    Hello Hilbert, Unwinder, and friends,

    I wanted to report a potential bug in 2.2.0 Beta 15 with the 301.10 drivers on a GTX 680. My environment is x64 win7.

    I spent a lot of time testing out the features available in 2.2.0 Beta 15. Specifically, the user defined fan curve is overridden by the driver occasionally.

    I observed the Temp, Vcore, and Core clocks stay static, while the fan speed dropped from 75% down 10-20% then climbed back up after a moment. No changes in temp/vcore/clocks occurred during this time.

    ^^For this reason, I wanted to report this potential bug. I will try "Force fan speed update" at the default period to see if that helps.

    I also have a hysteresis of 5c set if that helps to locate the issue.
