider using a cooling pad. Note: If repairs are necessary, contact support as it should still be covered under warranty.
Checking the fan curve varies by motherboard model. You can find it in the BIOS settings or manufacturer documentation. Since you're using a hard desk without a cooling pad, consider adjusting GPU settings first. Undervolting might help stabilize performance. Regarding GPU clock speeds dropping when CPU overheats, yes—it usually happens because thermal throttling limits both components, causing them to run slower together.
