Slimbo-

Half an inch is plenty. The truth is that our Victors only rarely get hot enough to warrant the use of the fan. By the end of the match, I suspect that Victors running drive motors with out fans would be a little toasty, but probably not near failure. This is a bit like the case of putting heatsinks on motors- it helps in the long term, but over a two minute match, it's not really effective. Cooling the Victors shouldn't be a huge factor for us, as long as the fans are running, the Victors will be more then adequately cooled (which is why they are there- so you don't have to ever worry about them overheating do to poor airflow).

Bigger considerations in my mind with a tight clearance like that is going to be accessibility and visibility.
