    Your current board will allow it. The PCI-E spacing is sufficient since your have two slots in between your PCI-E x8 slots.

    @ Erocker: Look @ what this guy said... I'm pretty sure the space would be just about insufficient because yes I would be able to fit both cards with the accellero xtreme plus ii on, but I'm barely have a centimeter seperating both cards meaning I'd get a lot of heat on the top card... wouldn't I ?????

    I will be like 5*C hotter on the top card than the bottom card at the extreme end of gaming loaded temperatures.

    The way the fans shroud is designed, it can pull air even if there is a flat surface they sit on.

    Yeah, he's kinda wrong**. My motherboard has the same spacing and I use two Accellero Xtremes on my 6950's. Heat won't be an issue and for a tip.. if you have a side panel fan, use it as an exhaust.

    Since at the moment there is no response to whether one card will get too hot due to possible lack of space, there is a cooler which will resolve the space issue.

    I would say it will most definitely be more expensive than the AC VGA cooler but I do not know for how much.

    See if the Thermalright Spitfire is compatible with your cards.
    Have one of these on the top and the AC EXtreme II on the bottom.

    It won't. I get about a 2c difference in a case that is much more cramped than his.

    *Just realized I do have an extra slot between my cards however, there will be enough room. The fans don't draw air from directly above them anyways

    Yes thats right. you caught my bluff Mr. Erocker.

    Despite having the issue with space on my previous mobo a Asus P5Q Pro & also the same problem when i fitted my 5850s into my P8z68 V Pro

    and if you look clearly at the P5Q Pro, the PCI-Ex gap/spacing is almost identical to his i55


    but you know what, Im wrong.

    aparently my personal experience means very little on these forums.

    In an act to up my post count, I had to resort to lying about my personal experiences with this topic at hand

    Good day to you sir

    Actually I found out you're right, read the post above yours.:eek: I did have these cards on my gigabyte board and it actually does have the same spacing as your board. I did not have a heat issue at all and I have no idea why you did. Perhaps having your side fan as an intake?

    Perhaps you shouldn't take it so personally. I thought the spacing was the same and if you want to be upset about it I'm not concerned. The cards will still fit. Good day sir.

    and maybe you should do some re-search before calling people wrong.

    I was wrong on the spacing of the PCI-E slots however I'm not wrong that the cards will still fit on his board with those coolers on it. Like I said, I have no idea why you had the heat issues since I have run my cards in the same slot configuration on my Gigabyte board. So, yeah I made an error on the slot configs. but I'm not wrong.

    well guys.... This thread is about helping me about installing new VGA coolers on my cards. I'm really thankful for all your input, but there's no need to start fighting about who's right and who's wrong because in the end, I'm the one who's gonna have to do a decision...

    Now, my question to ERocker is: "Where does the hot air get exhausted if the Acccellero xtreme plus ii sucks air in with it's 3 fans" ??? Now that might sound like a noob question, but I'd rather make sure than make some wrong assumption...

    the fans blow the air onto the PCB and then it flows outward into the case, hence why erocker advised a side door exhaust fan;)

    The fans blow down on the card so it exhausts out of the sides. This is why I recommend using a side fan for exhaust. If you don't have a side fan, it's fine, just don't use a side fan as an intake as it will mess with the airflow.

    yeah, I just modded my phantom case so that I have a side window... so no more side fan config possib for the moment (except for the 2 small 120mm fans further down the side panel...)

    How should I set my 2 top 200mm fans (the ones on top of the case)

    Because my current fan config goes like this:

    1x140mm fan at the front sucking air in
    2x120mm on the left side panel sucking in
    2x120mm fan in a push pull config blowing the hot air through and out of the radiator (coolit alc eco)
    2x200mm fan on top (one as exhaust and the other as intake...)

    2x120mm fan in a push pull config blowing the hot air through and out of the radiator (coolit alc eco) good
    2x200mm fan on top (one as exhaust and the other as intake...) Either or... I would try them as intakes first.

    Just to give you an idea how close these cards are when they have the coolers mounted



    the top card will get pretty hot as they are so damn close together, also read some of the top comments there. the owner admitted that the top card gets pretty hot as the bottom card blocks the fans.

    That is not enough spacing. I am using the Asus P8P67 mobo with similiar layout so I am guessing the tempt of the top card will be much hotter than the bottom.
