    I´ve noticed that when Shadowplay active, it lowers the temp while on desktop of both the GPU and CPU.
    Anyone else noticed this?

    .... I... wut. I'm trying, but this makes no sense in my brain. If your FPS remains the same and it's recording and your temps are DROPPING, then that's either one jesus computer you've got or it's aliens

    With Shadowplay active I don´t mean the recorder of Shadowplay, but putting the service of Shadowplay on active in GeForce Experience preferences menu while on desktop. And then check your temperature meter drop slightly.

    Could possibly limit FPS or force some form of vsync which would result in lower temps.

    That's what I was thinking. This is the only thing I can think of ShadowPlay doing. I think it forces 30 FPS or something.

    ShadowPlay recording drops GPU usage slightly, and since your laptop has a single fan, this will drop temperatures on both GPU and CPU.

    My guess is that Shadowplay uses the otherwise-unused CUDA functionality to record gameplay, and turning it on actually powers down those parts of the GPU when not recording. That's the only thing I can think of, really, but since it's the prime reason behind Maxwell's advancements (though on a larger scale, I think)... then =D.

    Could it be you're streaming to a less resolution machine? Like Shadowplaying to a 720p resolution would indeed lower your temps as the GPU has a far easier time rendering less resolution.

    He stated that he is not actually recording. He is simply "enabling" shadowplay to be active in GeForce Experience, and that has dropped his temperatures. His temps while recording are not what he's talking about, which is why I was confused.
