Claims40
A computer system comprising:
- a system fan disposed in the computer system, the system fan operable to create an airflow path to dissipate heat within the computer system, the airflow path extending through the computer system, the airflow path operable to enter from a first side of the computer system and exit from a second side of the computer system such that the first side is opposite from the second side;
- a fanless power supply disposed in the airflow path, the fanless Power supply operable to provide electrical power to the computer system;
- the fanless power supply including at least one air ingress and at least one air egress;
- both the at least one air ingress and the at least one air egress oriented to substantially minimize airflow obstruction such that the airflow path moves in a substantially direct path through the computer system;
- and
- a first electrical connector positioned on the fanless power supply such that the first electrical connector is outside the airflow path.
