    I'm seeing higher temperatures on my GPU under Lion, what gives?

    I'm running 10 to 15 degrees hotter across the board, GPU, Diode and the Heatsink since upgrading to Lion. :confused:


    Tried to install the graphics updates Apple released today and it says not supported on my system...

    A lot of us are getting that. That's what caused all of my freezes. Put a fan facing on the back of my iMac and cranked up the fans with smsFanControl and i rarely freeze/crash now. It's definitely an issue with Lion. Never froze on Snow Leopard. Never.
