HEXUS posted a review on the Sapphire TOXIC Radeon X1900 XTX

The reference cooler ATI equipped their Radeon X1800 XT and Radeon X1900 XT/XTX with is effective, there's no doubting that. Cools the chip well, actively cools the memory; job is indeed a good'un, as they say. Shame it's the sonic equivalent of a punch in the face, then.
