I have problems with the temperature inside my growbox, i have 2 cfls and 2 fluorescent 15 watt tubes on 18/6 (my plants still on veg) and temperature have reached 100+ Farenheit . I know this is not healthy for my ladies. So far i have a 80mm computer fan that i use as exhaust and still the temperature dosent go down. I am guessing i need an intake fan as well but i need something small,quiet and that cools decently. Any suggestions?

My set up is:

My grox box dimensions are 3ft tall, 2 ft wide and 1 ft in lenght.

do you have an opening for fresh air to come in to the box. a passive intake should be enough. if not then you need a bigger exhaust fan and maybe a bigger passive intake.

well i have a like a small opening for air to come in around the middle of my box, its about 1 inch diameter. And for the exhaust fan its this one: http://www.amazon.com/Mechatronics-60x60x30mm-Fan-Model-UF60D12/dp/B000H27GJY/ref=sr_1_1?ie=UTF8&qid=1228578032&sr=8-1.

Im thinking of buying this one:http://www.amazon.com/Mechatronics-120mm-UF12A12-BTLR-inch-Cord/dp/B000F8W35M/ref=sr_1_1?ie=UTF8&s=electronics&qid=1228578195&sr=1-1 for fresh air to come in the box and put it in that 1 inch diameter opening in the middle of the box, ill take pictures.

Well here are the pics of the ladies and my fan. That big fan to the right of the box is not going to be a permanent fan for the box, i just put it in to attempt to cool the box down, but still the temps are 95 degrees Farenheit exactly. That small fan is this one: http://www.amazon.com/Mechatronics-60x60x30mm-Fan-Model-UF60D12/dp/B000H27GJY/ref=pd_rhf_p_t_2

I am planing to buy this bigger fan:http://www.amazon.com/Mechatronics-120mm-UF12A12-BTLR-inch-Cord/dp/B000F8W35M/ref=sr_1_1?ie=UTF8&s=electronics&qid=1228586096&sr=8-1 for air intake.

I will make the exhaust hole a little bigger and the intake hole the same size of the fan as soon as fan gets to me.
