1. A computer-implemented method comprising:
- determining a temperature of air entering an enclosure;
determining a current draw of an electrical component within the enclosure; and
adjusting, based on the determined temperature and the determined current draw, a speed of a fan within the enclosure to change an airflow over the electrical component.

Abstract
Indirect thermal fan control is described. In one or more implementations, a speed of a fan may be adjusted based on indirect measurements of temperature. For example, a temperature of air entering an enclosure and a current draw of an electrical component within the enclosure may be determined. A speed of a fan may then be adjusted based on the temperature of the air and the current draw of the component to change a flow of the air over the electrical component.
