It's funny how i've never had a problem with overheating of my units that I build, even though I live in a sub-tropical location. It gets up to 40ºC + in this room some days, and the computers never seem to get over 40ºC all that much. The cases I choose have good ventilation and I try to improve on my installations so that the air flow isn't compromised in any way. The Antec P160 case I am using for "Panorama" is a bloody excellent design and it's hard to choose another one that will be better. The Antec 900 that I put together for Gee was a great case as well with a 180mm fan right in the top of the case, and the PSU down at the bottom rear of the case.. It was only a mid-tower compared to the P160 though.

My troubles only started when I used a stove as a graphics card Kev. This new case should cure it, it will blast between the hard drives and right across the top of the stove. KC

The way things are going, the heat problem is going to get worse unless the graphics card manufacturers change their tack, and find a chipset that doesn't get hot ! Liquid silicone graphics maybe, what's happening in that field ?

My card has got 2 x 70w power connectors, the 4870 x 2 has got 4 connectors. You cant keep adding power, without producing heat Kev. If they keep going this way, the graphics will have to be a seperate unit and have its own PSU. At least I have got a choice of PCI-E slots, a lot of people have only got 1. If I used the top slot it roasts the CPU and I have to use the bottom one. Then I need a storm force 12 to stop it cooking the mobo. The graphics companies seem to have lost the plot somewhere along the line. They are so busy trying to out do one another, they are not thinking straight. They are either going to cut the power down or go to liquid cooling. There is a liquid cooled 4870 x 2, but you will need a second morgage to buy one.

That's quite a case you've got there. My Coolermaster 932HAF case is just a frame supporting open grates with very large fans on 5 sides. If that doesnt work for you then I would suggest something similar.

I was looking at one with a 10 inch fan on the side Dave. I decided against it as its blowing the heat onto the mobo and I thought air blowing across would be more effective. The big fan was putting a lot of air in, but not much helping it out. This one is blasting in the front and sucking out the back and top. I think the system produces a much faster airflow, which is what I need and not internal pressure.

I always tell people that a good case is one that has a good airflow design. The way to choose that, is to remember that hot air rises. A case with a good sized inlet fan at the lower front sucking ain in over the hard drives, and another exhaust fan of approximately the same size at the upper rear is next to ideal. If there is one that exits at the top of the case, that is better still as in the case of the Antec 900 like Gee has.
These huge fans in the side of the case are useless unless the same amount of air they blow in, can get back out, and in most cases, that doesn't happen.

Pressure will create heat of own Kev, people don't seem to realize that. This new case is working quite well, although I don't know how they get away with calling them ATX. I have worked on pocket watches with more room to put things together. If the motherboard mounting plate didn't come out, it would have been almost impossible to build. I left the memory fans out, but I might put them back in later from the front. The motherboard wouldn't go in from the back with them on. Building computers had become too easy, now only clock makers can figure out how to do it. I think it was a good move to change the case though.

I have given up on using cheap PC cases now. The range of $40.00 cases are not really the best, so i'm going to use quality in future instead of price. CoolerMaster and ASUS Vento are some choices I have at around $85.00. These have screwless retainers and most have quality PSU's, as well as good extractor fans up to 120mm.
If I have a customer who has cost in mind, only then will I go for the cheaper cases. Cooling is important, and you only get good circulation in the better cases.

Not being a builder myself this may be a load of rubbish but, if possible I would be inclined to go for an intake fan in the bottom of the case which would be mounted on taller feet. I would then aim to create an even airflow by having exhaust fans mounted in the sides and top of the case.
The various internal components would cause an air turbulence within the case thus cooling the critical components.

The only problem there rog is dust. anything that far down in the case is going to end up with more dust than you can poke a stick at. Have you ever seen inside a case that hasn't been opened for a couple of years. All the dust settles to the bottom of the case. So what is the fan going to do? blow that dust up into the components!
