Perhaps taking a pair of scissors and 'rounding' the leaftips...? <kidding>

The benefits from fresh air and the CO2 it contains, far outweighs the leaftip irritation the fan's cause on other leaves. Rotate the plants so the same leaves don't get the same irritation all day every day, or gently tuck the offender down to prevent the assault. But it's normal, and nothing to get tweaked about.
