You might try NVIDIA nTune :
NVIDIA® nTune is the ultimate utility for accessing, monitoring, and adjusting your system components, including temperature and voltages with clear, user-friendly control panels. Overclock your system for highest performance or underclock it for near silent operation. All changes are performed within the Microsoft® Windows® interface – enabling full functionality without the need to make changes in the BIOS and reboot your system.
I prefer nvidiaInspector, because it has a great overview about the most important sensor data and a clean, minimalistic interface. Also you can create desktop shortcuts for different Profiles for fast switching between configurations.
