Hi, how big is your box mate?
I use a small cupboard and I have found that a mix of large exhaust and smaller intakes works very well and keeps temperatures stable. I have used Led and cfl lighting

(L)400mm (W)200mm (H) 450mm... that's what I am working with. I did a test run there during the week with 3x 35w cfl's and just 1 intake and i was getting 27.7°C without the fan and it dropped to about 23.9°C after running it for half an hour. So I am thinking on just having the two outtakes and the 1 intake. What do you think? ***The 3x 35w's are for VEG, I will be running 16x 20w's for FLOWER*** Haha i know that's allot for the room i have but i have a light fixture made to save space, ill post it when its done :booya:
 
Wow that is small. I have found that 4x 70mm (I think) and 3x 120mm exhausts keeps my box at about 25oc. It took a bit of playing around and I have tried a few different fan sizes but this works well for me.

It's probably best to have a go and make some minor adjustments. I can show you what I have if it helps

If you could put the fans in the top of your box I'm sure they would be more effective I have a few restrictions using that cupboard so I just put the exhausts as high as possible.
 
that looks great man! yeah, at the top of my box would work well, but because of my light fixture it wont be possible. I am really restricted by dimensions, witch is unfortunate. Again your grow box look FANTASTIC, just had a look at your Cupboard lowryder grow :smokebuds:
