System for parallel cooling of components on a circuit board
A cooling system for cooling a set of components on a circuit board includes a vapor chamber for distributing heat over a larger surface area, a fan in a housing configured to direct a first airflow in a first direction to a first heatsink and direct a second airflow in a second direction opposite the first direction to a second heatsink. The heatsinks can have different sizes and the fan can be located relative to a midpoint of the vapor chamber or the circuit board or positioned relative to a component on the circuit board.
