Tiny Cooling Fan mains frequency is fixed

"Tiny Cooling Fan" because of the power frequency is fixed, so the rate of change of magnetic steel sheet produced is determined by the power frequency, the higher the frequency magnetic field to switch the faster, the faster the speed will theoretically, the more the number of poles as DC fan speed more principle as fast. However, the frequency can not be too fast, too fast will cause difficulty in starting. Air-cooled heat sink "Tiny Cooling Fan" fin, likely to cause greater damage to the CPU heat, unfortunately a lot of people are still using it, because come easy, many of which are complimentary. In order to accelerate the heat conduction, to suggest that you use "Tiny Cooling Fan" thermal grease. We know that no matter how solid and solid close contact, they would leave a small gap, then the heat transfer will be very slow.
