<DIV><FONT face=Arial size=2>A good reason to look for motherboards with either
Tantalum capacitors or Organic capacitors. Its a marketing point I'm
seeing these days, and as a design engineer, I can say its worth looking
for. The ESR in typical aluminum electrolytics is considerably
higher. These caps are at the output of a switching regulator on the CPU
that is handling many amps. This creates large charging and discharging
currents at hundreds of KHz rate. Any ESR (internal series resistance)
turns some of this into heat.</FONT></DIV>
