We're not trying to remove all 1500 watts (is it even 1500 watts?) of heat.

You are. If you don't, heat will go up.
All that needs to be done is to achieve enough airflow to remove enough hot air to reach a temp range that is "OK"

Certainly I'm biased, but...

Trying to run more than a couple of ANY type of cards in an enclosed case  is trouble at best. 6990's being the double powered beasts that they are going to be even worse.

Taking the sides off and running large fans pointed inside is the only option really, but at that point are you really running an exclosed case anymore?
You'd be better off with an open frame rig.


The warmest card in my open frame rig is running at 78C, and the only reasons that card is that hot is because it's a 6970 and I don't feel like cranking the fans up to %80 or higher. to damn loud. They just run hot no matter what you do.

The 12  5870's in my rig are all in the mid 60's C. It's all air flow.

I have 15 cards running in a 32" x 20" by 20" space, and the only reason the card density can be that high is because the hot air is dumped outside and all the cards have enough spacing to get fresh/cool intake air.

That just wont happen in an enclosed case.

Sounds to me like the place you bought your rig from are just slapping the bitcoin name on a HAF X case without really doing any kind of research or testing to make a buck.

There's no question that an open case solution is best.  We're simply discussing options for a closed case.

Two delta 240cfm 120mm case fans will move enough air to cool down those cards in an enclosed case. They are super loud though, so that's the trade off.

Thats bs, you cant cool 3x 6990s in a conventional case.

This.
Everything else is rubbish.

Consider that the 6990's *alone* will generate about 1500 watts of heat output. That's on top of the heat coming off your power supply, processor, HDD, RAM, , motherboard, northbridge/southbridge etc.

Maybe a massive Silverstone Raven I/II case with tons of extra fans & upwards rotated motherboard tray can cool 3 of them (enough not to bluescreen all the time), but even then you'll run into heat issues. Not even the biggest Lian Li fulltower cases can adequately cool 3 6990's

Your options are pretty much running an open case or wind tunnel, or watercooling.

Think of it this way: Could any case out there sufficiently cool 6 separate 6970's overclocked? That's what 3 6990's are. It's mission impossible without improvisation, living in Antarctica, Finland or the North Pole, or removing side panels.

Christ you sound very sure of yourself but others seem to say otherwise. One guy has mentioned four box fans on the side case. I was thinking of mounting these after cutting holes with a hole saw in the side of the case. Then sufficient pull from the fans on the top should pull it out. The only thing I'm concerned about is blowing air onto the cards at too high a pressure as others seem to say this isn't a great idea.

We're not trying to remove all 1500 watts (is it even 1500 watts?) of heat. this isn't a race to 0.  All that needs to be done is to achieve enough airflow to remove enough hot air to reach a temp range that is "OK" it's also critical to improvise an outflow solution from the back of the cards.  I do this by removing hot air on the bottom of the case and out.  if your case has no fan on bottom front, you will have to improvise.  this is more critical than removing air from top.  lots of hot air in the back of the cards will raise the ambient temp inside the case.  it must be "re/moved"

- drill holes on the side panel and install 4 http://www.newegg.com/Product/Product.aspx?Item=N82E16835185060
I have these spaced out so that all cards are covered.

Next thing is to install plenty of fans to suck out the heat through the front of the case.  You probably have a spot for a fan towards the bottom front of the case.
I ended up putting 2 fans in series to expell hot air.

You also need to make sure you are able to remove all of the air that is being blown in, so do some quick math too.

my heat problem is solved, cases are closed.

Hi,
Thanks for your post. I think I'm am going to go the same direction. Can you post a photo to where you placed your fans? - I was looking at them and was thinking I would maybe need six but if you have managed with four that's great.

Thanks a mill.

I also said half a year ago (or so) that those setups are good only on pictures and maybe in refrigerated rooms.

Throwing side panel and pointing a box fan to the cards might do the trick too. But than again only in well ventilated room and only with very few of those boxes per room.

What a rip off. Their case with no cards is $1099?! My 4-card rigs cost $394 before cards and that's case/cpu/mb/ram/disk/fans/psu.

Hi,
I have a HAF X case with 3x6990's and adapter 0 & 1 rise exponentially to the point that the machine has to throttle and that's with them downclocked to 600Mhz already and the room is 18 celcius.

I asked this company how they keep their machines cool. http://www.bitcoinrigs.com/products/Professional-Rig-2000.html

They say the case provides adequate cooling for all cards and that the spacing is key. I have the spacing down.
I asked them about my case and that I couldn't keep it cool. They said they have the BIOS switched from default to keep them from overheating.

Is this possible - I thought switching the BIOS increased the watts?
