Suggestions to improve the airflow in my case?

Glad you took the time to draw these up and I have tried my hardest to figure out what the hell is going on but I have no idea what your configuration is to your setup....do you have a picture of your comp to go with these drawings?

Maybe just the setup itself is to foreign for me to understand...

EDIT: Is it similar to this?

Also found this:

Doesn't seem like there is much else you can do besides adding intake fans to the front and sides and exhaust it out the back utilizing as big as fans as the inlets and outlets will take.

Thanks for responding, guys. Yes, that is my case. I should been more specific in my post, please excuse.

Correction from the diagram actually, the fan in the PSU spins so that the air pushes in the CPU

I cut holes/added intake fans on the sides and also the top-left 60mm fan. The only outtakes I have are that top-left 60mm fan and the vents. I'm not able to fill the two 60mm fan spots behind the CPU because my heatsink is too large in diameter.
Should I maybe try to flip the PSU the other way so that the fan exhausts out of the top of the case?

Also, I labeled the view of the case at the top of each picture. So the direction of the arrows correspond to the direction.
Hope this helps.

Hmmm picture still looks to be the same I think...update link? In the meantime yes I would flip your PSU, you want that heat to exit your system and not dump it back into your case.

lol I didn't update yet. Too lazy, but I guess I will.

If you think of any thing else that may help, please post.

I'm going to rip apart my computer now.

OK, it's updated.

First off you want to have negative airflow for your case, keep that in mind. If you don't know what that is, it means to have more fans pushing air out then in. EX: 1 fan intake,2 exhaust. Don't forget since you have so many fans and varying sizes that it might be tricky.

all I can see is make that psu shoot hot air out the case

How do you know what he wants in regards to pressure? Positive and Negative pressure are covered in my guide. Decide for yourself which one you want based on advantages and disadvantages. Figuring out your pressure is easy to do which is also covered in my guide

Is there a such thing as a neutral pressure?

lol, I did the tp square thing and it just sits there basically(with maybe a hint of positive pressure...idk). Either way, how would I go about making it more positive?

Or should I try for negative? Do you have any knowledge of this case if it has enough air holes? I wouldn't know to compare to other mATX cases as this is the only one I've ever owned so far.

Thanks much,

Yes there is equal pressure which you can assume you would get a little bit of both worlds with. I prefer low maintenance myself so I go with positive to keep the dust out. Negative can net you some slightly better temps. Again it is really up to you.

For how small the Lan Box is I don't see it having an extreme amount of air flow in it and only being able to utilize the limited amount of fans and the size of the fans makes it that much more difficult. If your not having temp problems then I wouldn't worry about it. A good test to do is to take your load temps with the case open and then take them again with the case closed and see if you have a significant difference. If you do then it is very apparent that you do not have good enough case air flow. A little difference is fine but the problem will be if you see upwards of ~5c difference. Of course you will want to run these tests for a minimum of 30 minutes to see if your case is holding onto that hot air.
