loonym, sorry to bother you again, but how did you put a fan on the nb? i've also have a TRUE in push pull, so on one side of the circu pipe is the heatsink fan, while on the other side is the back of vga card and can't imagine a way to push some fresh air on the nb. do you have any pics of your rig?
My SB is getting very hot theese days, (my room has 33° C) and reaches as high as 65° C while playing games in SLI. The strange thing is that the sb temp reading seems to be linked with the 2nd GPU as it goes up and down according to the GPU ambient reading with a margin of 2°C difference. Is there any way to active cool the sb? i've tried to put a small 40mm fan on it, but there are not enough space under the vga cooler.
i've also tought to replace the circupipe with HR05ifx, i've got two of them, one SLI version and one normal, bot neither one fit between the two 8800 ultras.

Fiskbit: Thanks for the words of support, we need all we can get with this board. I'll be running 8800GTS-512s like yourself, albeit BFG instead of EVGA. Can't really go wrong with either brand. I'm anticipating more issues when I do it so like yourself I am tackling them one at a time.

I agree with loonym that 3DMark06 doesn't always seem to scale well with SLI, or at least that's what I've seen in my research. Likewise, though, Crysis should show some noticeable gain. Most people point to drivers in cases like yours but I'm a bit more old school and would say check the hardware instead; I know, for example, that one solution over at the MSI Forums for SLI instability on this board was to use just 1 SLI connector.

I also have read that our cards tend to automatically slacken, even in SLI, if temps get a bit unwieldly. I'm not sure if this is true but I can tell you that my single 8800GTS hits 62C core load on this board and you generally want to stay below 80C. I use Rivatuner to boost the fan speed manually on startup. The GPU temps show up in Everest quite readily and obviously.

loonym: I'm glad I'm not alone, and I know all about cooling mods...I've just been a more relaxed OCer in recent times so I need to get my feet wet again. I will say without a doubt that a lot of the problems I see on MSI Forums with OCs and stability are no doubt linked to the two problems I had. I can say with certainty now after runnin OCCT overnight that indeed I overcame that second hurdle. Your perseverance in this thread and at the MSI Forums is much appreciated by the community.
