Radeon HD 6870 vs. 6950. Is there a big performance difference?

    I personally feel that case will struggle to keep the temperatures down on even one HD6950, and thats with both fans being used (front and back).

    I urge you to consider purchasing a reference design HD6950 if you have to continue using that case.

    Another option would be to drop the 1100T in favour of a 1055T/1075T and use the surplus money to purchase a case with better cooling. In the grand scheme of things it might be a better option.

    I was thinking about getting the Eurocase ML 9801 X2 COOLING case. Would that be good enough?

    That would offer loads more cooling for your setup, and therefore I would advise it over the original case you mentioned.

    It costs above 70 euros with VAT. Would CoolerMaster Dominator CM 690 Lite II Black be better than the eurocase? It costs moreorless the same.

    The CM690 would be the best solution of the lot in my experience. It has capacity for 10 fans, which will provide more than enough cooling for the entire setup in the hottest of conditions.

    You will need to order a few fans though, but I would recommend you recieve it first, and then go from there. But a fan or two at the front is recommended to cool your hard disks, and I would definitely go with both side fans exhausting air to get rid of the heat of the GPU(s). Using the top fan on exhaust is recommended too, as hot air rises so its a natural way of removing air.

    This gives a cheap example of airflow using the extra fans:

    Also bear in mind the two side fans will be blowing air out of the case as well. With so much exhaust fans it kind of causes a windtunnel effect inside the case, and does a fairly good job of removing hot air.

    I don't really want to order extra fans. I just would like to have them already in there, no extra buying.

    BTW Would this amount of space be big enough to fit the 6950?

    I believe its a shade under 300mm in length, so you should be fine with that case.

    Yeah it is 27 cm long. So it should be big enough.

    What about the NZXT Lexa S or NZXT Hades as a case? Would that be better than the CM690 or the Eurocase ML 9801 X2 COOLING? Would the CoolerMaster Hyper 212 + fit the NZXT LEXA S or NZXT Hades?

    I would like a case that already has coolers in it. Should I just use my current case and buy coolers to put into it?
