GPU undervolting isn't worth the hassle: Set a power limit to drop temps in seconds

A GPU undervolting approach may be unnecessary for many users, the article argues, and a simpler power limit can deliver similar benefits quickly. It explains undervolting as reducing GPU voltage until it fails, then adjusting back to stable settings—often requiring trial and error despite being generally low risk. Because power relates to voltage and current, undervolting can reduce heat and noise and may even improve boost behavior by easing thermal throttling. However, for desktop systems, setting a GPU power cap can be easier since modern GPUs manage voltage and frequency within the limit. The piece notes that a 90% cap doesn’t automatically mean a 90% performance drop.
