If you want to undervolt to make your Nvidia card work less during games or any sort of GPU-intensive app, get MSI Afterburner and choose one of the options below. Note that I'm using my 1080Ti as an example.
Make a Voltage/Frequency curve with Ctrl-F. The lowest you can manually set is 800 mV, and with that I set my frequency to 1632 MHZ. This is dependent on the card type and also the specific card that you have, so start lower than those if you try this.
Slide the Power Limit downward, and it will bring the voltage and frequency down. I've seen it as low as 693 mV. This is a much easier and safer way to underclock and undervolt, though the numbers will shift around somewhat, unlike the first option.
Both of these methods will let your card run cooler and quieter in games (and it's pretty much necessary if mining cryptocurrency), and when your card is idle it'll still drop down to its idle voltage and frequency. (139 MHz and 650 mC) I recommend creating a profile for each one and testing them to see which works best for you. Test for stability too! If things crash or show visual artifacts, dial down the frequency. This is mainly an issue if you're locking at a specific voltage and frequency like in the first method. You can also mess around with the memory clock and drop as low as -502 MHz
Also make sure to cap your FPS if you're running a game that normally goes well above your refresh rate. You don't need to run Minecraft at 300 FPS. Combine that with the above methods and your card won't be doubling as a space heater.
