Yesterday VR Zone wrote that NVIDIA's GeForce GTX 580 would have a slightly lower TDP than the GeForce GTX 480, while today a report KitGuru claims that the card may use 25W more than the GeForce GTX 480. Additionally, the site also claims that watercooled units will ship shortly after launch as the GeForce GTX 580 has a similar design as its predecessor.
Our sources in the Far East have indicated that the new chip will draw at least 35w more than the older Fermi. Naturally, you would expect that with an additional 32 processing units needing power. Running at full pelt with FurMark is likely to generate a significant amount of heat. The question becomes. what is the best way to deal with that heat?
