Often these air devices are referred to as PTC Fin Heaters. \$\begingroup\$ It depends on the heating element and the resistor. This effect can be used to protect circuits or devices against overcurrents. Resistors come in many shapes and sizes and have datasheets which rate the temperature it will reach with 'x' amount of current passing through it. This type of PTC heating element has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant temperature and power saving electric heater. These materials have a critical temperature where the resistivity changes quite markedly. PTC heating elements have a large positive temperature coefficient of resistance, which means if a constant voltage is applied, the element produces a large amount of heat when its temperature is low, and a smaller amount of heat when its temperature is high. By using a 470 Ohm or 1k Ohm PTC thermistor, perhaps in series with a normal resistor for fine-tuning the current flow, you can limit power to an LED.
