Power supply unit with consolidated different airflow direction fans

A power supply unit comprising:

• a main portion including a cooling fan slot;
• a dual direction cooling fan inserted within the cooling fan slot of the main portion, wherein the dual direction cooling fan is inserted in the cooling fan slot in a reverse airflow orientation or in a normal airflow orientation, the dual direction cooling fan includes:
• a first panel positioned toward a middle line of the main portion when the dual direction cooling fan is inserted within the cooling fan slot;
• a second panel positioned toward an outside edge of the main portion when the dual direction cooling fan is inserted within the cooling fan slot;
• a third panel that extends perpendicularly the between first edges of the first and second panels, wherein the third panel is positioned toward a top panel of the main portion when the dual direction cooling fan is in the reverse airflow orientation;
• a fourth panel that extends perpendicularly between second edges of the first and second panels, wherein the fourth panel is positioned toward the top panel of the main portion when the dual direction cooling fan is in the normal airflow orientation;
• and
• connector pins on the first panel, wherein the connector pins include a first row and a second row, wherein a pin in the first row has an opposite voltage as compared to a corresponding pin in the second row, wherein the connector pins receive power and pulse width modulated signals for the dual direction cooling fan.

An information handling system comprising:

• a plurality of components including a processor and memory devices;
• and
• a power supply to provide power to the processor and the memory devices, the power supply includes:
• a main portion including a cooling fan slot;
• a dual direction cooling fan inserted within the cooling fan slot of the main portion, wherein the dual direction cooling fan is inserted in the cooling fan slot in a reverse airflow orientation or in a normal airflow orientation, the dual direction cooling fan includes:
• a first panel positioned toward a middle line of the main portion when the dual direction cooling fan is inserted within the cooling fan slot;
• a second panel positioned toward an outside edge of the main portion when the dual direction cooling fan is inserted within the cooling fan slot;
• a third panel that extends perpendicularly to between first edges of the first and second panels, wherein the third panel is positioned toward a top panel of the main portion when the dual direction cooling fan is in the reverse airflow orientation;
• a fourth panel that extends perpendicularly to between second edges of the first and second panels, wherein the fourth panel is positioned toward the top panel of the main portion when the dual direction cooling fan is in the normal airflow orientation;
• and
• connector pins on the first panel, wherein the connector pins include a first row and a second row, wherein a pin in the first row has an opposite voltage as compared to a corresponding pin in the second row, wherein the connector pins receive power and pulse width modulated signals for the dual direction cooling fan.
