Abstract
Systems, methods, apparatuses for fan type identification are disclosed. A predetermined pulse width modulation duty cycle is used to obtain a sequence of fan speeds from a fan over a time period. A fan type of the fan is determined based on the sequence of fan speeds.
Claims16
A computing device comprising:
- a controller coupled to a fan and configured to:
- use a predetermined pulse width modulation duty cycle to obtain a sequence of fan speeds from the fan over a time period;
- and
- determine a fan type of the fan based on each of the fan speeds within the sequence of fan speeds.
