Review on Portable Neck Fan - Hands Free Bladeless, 4000MAh Battery Operated Wearable Personal Cooling With 3 Speeds & Turbo Motors, USB Powered Hanging Fans (White) by Sam Calderon

There are settings to give you the draft that you need for your circumstance. Of course in hot conditions, the air blows warm air but at least you have circulation where you need it. I sweat from my face and head but the neck device keeps me comfortable.The device does not generate heat. It makes minimal noise even with the wind at your ears.
