Radeon HD 7990 Review -- Part 2
#3
yeah, it's six 120mm fans in 3+3 configuration. they actually push less air than the previous revision which had three 120mm fans, because the previous revision allowed you to disable fan control in the bios to run the chassis fans at 100% full time. this new revision does not give you that option, which is rather disappointing. but they still get the job done.

yes, 4x 7990 uses quite a bit less power compared to 8x 7970: 1500W as opposed to 2000-2200W.

there's also a third advantage as well, and that's if you're going infiniband, you can only put 7x 7970 in each system because you have to leave a slot free for the HCA. whereas with 4x 7990 you can have infiniband plus the full 8 GPUs.

this is definitely the way forward for us.
