A fan module for use with fan trays or decks within a computer chassis for forced-air cooling with counter-rotating flow to provide higher static pressure. The fan module may have a conventional side-by-side form factor with a first and second fans supported within first and second housings. The first and second housings are spaced apart and arranged side-by-side. The first fan has a clockwise-rotating blade, and the second fan has a counterclockwise-rotating blade. In the fan module, the first and second fans may be axial fans with the blades rotating about first and second axes that are offset and parallel. In some embodiments, the fan module may have airflow through the first fan in a first direction along the first axis and airflow through the second fan in a second direction along the second axis, with the first and second directions generally matching.
