I have a GTX 590 that gets too hot while playing newer games. When I disable SLI to use only one of the 2 GPU's on board it actually gets worse than when SLI is on and the load is divided. I'm interested in undervolting the card and lower the clocks to see if I can make the temperatures a little better and still run games alright. First off, is this a bad idea? Second, if not, how can I try it? Are there any dangers to the card trying this, or is it similar to playing around with a CPU where if the clocks are too high for the voltage it'll just crash and try another setting?
