A quote from the article:
>> Sapphire HD 4890 Toxic / Vapor-X Review
Sapphire's HD 4890 Toxic uses their exclusive Vapor-X cooling technology. This results in a card that delivers considerably more performance than the HD 4890 reference, yet does so without any excess noise. Actually the Sapphire HD 4890 Toxic is the quietest HD 4890 we ever had in our hands.
