Bill,

It is true that fan speed can matter in some coils.  It all depends
on the CFM of the fan, the "natural" quenching ability of the
coil, etc.  Some coils can use the full fan speed with no detriment.
It's not that too much air "over-quenches", rather too much air
can intermittently stop the gap from firing.
