As electronic devices have gotten smaller and faster, the need for cooling systems has increased. Cooling systems may include multiple fans. For example, a computer may have a processor fan, a motherboard fan, a power supply fan, and/or a video card fan. Heat generating electrical components on the motherboard and in the power supply of the computer may heat up to varying degrees due to power dissipation caused by power loading. The various cooling fans may share a common air inlet, so fans for the motherboard and the power supply, for example, compete for air intake volumetric flow. The various cooling fans also create noise. Although the amount of noise produced has little impact on the performance of the fan or the system being cooled, noise can negatively affect people nearby.
