What would you do

Our AC broke and it's pretty hot/humid tonight. My sons (8 months) nursery is 81 degrees. I have him stripped to diaper, overhead fan and a box fan going to circulate air. We don't really have anywhere in our house that is cooler. Any other suggestions? Or do you think it'll be ok? He woke up once crying which is when I stripped him and gave him a few ounces cool water because he seemed pretty warm.
