I've played with this a little...
The first one I did was a water-cooled, dual-peltier "sandwich" cooler. I
use a refrigerator compressor to chill the coolant to ~5C and get the cpu
slug down to around -40C. I can run my Celeron 366 at a stable 710mhz with
that one.
The second one I did (well, implemented anyway) is cooled with compressed
gas. The coil is fed with a 2000psi dry-air tank and is attached directly
to my hot plate. I also get the slug down to between -50C and -40C with
this one. I've had the 366 running above 800mhz with it, but the tank runs
out before I can do any hard-core tests for stability. The nice thing is
that the vented gas can be blown into the case or across heatsink fins to
further cool the ambient temperature. Someday I'll invest in a larger tank
(arc welder type or something) and see what I can do with it...
You might want to explore cooling with a Hilsch tube, but I doubt that
you would achieve temperatures that low. (Gawd! I haven't thought of
one of those things in eons!)

anti-freeze with a circulation pump? Is anti-freeze conductive? I'd like
to try that!
Some years back they sold cooling fans that
included a
peltier-element (a diode running a DC current that cools on one side and
heats up on the other). The exess heat needs to be fanned away. This way
you should be able to effectively overclock a 486DX100 in a practical
manner.
