Best cooling for 6990 Tags: Radeon Cooling Water Cooling Graphics Last response: October 30, 2011 2:36 PM in Graphics & Displays Share pnico October 30, 2011 2:27:28 PM Hi, What is the best cooling for 2 6990s? Is it liquid cooling? Problem may be that they are too close together however. The case was an original alienware case a few years old, but has been since upgraded from a 4870x2 to the 6990, 980x, 12 gig ddr ram, asus p6t deluxe v2 board. Seems that when I enable both cards, the system reboots itself, but runs fine with the one. The only thing I can think of is that it is getting too hot and needs to stop. That is the only time its rebooted. Running windows 7. thanks More about : cooling 6990 hellfire24 October 30, 2011 2:36:46 PM yes.it is liquid cooling.6990 is a powerhouse but it requires extreme cooling to run cool under load.and for crossfire,your heat gets doubled.i would suggest liquid cooling. these things look pretty good to me- http://www.frozencpu.com/products/12814/ex-blc-890/EK_R...
