I hope this has not been asked before.  On the December issue of Byte (p.132),
there is a short article on an interesting cooling device, which can be
mounted on a CPU and is able to cool the chip down to 0 degree centigrade.
This device, according to Byte, is a Peltier effect device, which is
"a thermoelectric cooling system based on the principle that passing a current
between two physically connected, dissimilar materials produces cooling on one
side and heat on the other."  I am not quite sure if I know what this
sentense is talking about.  Can someone knowledgeable elaborate this a little
bit?

BTW, in case you are interested, this device is used to push the 486 to 50Mhz.
I am not sure what the 486 is originally rated?  (33Mhz?)
