    I have been having an issue for the past few days where my CPU Fan spins mostly at 2800 RPM then will sometimes drop as low as 0 for a couple seconds then back up to 2800.. Immediately when I turn on my PC it spins to 2800 RPM..I have a Scythe Ninja 3 fan and Asus P8Z68-V Pro motherboard.. Could this be anything software related or is the fan about to die?

    You should take your temps, fan speeds and voltages from Asus Suit II

    This can be found on the support page for your motherboard
    http://www.asus.com/Motherboards/P8Z68V_PRO/HelpDesk_Download/

    If you install the full Asus Suit II package you can also use the Fan Xpert utility to set what speed you want your fans running at which temperature.

    Yes I did that and the temps are normal its the fact the fan doesnt seem to take into consideration what the temps are it just sits at 2800 RPM. I also noticed that Fan Xpert registers my fan speed at ~2800 RPM at 20%-100% Fan Power. See image.
