Indeed. Extra heat shortens the life of electronics in many ways. But extra current plus extra heat gives a double whammy to the metal traces. The result is greatly increased electromigration. That is a phenomenon where the metal conductor slowly flows like a liquid under the pressure of the electrons coursing thru it. It flows fastest where the metal necks down or turns. That forms voids at those discontinuities. And voids are hard failures. (He's dead Jim.) Electromigration is highly non-linear. So a small increase in current + temperature can reduce the life of your chip(s) from 20 years to <1 year. I have had four computers. I kept them for about 15 years (CP/M), 10 years (Amiga), 5 years (Linux+Dell), 1 year (Linux+Abit but flakey). I intend to keep the current one (Linux+Gigabyte) for at least 5 years. I don't need to be shortening its life. -- Allen Brown work: Agilent Technologies non-work: http://www.peak.org/~abrown/ [EMAIL PROTECTED] [EMAIL PROTECTED] Heck is where people go who don't believe in gosh. _______________________________________________ EUGLUG mailing list [email protected] http://www.euglug.org/mailman/listinfo/euglug
