WhisperMode is a proprietary NVIDIA technology that makes your plugged-in laptop run much quieter while gaming. It works by intelligently pacing the game’s frame rate while simultaneously configuring the graphics settings for optimal power-efficiency.
NVIDIA WhisperMode reduces fan noise from laptops while still providing an excellent gaming experience. This is achieved through the intelligent pacing of frame rates and efficient selection of game settings.
Combined, these methods reduce the amount of heat generated by the GPU which reduces the amount of heat that a laptop must dissipate. This means that the laptop fans can run at lower speeds and produce less noise – resulting in a more pleasant gaming experience for you, and anyone else in earshot.
