 In checking out the fan on the IBM8580 that will be in a small-engine repair
shop, I found that the fan is located in the bottom center of the power supply
cage and it blows air over the internal components in the body of the 80
casing. There is an intake vent in the rear of the power supply. In pulling air
in thru the PSU cage it must also be cooling the PSU components as well.

 I'm wondering what problems I might encounter if I put some sort of a light
filter e.g. range-hood filter cut to size over the intake vent ? Would the
increased load on the fan overload it ? If the restricted air intake caused
the fan to pull extra air thru the side-mesh of the PSU cage from the inside of
the casing, which it must do now to a limited extent, would that be enough to
suck air thru the floppy opening and defeat my purpose ? Any ideas ?

Lawrence
