Silver dollar experience, confirmation?

macOS & Mac Apps
Hi all. I've recently played Silver dollar, and have noticed something odd. Especially when I shoot the plates out of the air, my fan goes nuts. I wondered if maybe it should do that, or if because i'm heavy with the keyboard it does that. does anyone else have this? I didn't notice it anywhere but that part of the game, but I didn't pick up on this until last night. Here's to more shooting and hoping they come out with a longer game like the old grizzly gulch for windows years ago.
