A regular vacuum isn't doing anything with ions or high voltages. Moving air can generate potentially harmful static electricity, but usually the reason people recommend against vacuuming a PC is because if you spin the fans doing that, the motors inside turn into generators and drive current back into your PC parts that could damage them.
Well, and what do you think creates that static electricity? Ionization.
Feeding back electricity, that's why motors usually have a diode or something.
The difference between a vacuum and this fanless cooling device is that a vacuum happens to generate a small amount of static, and usually has grounding wires in the hose to prevent it shocking things, while this fanless device is intentionally ionizing as much air as possible to get it to move.
Exactly, that's why i'm wondering how it is save.
