Out of interest, has any of you tried a riserless board with non-blower-style GPUs? Surely they're too close to eachother to work efficiently, i.e. heat cross-contamination must be terrible?...
I will be doing just that - and yes, they are awfully close together. I'm planning on using supplemental fans to blow air either down onto the cards or across from the side opposite where the video jacks are.
I plan on doing the same with the octominer motherboard, but I'm not sure when I'm going to get it. I have 8 GPUs on the way, does anybody know where to buy the Onda?
