Yep the GPU runs off the single rad. CPU and NB off of the Dual. During a run of Vantage I get temps of 30-32 for one GPU and the other runs 40-42. Not sure why the big difference but both run cool enough for me to not worry about it. The card is also OC'd to 700/1000. The CPU which is a [email protected] with 1.47v gets into the Mid to high 50's running prime.
