Struggling With Temperature

i have just bought an hps 400 watt light, and im growing in a 5 foot by 3 foot rectangular grow tent which i made. there is a plastic and mylar sheeting on the inside and outside. the light gets pretty hot for that little room and i can only fear the worst. the temperature stays around 90-95f which i think is too hot. the humidity is a bit better. it is at 40-55%, sometimes 60%.
I have just turned a little fan heater into an extractor fan, and i have two vent hoses comming out of the tent that get hot air out the room in their own time. there is a fan oscilating in the room.
I was just thinking that if the thermometer says 95f, and there is a fan situated very close to the plants blowing reasonably strongly, and an extractor fan aswell, and the temp still reads 95f. would the plants still feel as though they were in this hot temperature, or would the fans cool them down despite the temperature still reading 95f?

No, at 95+ they will not grow very much, unless you supplement with CO2. But first, you need to exhaust more air, and that will help your high temps.

HTH

i am buying one of those tents for my closet, but im not going to use that cover, im going to buy a MH/HPS Conversion and get a glass enclosed Cover for it, with exhuast and have the fan sucking it out, and cool air from outside the tent comming in. thats how you do it, temps would stay norml, but im going to use c02, so i might need it at 90. Hmmm... it poses a challenge.
