if i play game with +100 fps , will it produce more heat than when i play it with vsync ?

and if yes , only gpu heat or cpu and gpu ? and does it really worth it to turn it on ? how much heat will it reduce ?

The heat is not related with the fps you get during play. It is related with the load the cpu and gpu are having.

If you are playing graphics intensive games, then the gpu and of-course the cpu, will have to process the data and the rendering, and while doing their separate jobs, they get heated up.

Now vsync is a technology which was developed to reduce tearing effect which you see while playing games.

When vsync is off, you might experience similar tearing experience in games

When vsync is turned on, those tearing effects can be reduced and smooth gaming can be experienced.

When you turn on vsync, you will get a lesser fps(than when it is turned off), but a better gaming experience.

So turning on vsync will not affect you cpu and gpu heat. So if you start an graphics related application your gpu will be used and only that increases the heat of gpu and cpu.

Using Vsync will decrease the amount of frames your card has to render, which would directly decrease the load and hence temperature of the card as well.

Hence if your card is rendering at over 100FPS, it'd be running warmer since it renders more frames than otherwise needed. Vsync would be especially recommended for older games since you really don't want to be stressing your card running them at 200FPS.

Vsync does cause mouse lag in games, but it eliminates unnecessary load off your GPU so that your framerate matches your monitor's refresh rate.

Yes, and it works well, especially if it's an older game with uncapped frame rate. For example, playing Serious Sam First Encounter HD on my rig can yield frame rates of over 300 FPS, with plenty of noise and heat, turning Vsync on stops it, quite literally, cold.

The one thing I like about Nvidia is their adaptive Vsync option in the Nvidia Control Panel, activates Vsync when it exceeds your refresh rate and disables it when it goes below
