I was referring to a particular kind of product. > - As others have noted, significant fan noise is generated not from > the fan itself, but the sounding-board properties of the > motherboard and attached components.

The reason for the proximity of the fan to the heatsink and cpu is for an immediate cooling of the heat critical and sensitive cpu. In the particular heatsink fan combination I am speaking of, the noise is low, efficiency good, and removal of feet^3 per second is considerably better than the standard heat sink fan combo. It is a trade off, but I wonder how much noise (in normally operating cpu fan) can be attributed to the soundboard properties of the motherboard/components/sheet steel back. Just generally it seems far more likely that objectionable sounds will arise from the power supply fan. I just this second found the name of the Co. that made the cpu heat sink fan combo and power supply fan I am using. It is: PC POWER & COOLING INC.
