Hi Ed,
        I don't use a fan.  I think there are so many pipe sections that the
gap stays cool enough.  Mine gets pleasantly warm to the touch.  You can, of
course, blow air across the gap if you want to.  It would greatly increase
the cooling.  It would also probably help quenching by blowing away ionized
gases.  I just never have gotten around to trying a fan myself.  It is
important to quench on the first notch.  The power dissipation is
dramatically less.  If one were really ambitious, you could flow cooling oil
between the sections insulated with plastic tubing.  This would be rather
complex to build but the power dissipation would be enormous.
