yes it think so, 95 is way too hot cuz the ideal temp for photosynthisis is around 78 F so the hotter it is the less yield you will have. Or look at it this way the hotter it is the more light you are wasting cuz the plants wont be able to use it as much so its a big waste.
I had the same problem I finally solved it buy cutting a hole in the ceiling and putting a strong exhast fan in there. it worked real good
