Will this setup be ok?

Hey guys, I am currently growing in my closet with 6 27w(100w Equivalent) 6500k cfls. Im thinking about upgrading, so i already bought a 150w hps for 80$. Im thinking about getting a GrowLab GL60 which is 2feet x 2feet x 5feet 3inches tall. but im worried about the heat, so i was wondering if 2 "Can RS 4 HO, 178 cfm", one for intake and one for exhaust. Will that keep the temps cool in my grow tent? ill leave all the links to what i want below so you could check it out..thanks for any input. Also, Im not getting any of this online, my local hydro store has it all and the links are just to show you what they are...thanks again
I also live in a warm part of the U.S. so temps are usually about 80 in the summer and around 70 in the winter.

It should he fine the key to growing is preperation the rest is pretty natural keep us posted on how they are doing.

you'll need to cool the ambient temperature in the room where the tent will be during the summer with an air conditioner...80F in the room means 90F in the tent at least...so try to keep the room's ambient temp lower than 75F if you can

Surely he only needs one of those fans for exhaust? not intake?
