Re: Official Radeon HD 6990 reviews
Some reviews are getting better results than others. Some reviews are putting it below the 480 GTX in noise and power consumption, even below the 580 GTX sometimes. Rumor has it, they are using phase change thermal paste that needs to be cycled and cooked in first, and removing the heatsink to take the card apart(many reviewers do) requires reapplying the paste, if not done correctly it can cause improper heat transfer.
Might explain the mixed heat/sound results.
