GPU Undervolting Guide — Run Cooler and Quieter for Free

Cartoon RTX-style graphics card with a downward voltage curve graph and green temperature gauges indicating reduced temperatures from GPU undervolting.

GPU undervolting costs nothing, takes 30 minutes, and drops GPU temperatures by 10 to 20 degrees while making your card quieter and extending its lifespan. Your GPU ships at a conservative voltage to guarantee stability across all manufacturing tolerances. Undervolting finds the lowest voltage at which your specific card can stably run at its target clock speed. Less voltage means less power, which means less heat — at the same performance level. Pair undervolting with fresh Thermal Grizzly Kryonaut for drops of 20 degrees or more. Read the full guide.
