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.
