the problem with the HAF X is air filters. they don't exist:/

There are filters except for the rear fan placement.

I also own a 800D. Very nice and large case but i found the air cooling for that to be just ok. But as soon as i modded it with side intake fans it was very good
Here's another example of my 1st rig:

Put in some Sythe S-Flex-F fans on there and my temps for my 480's were alot better before the mod.

HAF-X or the HAF 932 w/ the fan door.

Tell you what; instead of posting a plethora of opinion substantiated by nothing other than forum banter, could you please link us to any instrumented testing that would verify your suppositions?

In other words, I'm seeking data to support the notion that with all available fan slots filled, the 800D is woefully inadequate for air cooling.

and i suppose you have empirical data to back up your claims as well?

physics doesn't stop working because you say so... if you pull air out of a closed container, there is a partial vacuum. any source that is removing the air out of that same container will be competing with each other as the pressure drops thereby reducing efficiency . if you can't understand this far, there really isn't much more to say... I might as well say the earth is flat...

Absolutely.

Looking back over this thread, here's your recommendation:

Now, the emperical data you desired (and this is with a STOCK 800D):
http://www.bjorn3d.com/read.php?cID=1791&pageID=8444


"As we put full load on both the CPU and the GPU we see that the Obsidian 800D has no problems keeping up with the Silverstone Fortress FT02. In fact, on the Fortress FT02 we have to speed up the big 180 mm fans to beat the Obsidian 800D in the case temperature. As we will see this comes at a cost."


"The Obsidian 800D has a nice low noise level even when we push all the components to the max. It of course also depends on the components but we noticed that even though the HD5870 was running at 100% activity the fan did not spin faster than around 30-40% which indicates that the Obsidian 800D is doing a good job helping to keep the GPU cooled."

Thanks for calling me out; your move, Psyclum. In case you forgot:

Thanks for the response thus far.
if you go for 6950 to unlock them, then try to get the "older" cards with dual bios! if you fail simple switch to the other bios and try again.

i also have the haf-x and yes there arent filters for the 200/230 fans but you can easily create simple pantie hose filters. i did the same, problem solved.
once a week you go over the fans (outside the case) with a vaccum cleaner and voila its clean!

Good responses so far. I don't mean to stir up any issues between competing brands. Its good to see some benchmarks to support what is being discussed.

Now these cases listed should be able to air cool reasonably well the components I listed (minus CPU) - ie: TriCF 6970?

Again, I hate to sound unsure, but the debate seems to be over the better case, and that would be my next question after knowing that 3x 6970s such as the MSI Lightning will work.

Thanks

well yes triple xfire will work.
also you could think about getting one 6990 (dual gpu + dual bios) which you can oc either
and one 6950 (unlocked to 6970) or one 6970. would be triple xfire with 2 cards = one card less that heats up to 60° or more means also less heat around the graphic cards

the haf-x also has the possibility to install an extra 80mm fan which can be mounted at the side of the cards and or install a 120mm at the end of the cards that is pushing the warm air from the front of the case through the cards to the back of the case

looks like this


the gpu holder on the left can carry a thin 80mm fan to blow directly between the cards

with the air duct you push the air to the back of the case

edit//
just check out the coolermaster site

better cooling possibility cause you only need 2 cards

you're welcome thx for pointing those pictures out which demonstrates just how effective the FT02 really is why or how you say?

NO air intake on the FT02 is UNFILTERED. whereas the ONLY place the 800D even have a filter is where the powersupply is. all other holes are unfiltered.


with a heavily negative pressured case like the 800D, you'd be packing dust in that case in no time flat. why does the FT02 NEED to go to high speed to cool down the case? because it's pulling CLEAN air through filters NOT just anywhere there is a hole behind the motherboard or above/below the motherboard or even through the 4x hotswap drive bays....

the BEST air cooled case is not just the amount of air you can push. THAT honor goes to the HAF line of cases since they use big fans w/o filters. the BEST air cooled case is one that you can use on a daily basis and not have to worry about how clogged up your GPU heatsink is or if the fans are still spinning at their rated speed because dust has gotten into the motor.

when it comes to computer cases, BEST means overall long term usability. not just 1 day of testing. I guess in YOUR world, dust doesn't exist.
