[Amps] Fan for SB220

[Adrian]

To further prove my point, you have a black car and a white car out in 
the sun on a hot day.
You know the black car is going to be hotter, but why is this when black 
is apparently such a good radiator that it should just radiate all that 
excess heat right out of that car, as quick as its absorbing it?.

Because its not a good radiator, but it pretty good at absorbing the 
sunlight radiated heat  increasing the temperature within. The surface 
temperature is damn hot and when you drive the black car down the road, 
the air passing over the car cools it down due to COVECTION.

Things don't radiated of their own accord without a energy source, and 
there is a colour spectrum for different types of radiation, ie: infra 
red which you see from the 3-500z is radiated heat, white light 
composing all the colours within of various luminous wavelengths. Ultra 
violet etc, the list goes on.

Please let me know what the wavelength is of radiated heat from black?

convection
the act of conveying or transmission; specifically, transmission of heat 
in a liquid or gas by circulation of heated particles
