I live in an old house. When weather permits, I work in the detached garage.

When doing some AI stuff on my garage PC (4060 Ti; nothing crazy) the overhead lights in the garage slightly but noticeably dim. This doesn't occur when gaming.

It's most easily noticeable with one of nVidia's demo apps -- "AI Paintbrush" or something like that, I forget. It's a GUI app where you can "paint" with the mouse cursor. When you depress the mouse button, the GPU engages... and the garage lights dim. Release the mouse button, and the lights return to normal.

> You can hear some modern GPU/CPUs (well really their power electronics) when they get heavily loaded!

I'd hope you hear their fans too...

Sure, but that has a resolution of seconds at best. The coil whine in the power electronics is milliseconds-accurate.

Yeah I get a nice reminder to limit frame rates when I hear the atrocious coil whine from my 4090 as it renders 1500fps of a static loading screen.

First world problems.
