Well heat be a issue?

I plan on getting a 240cm width x 120cm length x 200cm height grow tent and run 2 600w hps in it with just a exhaust fan 4" , will I be ok? I'm located in Europe, regards.

My 400w closet is a bit warm even with a 4" blower exhaust fan and an oscillating fan blowing straight under the bulb if i was to have
it on during the day temps.

Would a 5" extractor fan kit reduce even more heat? Baring in mind I don't want an intake fan just exhaust...

I have same tent and same lights. I doubt you have enough air through it. I have a 6" exhaust and it sucked the sides in way too much so i slowed it down, then it was too hot - I've added a 6 " inlet fan with less power (330 as opposed to 550) and now it holds at about 80 degrees. The inlet fan runs at full power when light are on, and the exhaust at about 3/4 power so i have a bit of neg pressure. Depending on the room temp I think if i were you Id switch the 4" to inlet and buy a 6" for exhaust or it'll be too hot...just my experience - unless you have cooled hoods...
