In order to cool high power modules using conventional forced air cooling, large air volume flows are required through the card columns to give the high air flow velocities required. This in turn leads to acoustical problems due to the large axial fans required to deliver the volume flow. This is very apparent in such noise-sensitive products as CRT displays whose function may well be limited by the necessity to use quiet axial fans in order to meet marketing requirements rather than by available technology.
