NEW Diamond 6990 - $450 shippedJust picked this up locally, took it out of the static bag and tested to make sure it posted. Mint as could be!
Powercolor 6990 with Artic cooler - $400 shipped obo Picked this up a week ago and while its a beast, I have decided to sit summer out and wait for 89xx series. Includes the Artic dual fan 6990 cooler and stock heatsink.
My findings over the past week running 24/7
-This artic cooler keeps each gpu well under 68c @ 900 core, 775 mem, 70c vrm, 1.12v (switch in low voltage setting).
-The artic 2mm thermal pads for the vrm's were terrible so I replaced with two layers of 1mm pads (not optimal, but all I had). This dropped the vrm temp from ~82c > 75c. I added a small fan on top as see in the pic and this further drops the vrm's typically under 70c. I would suggest replacing with quality 1.5-2mm pads which will further drop the vrm's well under 70c with good airflow.
-They will run 950 core stable at the low voltage setting however the vrm's would sit around ~78c and I did not want to run this 24/7 until I could replace the vrm thermal pads with proper 1.5-2mm as mentioned above.
