When the HIS HD4850 IceQ 4 TurboX finally arrived, I knew I was in for a treat. It comes overclocked from the factory by a hefty margin without increasing the heat on the card or the noise. Compared to my Sapphire Toxic and 8800GT OC2, this card is whisper quiet. I wasn't even sure if the fan was working properly because it was so quiet. It sounds cliche, but with every aftermarket cooler or stock cooler I've tried, they always end up being louder than I thought they would be. Not with the IceQ 4. HIS engineers have done a fine job at perfecting this cooler.
