The present invention is directed to ventilating or cooling element for airflow cooling in a digital data processing apparatus, and it is particularly suited to such apparatus having a high circuit density, or mounted within a restricted chassis or housing, such as the housing of a web server, or of a storage array device for a network server or web server. The cooling element includes a fan that is disposed at an angle to integrate its cooling air with general circulation or air flow through the chassis. The element may mount on a plate, such as the thermally conductive plate of a heat sink, that is adapted for coupling to the chassis and/or contacting a microprocessor chip, and a fan is disposed on the mounting plate at an angle to cool the plate or chip without creating obstructive cross wind. The mounting plate can be disposed within the middle portion of the chassis. The fan or cooling element can be angled so as to direct airflow towards at least a selected portion of the chassis, e.g. along a flow path to a chassis vent or opening, which may be in the rear portion. The mounting plate can also include one or more a thermally conductive heat dissipation members, such as fins or posts, and the fan may have a side-to-side tilt as well as an inclination with respect to the plane of the plate.

A digital data processor comprising a chassis, a circuit component disposed in the chassis, any of an intake fan and an exhaust fan (collectively, "intake fan") that is disposed on or in the chassis and that provides cooling airflow within chassis, a cooling element for cooling at least the circuit component, the cooling element comprising a heat sink that is mounted on the component and a fan that is mounted on the heat sink, the fan being disposed at an oblique angle relative to a plane of the component such that allow generated by the fan is integrated with cooling airflow provided in the chassis by the intake fan. 2. The digital data processor of claim 1, wherein the chassis has a front portion, a middle portion, and a rear portion, the intake fan provides cooling air-flow within the chassis that circulates in a direction of the rear portion of the chassis, and the fan of the cooling element is angled to also generate airflow in the direction of the rear portion of the chassis. 3. The digital data processor of claim 1, wherein the fan of the cooling element is angled such that airflow generated by it is channeled any of (i) to heat-sensitive components or (ii) to divert airflow around an obstructing component. 4. The digital data processor of claim 1, wherein the heat sink comprises at least one thermally conductive heat dissipation member disposed on a mounting plate. 5. The digital data processor of claim 4, wherein the at least one conductive member comprises a plurality of spaced apart fins. 6. The digital data processor of claim 4, wherein at least one conductive member comprises a plurality of spaced apart posts. 7. A cooling element for use in a digital data processor apparatus, the cooling element comprising: a thermally conductive mounting plate for mounting on a circuit component of the digital data processing system; a fan disposed on the mounting plate, the fan being disposed at an oblique angle relative to a plane of the mounting plate such that air flow generated by the fan is integrated with a direction of cooling airflow within a chassis of the digital data processor apparatus in which the circuit component is disposed, a plurality of thermally conductive heat dissipation members disposed on a mounting plate. 8. The cooling element of claim 7, wherein the heat dissipation members comprise a plurality of spaced apart fins. 9. The cooling element of claim 7, wherein the
