Quick update for those who care:
Ninja 3 Cooler without any fan on it has i7 980x running at 90C per core. With 120mm fan added to the coler the 980X runs at 74C. Curently still running only 1 x 6990, because I still did ton recieve my aux PSU. The total systep power load on my APC UPS is 580watts. this includes 980X plus 1 HD6990 card and 12 GB of RAM in Rampage III formula mobo.
I am using antec 1200 case with top and back fans on; on high.
Potential problems with this set up:
1. The fan on Ninja3 cooler is only about an inch away from 6990. So air intake is effected but it still works good for air cooling. I7 980X is at 74 degrees C under full load. Ninja 3 cooler will block one of DDR3 slots on mobo, unless the ram module in that slot has to hear sink ontop of its heat spreader.
2. The location of the fan on 6990 is too close to the back of the case and can be blocked by a card sitting in the next slot over. 6990s have rubber feet on pcb to keep them separated when plugged into slots near eachother, but you may have problems if you have a different card in the slot next to 9660 which has no rubber feet.
3. Exhaust of hot air into the case is not a big problem due to size of the cards. The air exhaust into the case is so close to the front of the case that reversing the direction of fan on forward side of the case sucks that hot air out of the case.
4. Dont expect to have HDs or anything else mounted in case bays whch are next to the cards...
6990 under a full load is not as loud as 4870x2 was, but close.
I'll keep updating as i learn more... Every onle already has the benchmarks posted online, so i will try to concentrate mostly on mechanical aspects of the setup...
RAM heatsinks dont really do much of anything, Sounds like you need a bigger motherboard.
