controlling the temp in my cab. need help

[Dr. VanNostrin]

I have this cabinet that I bought and built and is in my closet. Dimensions are 19"deep 31"wide 53"high. Light is 250watt HPS. Temp inside without fans is around 110, yikes! I have a number of computer fans taking it down to about 90.5. I understand this is still too high, but there is not much more i can do cause i dont feel like taking shit apart and fuckin with it in mid grow. so i intend to take the proper steps in giving it proper temp next grow, which brings us to the question: I have 3 fans that are 80mm and around 25-30cfm and 3 that are 90mm and 60cfm. I also have a 120 mm one but i dont know the cfm. when setting up next time, should i have the stronger ones as exhaust or intake? should i do away with the weaker ones and replace them with some more 90mm 60cfm ones? i dont really want to put more holes in the cab either but if i have to i have to. should i use that insulation tubing to pull heat from the light? any other suggestions or advice? thanks for any help i really appreciate it

p.s. i know i posted this in the cabinet/closet section too but i really dont get a response very quickly or at all sometime on that board

Computer fans are made to cool a computer not a 250 watts. A bathroom fart fan pumps 80 cfm . Top Secret heat rises so put intake at the top of the space . With the vent at the top normal heat movement will help solve some of the problem. Use a attic controler to the fart fan. $13-20 bucks at a dyi. Temp controler is about 30 bucks.
Wooops forgot besure to use a intake filter on your system, no need to suck mites.
