Artec Peltier Cooling Neck Fan Instant Cooling Thank you for viewing. (Please take a look at my profile for your peace of mind) Used a few times, and there are small scratches on the aluminum plate of the neck cooling part (see photo 2), but there are no problems with the operation! I am selling this because I purchased a new one. Double cooling with a cooling plate at the neck and neck fan airflow, which is a great measure against heatstroke.
