bag of ice on the intercooler since placing a fan on it isn't really possible. If I had a car that rare and unique, I wouldn't want some clumsy person trying to hold a fan or find a way to put a fan on it. The bag of ice is less harmful... its just water. Just my $.02 since everyone else already answered the question.
