You may also want to try some coolers which use Peltier devices.  Only
drawback is they cost more ($40 to $70 each) and eat another 1.5 to 2.5
amps (at 12 volts) from your power supply.  Most of the devices say they
can keep the CPU below 60C (depends on CPU and cooling device
combination, of course).
