Ok, I have a GTX 560 ti, which I currently don't use due to a major overheating problem, and have finally got round to trying to do something with it. The problem began completely randomly. The problem is that, according to MSI afterburner, it was running at 80oC idle, and up to 90oC under stress, with fan speed making no difference to the temp, although I hear it speeding up. Any ideas of what to do? My rig is as follows: AMD FX-4100 3.4GHZ Quad Core, AMD Radeon 6670, and 8GB RAM.
