In at least some of the foregoing apparatus embodiments, the first strip and the second strip are shaped to resemble antiphase triangular waveforms. Additionally or alternatively, the EMI may be a first EMI with a first frequency, the airflow openings are first airflow openings, and the apparatus further comprises a third strip that intersects the first strip and the second strip while also spanning the ventilation openings so that the first strip, the second strip, and the third strip cooperate to define at least second airflow openings within the ventilation openings. The second airflow openings are sized to attenuate second EMI of a second frequency generated by the computing device.

In at least some embodiments with a third strip, the apparatus also comprises a fourth strip that intersects the first strip, the second strip, and the third strip while also spanning the ventilation openings so that the first strip, the second strip, the third strip, and the fourth strip cooperate to define at least third airflow openings within the ventilation openings. The third airflow openings being sized to attenuate third EMI of a third frequency generated by the computing device.

In another form, a computing device with enhanced cooling is provided, the computing device comprising: one or more computing components that generate heat and electromagnetic interference (EMI) during operations of the computing device; a ventilation area in fluid communication with the one or more computing components; and an EMI containment component formed from two or more intersecting strips that spans the ventilation area and defines airflow openings within the ventilation area, the airflow openings being sized to attenuate the EMI.
