There are both advantages and disadvantages to undervolting. On the positive side, undervolting can lead to lower CPU temperatures, which translates to quieter fans and potentially improved performance due to reduced thermal throttling (CPU slowdown to avoid overheating). It can also extend the lifespan of your CPU by reducing stress and lower your electricity bill due to decreased power consumption. However, undervolting requires some technical knowledge and carries a risk of instability if done incorrectly. An unstable undervolt can lead to crashes and unexpected shutdowns. Additionally, not all CPUs are created equal, and some may not undervolt as well as others.
