Just read arshia mentioned 3.9ohms per coil. Then coil current would go to ~3amps. Quickfix could try 5v psu for the motors, something like an atx 5v line. Then current would go to 5v / ~4ohms = 1.25A which should be manageable and less heat. But still a 1.25A current would make quite some heat and we dont know how high the motor is rated (what does it say on the label?). If heat is too much, then could even try use the 3.3v line, who knows maybe that would work better with current to less than 1A.
