I have tried searching, but either the space is smaller than mine, or they talk about air cooled hoods exclusively.
you are fine with the temps, just don't go below 65 the lowest at night. You aren't even going over 85 right now.
If you put that hid in there, it WILL get hot, and a cooled hood would be the best...especially if it's a sealed grow area. Ballasts get hot, but nowhere close to the bulb. If it's remote then no worries on adding that extra heat in there.

You might have to test it out, it's hard to say how efficient your room is at cooling down with those fans. I would like to guess that with a vented hood and that 9'' fan in there you could keep it within range.
