I have a hard time believing you'd be overheating the ballasts to the point of failure just because they are in a stand. If they have plently of room all around it shouldnt be that much of an issue, if they needed a fan they would be built with one (as some are). On the other hand obviously the cooler the better and adding a fan would be a good idea regardless. Sounds to me the issue lies elsewhere. You may be overheating the ballast but I dont believe the reason is from sitting in a stand.
