Résumé

Thermal benefits of higher flow rates, that were realized by the blower fan at increased noise emissions, were determined. The acoustic performance of blower style fan-sink mounted on an advanced graphics port (AGP) card was also determined. The relation between fan speed and acoustic performance was determined by adjusting the RPM on the fan to operate at five different speeds by varying the input voltage. The sound power levels of the fan-sinks were calculated from sound pressure level measurements collected in a hemi-anechoic room. The result shows that increasing the fan speed, increases the thermal performance.
