Your undervolt is working correctly. What are you expecting to see change?
Your screenshot only shows a maximum temperature of 63°C. How hot is your 4700MQ getting? Many recent laptops run constantly at over 90°C when playing games. Intel considers any temperature under 100°C to be a normal operating temperature.
When was the last time you opened up your laptop and cleaned it out and replaced the thermal paste? Changing the voltage is not going to solve an overheating problem if your laptop is a mess inside.
Check the ThrottleStop Log File box. Go play a game for 15 minutes and show me a log file when you are done. This is a better way to see if there is an actual overheating problem.
