Abstract
A method for detecting a cooling element type includes determining a quantity of cooling elements for a computing device. Each of the cooling elements is of a cooling element type. The method includes causing each cooling element to operate at a test pulse width modulation ('PWM') value. Each cooling element is controlled using PWM. The method includes measuring a total current draw of the cooling elements and comparing the total current draw to each of a predicted current draw at the test PWM value of a quantity of cooling elements of a particular cooling element type. The quantity of cooling elements of each of the cooling element types matches the determined quantity of the plurality of cooling elements. The method includes determining, based on the comparing, whether each of the plurality of cooling elements are of a same cooling element type or are of a mixture of cooling element types.
