The current HIS IceQ doesn't have the issue my XFX card did, which is what I was referencing above.
My temps on the bottom card are around 65*c and the top is about 75*c when running Heaven/Valley for 30 minutes @ 1100mhz on the core. I haven't messed with the voltage. So, I think it's using the boost voltage of 1.25v. I've left the memory clocks stock for now.
I've found that removing the plates on the empty slots (between the cards) helps with heat dissipation, but every case is different. The Arc Midi in my sig has pretty good cooling throughout.
