So I purchased the Asus EAH5870 v2 and am currently running it at 951/5004. I notice during furmark the temp gets up to 81c. During gaming it gets to around 72c. About 40c idle. These temps seems a little high, especially since I have high a high air flow case. Also, I'm having difficulty getting the card to be stable after 951mhz, even if I increase the voltage. I'm using the Asus smartdoctor for overclocking and overvoltage. Any suggestions?
