will turning on vsync help gpu and cpu heat ? (2024)

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 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.
