Does anyone have general guidelines for how to position two different versions of cards in SLI for optimal cooling, especially if they have different clock speeds?
I am currently running the Asus DirectCU OC 4GB version of the GTX 770.
Unfortunately, it seems to now be sold out everywhere, so I've ordered a Gigabyte Windforce 3X as a second card.
My motherboard is an Asus P8Z77-V PRO (http://www.newegg.com/Product/Product.aspx?Item=N82E16813131819).
The current card (Asus) has two fans, an impressive heatsink, and a backplate that also seems to dissipate a good amount of heat. The Gigabyte has three fans; not sure if it has a backplate, but it comes clocked a bit higher than the Asus. I don't think either of them has a "pure" rear exhaust like some cards do, i.e. they will both probably blow hot air in all directions.
I'm going to be using them partly for gaming and partly for rendering in Octane.
I think I would expect the Asus to run slightly cooler than the Gigabyte under load, but the Gigabyte will probably move more air. Does anyone have any advice on which one should be the "upper" card and which should be the "lower" one?
