my screen fails when playing video

For some reason my screen fails when playing videos. It doesn't do it every time and tends to be when the video is played in full screen or Theater mode on youtube. I imagine it's something to do with the graphics card or something?

Any ideas?

Thanks

iMac 27″, macOS 12.6

Have you blown the dust out of the intakes lately?

What temperatures does this App report? Especially the GPU.

This App can be used to speed up the fans, all my iMacs would be dead without it.

Never ever ever drop fan speeds below the speed that the Mac itself is calling for.
