3 X 7950 Setup with IceQ X2 Cards

[bzh]

Ordering 7950s, but I wanted to know if anyone has any info or benchmarks (coin related) to this specific brand/model. HIS IceQ X2 7950 boost seems the best balance of heat/noise/power draw for a card with higher stock clocks.

Already have these parts:
PSU : SeaSonic X-SERIES X-1050 1050W
Mobo : GIGABYTE GA-X79-UP4 LGA 2011 Intel X79 SATA 6Gb/s USB 3.0 ATX Intel Motherboard
Case: Corsair Graphite Series 600T with stock fans
Additional cooling:  CORSAIR H55 for CPU
Additional cooling: Vantec Spectrum Fan Card (not sure where i should place this, above, between, beneath the cards?)

Not really wanting opinion on the rest of my build but posted as it may be relevant to getting an answer. Thanks in advance!

Heard that it doesnt have voltage control... Which means it's gonna be pretty power hungry as you cant undervolt it.
