This is not the situation to which I was referring.
This is why I said "local separation of (into) hot and cold" (within the
pc). I was referring to a particular kind of product.

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.
Hope they are still around and on the web.
