Gainward PowerPack! CoolFX Ultra/2600 TV-DVI-DVI @ TrustedReviews
To scale these heights, the CoolFX doesn?t bother with your run-of-the-mill air cooling but instead uses water cooling to keep excessive heat under control. Water cooling brings two key advantages ? first, it keeps the card cooler than any conventional fan, enabling it to be run at much higher frequencies. It?s also much quieter, so you can get the benefit of higher clocks without any of the noise intrusion of a high-rpm fan.
