Method for independent processor cooling in desktop PCs

Disclosed is a method for independent processor cooling in desktop PCs. Benefits include improved thermal performance, improved performance, and improved design flexibility.

Background

      As processor power continues to increase, meeting thermal requirements becomes increasingly important. The maximum processor power that conventional desktop thermal designs can accommodate is about 75W.

              Conventional desktop PC cooling is primarily a two-dimensional flow along the motherboard plane. Separation of processor cooling from system cooling is not possible without ducting, which increases airflow resistance. High cooling efficiency using a processor heatsink is not possible because two-dimensional flow requires longer airflow path. One conventional solution is a remote heat exchanger.

Description

                            The disclosed method is independent processor cooling in desktop PCs. Three-dimensional system airflow is created by a remote heat exchanger and a side-to-side airflow path (perpendicular to the plane of motherboard) for processor cooling. A power supply fan induces airflow parallel to motherboard for components cooling (see Figure 1).

              For larger systems, an additional fan, which would have been required for venting processor exhaust, is no longer required.

              For smaller systems, the power supply fan can be dedicated for system components cooling.

              The key elements of the...
