2x 6970 with Accelero XTREME Plus II? - Page 2

post #11 of 12
For Gigabyte Ga-990FXA-UD7, there are only 2 possible positions for 6970 with AXP.

Pic 1 (top card in PCIEX16_1 and bottom card in PCIEX16_2)
Pros:-
a) 1 empty slot space below the top card
b) bottom card has ample space underneath (inside a 9-slot HAF-X)
c) both slots operate at x16 and zero performance loss

Cons:-
a) no place for sound card. If a sound card is installed between the 2 6970s, then the top card will suffocate
b) a small chance of having physical conflict between bottom card's AXP with mobo's cable headers along bottom edge

Pic 2 (top card in PCIEX16_1 and bottom card in PCIEX8_2)
Pros:-
a) 2 empty slot space below the top card which will breathe easier
b) a sound card can be installed (preferably in the PCI slot)

Cons:-
a) lower card will operate at x8 and will suffer about 2% performance loss
b) lower card will get closer to the PSU below and will not breathe as easy as Pic 1
c) a small chance of problem with using these 2 slots to do CF
d) a higher chance of having physical conflict between bottom card's AXP with the cable headers along bottom edge of motherboard.

So I guess it comes down to how much I want to OC my video cards vs having a sound card. I have never had anything besides onboard sound, so I guess I wouldn't be missing it that much.

I take it there is really no other solution to cooling besides water? Oh and even with the 200mm putting fresh air into there, that seems like it would still be too tight a fit :/.

Edit: Besides the noise, would turning the stock fans up be enough to cool them with some overclocking done?
