I Bought two 5770 Gigabyte graphics cards, with a Gig of RAM each to run in crossfire, but when playing Crysis with the 1.2 patch. I noticed that the top card was heating up to 100 C plus and the bottom card was hitting 80 to 90 C. What would be the best low profile card cooler I could put on them to take care of the problem? I need low profile coolers because the PCI-E slots on my motherboard are pretty close together and the standard cooler supplied only just allows enough room for the bottom card.
