help me pick a blower*pics*

i have the chance to buy this blower but i dont know if its what i need. my room is hot so i need something to bring in cool air from outside, will this work?? i am planning on having this suck in cold air to blow into my closet, i dont know if it will work with a exchaust duct or if it is too powerful or if it warms the air, please help

if u can use a air conditioner to pump in air if u are using any hid. if not the air being blew into the room should be 65-70 degrees. dont let the room get over 80 for long or u will have problems

cant tell too much from the picture, i also dont know much about your grow room/setup, or how much noise you can make without getting busted. it looks like it can be hooked up to an air duct but thats about all i can really say.

over 2000 cfm, i dont mind the noise, its a 12" duct

just making sure it wont turn the air hot
