Micro Cooling Fan radiator selection

"Micro Cooling Fan" under the air-cooled heat sink selection is actually the case for the purposes of a particular system, you can have all kinds of radiator solution, you can choose a small radiator under a large air velocity conditions can also choose large radiator airflow velocity smaller work environments. The higher the air velocity, the greater the noise generated by a fan, but these drawbacks can be obtained by a small system size to compensate. "Micro Cooling Fan" It is worth noting: When the flow rate is greater than 7m / s, almost never to reinforce the cooling effect. When the system power is only required cooling equipment, you can also use a radiator with a fan. In the case of forced convection, natural convection heat sink selection and lower radiator selection method is similar. Although the fluid (air) temperature determines how much of the thermal resistance is important, but the main factor is not an option "Micro Cooling Fan" radiator, air velocity is the only choice radiator (with substrate size to match the radiator) heat
