What computer case should I get to lower my temps?

Ok I already have a case for my computer. BUT it has holes on the side to show off the very pretty, but totally usless blue lcd lights inside. I have had some temp problems and I think that the fans I have in the front and back aren't getting rid of the hot air cuz those holes don't allow a vacuum effect (my own theory). I have heard of cases that are airtight and can keep a computer really cool (like a refrigerator). but I can't find anything. So I need some help. Anything I can do to cool this thing down?


Here is some Info:


I have a dual core amd 930 X2. 3G Ram. A evga 6800 GS PCI express vid card.


I really don't want water cooling!!!


Please help me out here guys. Thanks.What computer case should I get to lower my temps?
I used water cooling and thought nothing could beat it...until I bought one of those oversized heat sink fan/coolers. I was amazed. I am getting lower temps than I did with liquid cooling.What computer case should I get to lower my temps?
First make sure the inside of computer is free of dust, etc. Next make sure fans are clean, and all vents. Your fans may be in the wrong places to create the effect. I haven't heard of the airtight case and am not sure it would work. Go to pcworld.com and you may find lots of info to help you.
How do you know you have a temperature issue?





That setup should not have any issues with heat unless it is either completely clogged with dust, or overclocked a large amount.





The best type of case for cooling, in my opinion is pretty much anything aluminum.





Lian-Li cases are some of the best aluminum cases as far as construction and cooling is concerned.














You do not want a case to be airtight. That would not allow the heat from the components to be vented out and you would SURELY overheat.





What you want is a case that moves air in from the bottom of the case and out on the top, as heat rises. Ideally, you want to have an equal amount of intake and exhaust fans. You do not want to create a vacuum as that will cause issues with airflow.
Open your case and use a big fan to cool the system. It works for me in summer.





Or you can just get a bigger case. You might want to install some additional fan to cool the system.
There are so many cases now with 120mm intake fan up front and a STRONGER 120mm exhaust fan at the back. Pick the model w/ minimal obstruction to airflow. I prefer just a grill and not the tiny holes. There are good cases from Antec, Lian Li, Coolermaster, Thermaltake, etc. But there are cheaper ones (all steel).





Just for laughs, here's my favorite beast:
