Trifire 7970 order in case

[cbrunny]

I've just picked up a third used 7970 for some trifire gaming in 1080p eyefinity. Wondering which order would be best to arrange them. The three:

XFX Double dissipation - two slot
PowerColor reference cooler - two slot
Asus Direct CU II - three slot.

I'm thinking Asus, XFX, PC from top to bottom. Thoughts?

Case is corsair air 540 with 2 x 120mm corsair SP fans blowing direct onto the GPUs from front, one additional intake in front - a cheap garbage fan, two x 140mm corsair AF fans on the top for exhaust, and one additional exhause case fan out the back.

Thanks in advance

To make deduction (answers) more accurate, tell us what m/b you use , so to determine where that 3 slot card would fit best.

I have this one: http://www.asus.com/Motherboards/SABERTOOTH_990FX_R20/

Sabertooth 990FX R.20

Resolved. I really only had one option due to various configuration elements:

XFX
Asus
PC

Thanks.
