I just had this conversation with someone last night.
The only time we have ever had a problem with anything overheating was when we played our finals matches on Einstein last year. (For those of you who don't know, the Einstein division field was outside last year.)
Heat + humidity + running a lot of matches = overheating.
To solve that problem, we sprayed cold spray on our electronics after every match. I don't think anyone will have to worry about overheating because of weather this year (all of the fields are indoors!)
Other than that, we've never had a problem with overheating, even during other finals matches. The weather was the only thing that affected us last year ::shrug:: You should be fine.
