I run a 5inch sized 24V fan powered from 12 volts or so during RTTY contests. I watch the PA temperature, but don't normally see it going above the upper 40's no matter how hard I push it at the 100 watt level.
The added fan blows in through the top vents as the normal fans pull air out. With rubber feet on the fan, and a screen to keep wires and fingers out, it works really well for me.
