Will 2 - 4" inline fans cool 1 600w hps in 2 x 4 x 5' tent

I am just curious if these 2 - 190cfm 4" inline fans will cool a 600w hps if it is in a sealed cool tube reflector with air coming from outside the tent passing by the bulb and exhausting on the opposite side. One of the 4" inline fans is exhausting through a 4" carbon filter. So in total I have nearly 400cfm in a 2x4x5 space with a air cooled light. I have been kinda worried that I should have went with the 6" inline fans but I was gifted these 2 4" fans and I thought they would work and still do think they will but I would like to be sure. Also if I am exhausting my 600w out of the tent into my room will my room end up getting really hot or with my central A/C keep the room tempertures in the high 70's at least. My house usually stays around 72 during the summer, my room is 15'x12'x8' and my bathroom is 10'x5'x8' so pretty much I'm asking will a 600w overheat a area this large that is cooled by a central A/C unit. Will I even need to run both fans at full power or not?

Too many variables at play. Buy from a retailer who accepts returns and try them out.

I'm still curious to see if anyone has a similar setup to me and if they are successful with this ventilation setup for a 600w hps. I can not exhaust to attic without cutting hole in attic floor and cannot exhaust under house without cutting hole so the only place I have to exhaust the heat is in my room. Would it help if I put a window A/C unit like 5000btu just to help keep temps cooler. I am growing in a hydroponic setup so I know temperature is very important, I don't want to get pythium or anything like that I would just like some more input from others. Thanks deadgro for your input I appreciate your response.

Just spend the money on a cage fan rated at twice what you need and install a dimmer. It makes controlling temp a lot easier, it comes in real handy if you have to deal with dramatic season changes. and if you ever decided to upgrade at least you'll alreasy have the fan power. Just "personal" experience.

Just keep in mind the fan cfm should be lower than the filter cfm in order to deoderize properly.

The fan came with the filter, I think the fan cfm is slightly lower than the cfm rating for the carbon filter.

I think I have plenty of fan power I just don't know if exhausting in my room will make my room uncomfortably hot if I have central A/C that is my main question.

It will, I have both tents in a room, the flower tent goes into the attic and outside, but my smaller veg and mom tent with cfls just blows into the room and even that get its pretty warm to where I close the floor vents once the flower tent turns on

Bad news its not cooling my space I have to run the light at 50% or it will exceed 90+ degrees in the grow space, I don't know what to do.
