Well, several people have responded so far and asked questions about the
themoelectric coolers for 486's, so I'm putting a little more details here.

  486 "Chip Cooler" = Heat Sink + Mini-fan + Thermoelectric Cooling Module

The "TCM" is a Peltier junction which acts as a "mini-refridgerator".

The unit is 49*45*23 mm in size, and mounts onto the CPU with a plastic
frame that holds the unit snug against the CPU.  Included in the package
is thermal compound that eliminates the air-gap between the cooler and
the CPU. (Side note: if you ever buy heatsinks and/or fans, _make_ _sure_
you get the compound and _use_ _it_!)

The unit comes with a standard power attachment connector so that you can
plug it into your spare power cable.  The mini DC fan attached to it is
quiet enough that you'll probably not hear it in comparison to your main
power-supply fan, or your hard drive.

According to the specification that I have, it will keep the CPU's surface
at 25 degrees C (assuming a 5-watt heat generation) with the ambient air
temperature also at 25 degrees C.  (This is in contrast to a straight
heatsink which puts the CPU at 71 degrees C, and the heatsink+fan at
48 degrees C.)  Because it's at 25 degrees C, there would not be
condensation (as some concerned netters pointed out).

I plan to sell the unit at $38.00 each;  to make this feasible, I need at
least 24 buyers.  

Also, special Pentium-coolers with "programmable cooling power" exists, too.
I don't have much details on them, except that they _do_ exist and are
available (if enough people ask, I'll find the pricing on those, too).
