Hi, I just made a new i7 build and my crossfire 4890's are getting super hot. On idle I saw one at 79 C and the other at 70 C. I have a lain li p50, and it's only today I noticed these super high temps! Usually when I game they only get to about 69 C on stock. Is there anything I can do to remedy this situation besides having to water cool. i have an Asus Rampage 2 motherboard so the two cards are really sandwiched together. My case is an enclosed space if that helps, though I figured that wouldn't be much of a problem. Right now I have both their fans at 100% but it makes more noise than my Dyson. Any help would be appreciated!
