var smc = require('libsmc');
 
var number = smc.getNumberOfFans();
// => 2

smc.getFan(number)

Gets the information related to a specific fan. number is a positive integer unique to that fan, starting at 0. Returns an object of format { name, speed }, where name is the given name from the machine, and speed is the RPM (rotations per minute) of the fan at that point in time.

var smc = require('libsmc');
 
var fan = smc.getFan(0);
// => { name: 'ExhaustZ', speed: 2176 }
