Yeah, fans aren't going to do a thing. For example, I have a 6" 435cfm inline fan specifically for venting my 1000w cooltube setup and and a portable fan for circulation and I'm still running about 90 degrees in my closet. My apt a/c is set to 79f and runs non stop. I live in the desert though so temps outside are consistently 100+ degrees... I'm about to put a portable ac unit in there and add another exhaust for odor control..... I can't wait for winter lol.
