CrazeD just trust us, you can't cool a CPU to below room temperature with a fan.
The point of fans is to remove the heated air that surounds the heatsink and replace it with air thats at room temp, thereby allowing faster thermal transfer.
So how is it that a fan can cool my room
A fan does not cool your room unless its mounted in a vent and the air outside is below room temp.
All a desk fan does is move the warmer air that surrounds you and replace it with air at room temp.
