Likewise, I have not upgraded my BIOS and am still on A09. In my case, the fan cycles between high and low (a few seconds between cycles), regardless of what kind of system activity is going on. I'll have to verify temps, but this occurs the instant the driver kicks when X starts. I don't think the gpu would even have had time to heat up much above ambient by then but i'll double check.
