Summary: The cooling performance of this card is out of this world. The fan is practically inaudible with the card in the test rig only a few feet away from me. The temperatures were very low as we've seen and the driver controlling the fan speed does a great job. The Vapor-X cooling has a great benefit for all you overclockers out there.
Cooler temperatures usually equate to higher potential overclocks. Again, this rings true with the Sapphire HD 4870 Vapor-X Edition.
Pros: - Vapor-X Cooling, - Native HDMI, - 800 stream processors + 230GB/sec o memory bandwidth, - Black Diamond - Sapphire choke offers 10% cooler and 25% more power efficiancy than normal choke
Cons: - Hot competition from the many, many other 4870 cards out there., - Price.
