I wear cotton gloves (very simple ones) for computer'ing because my hands are abnormally sweaty and I quite literally can't grasp the mouse or feel the keyboard properly otherwise. Just gallons of sweat everywhere.

Before I would make mice shiny and keyboards grimy very quickly, but since I started gloving up I've not had a single mice or keyboard die on me.

What about those little USB fans pointed at your hands?

They all died, those dinky things are not made for continuous, long-term operation. I'm pretty sure some of them fried a few ports/controllers, too.

Noctua sells 5v variants of their fans, they come with a USB adapter.

You may need to rig something to keep it upright (or at least finger safe?)
