Hah!  :-)   One sensor (the "ambient") was suspended above my workbench, the
others were affixed by DOW Heat Sink Compound to various locations inside the
system, on the motherboard, etc.  The system felt cool to the touch, contrasted
to a "standard" system which feels hot (to me).  I don't believe I've violated
any Laws of Thermodynamics although, come to think of it, the air-suspended
sensor "could" have been warmed by the high-intensity incandescent lamps I use;
not quite a patentable situation!  :-)

Actually, this may be of interest: the new location of the fan is one of being
suspended above the motherboard INSIDE the system (not along any case walls)
both blowing and sucking air across the boards (two tiers).  The air intake
along the front of the tower case is filtered using some plastic filter pads I
picked up at (the local) Weird Stuff Warehouse.  The fan is fastened with
silicone washers and nylon hardware to an "L" bracket secured to the case's
pan and in front of the power supply (245W).
