Ventilation Help

So I thought because I didn't have any intake with the little exhaust I had going, that it wasn't circulating enough, which was making it hot. But I recently bought a new tub and rigged up 2 80mm cpu fans, one for intake and one for exhaust, both fit into each side of the tub. I have them both facing the same way so one is blowing in and the other out. The exhaust fan is connected to a 12V adapter and the intake 9V. Should this be the other way for better circulation? I knew one is better to have more power. Also is there a different fan I should have gotten to take air out opposed to just facing the fan outwards? But now that I think of it, I never have the top on so would it even matter...? I thought the heat may have been because of the closet, but even when I let it out into my room the temp. doesn't seem to change much. Maybe the thermometer I have isn't too accurate, would a digital thermometer be more accurate? Because it really doesn't feel as hot as it says it is (80-90 F). I also have another fan inside connected to a 12V but is quite bigger, so there's quite a bit of circulation. I don't know what's the deal with the temps in this thing. I'll post some pics, someone please help me out here! Thanks

Turn them both facing out and cut a larger intake hole.

Thanks a lot for the input, care to explain a lil' more in detail please? Like how does facing them both outward benefit more than one coming in and one going out; how does that work? And an intake hole? Like just a seperate hole with nothing in it somewhere on the side?

Put a fan at about where your ac outlet strip is and blow in toward the intake fan and see what happens.

Like the other post mentioned, by having one fan blowing in and one fan blowing out you are limiting airflow to what the fan blowing in is capable of. You could put both fans blowing out on the same side if you want and leave the intake hole open and they should get all the air they from it with limitations. Or put each fan on the ends blowing out and put a new intake hole somewhere in the center.

Then if you still have problems you can move up to bigger fans.

Word, appreciate it. Did y'all see the part where the top is NEVER on. Is something weird here? Ha. I just would think that with the top always off, it wouldn't be necessary to have intake holes and such. So I should make a hole on one of the longer sides, towards the top or bottom?

Turn the tub 90 degrees and blow air in from outside the closet, you need fresh air. You can circulate all you want inside but you must introduce fresh cool air from outside the closet. Turn the tote 90 degrees, take the big fan you have inside and place it outside the closet pointed toward your 9v input fan (about 3 feet. Give it a try

Nope missed the part about the top never being on. If you are having heat problems then you need intake and exhaust on your closet, putting them in the tub won't make any difference because you are blowing around the same air that is in your closet, You need to pull some fresh air in, usually at the bottom if you can and blow out the exhaust, at the top of your closet if you can. Then you can only get the temp. as low as the air you are pulling in.

Did I get it right that time or do I need to read your description again ?

Yeah you got it right. Thanks a lot. But I also mentioned that I've even tried taking the whole tub out and letting it sit in my room and that's not seeming to help. Wtf. Really. I don't get it.

Well when you say not much at least there was an improvement. By the sounds of it you have no neg pressure into the area so lets get crazy and put something OVER the tote to create a controlled environment. Worth a try. Good luck
