Hello Greg - 

GE>>> workstations. Very short desktop cases, so the fans slide
GE>>> into the full-length PS area diagonally. Standard 80mm
GE>>> outside, only 15mm (19/32") thick. 

CA>> What you describe sounds about right. I didn't measure the
CA>> fan when I had the ps removed. I suspect you mean the fan
CA>> is installed horizontally and not vertically? ;-) 

GE> Nope. Definitely diagonal, as the case is only 3" high. 

Very strange but I believe you if you say so. :-) 

--8<--cut 

CA>> I decided to do as Matt has since suggested 

GE> Okay, then. You had your chance. :) 

GE> I'm going to build some brackets and funnels, and use them
GE> to replace the mini-tornado CPU cooling fans inside my
GE> boxes. Big+slow = quiet. Small+fast = LOUD. 

A squirrel cage blower would be more suited to ducting air to
various parts of the machine, if you could find a small one.
Modify a hair dryer? ;-) 

CA>> and use a muffin fan I have here with a power cord
CA>> soldered onto it.

GE> Yes, in-stock "standard-size" parts are rather convenient. 

CA>> I placed this external fan at the back of the vent for the
CA>> ps just to see if this was the _only_ reason the machine
CA>> was failing to remain running. 

GE> That's also the way I've seen mentioned to quiet down the
GE> fan, as there's a lot of turbulence (noise) induced when
GE> the air is compressed against the inside of the flat metal
GE> "safety" grill by the fan blades. You can also cut out the
GE> entire PS grill area to boost the flow, and find an old
GE> XT-era thin-wire grill, or make one out of that "hardware
GE> cloth" stuff (1/4" square mesh) to keep little fingers out
GE> of the external fan. 

I did that originally (had two of these extra muffin fans)
because my children were little and curious. The tight 'mess'
of the wire grills really cuts back on the airflow a great deal
more than you would think when the mess is 'tight'.
