Hi all, I have two 580s in SLI running on an i7 920 with a mild 3.2 overclock. The case is a Corsair Obsidian with the three stock fans and an additional four. Typical temps under load are 29C for the SSD, 30C for the HDD and 50C for the CPU. But the GTX 580s run 89C and 88C respectively after extended sessions (two to three hours) of demanding games like Crysis Warhead. Is this normal for an air-cooled case? Should I be worried? The GPUs are running at stock speeds.
