    I believe it's normal when (re) booting your MP, the fan(s) of the GPU spins to a max and then turn to idle mode. With the 8800GT it's just the same.

    I have the same issue, i.e. loud GPU fan noise and high PCIe-RPM directly after boot-up. While it does quiet down after a while it helps to briefly tax the GPU (i.e. with some GPU benchmark tool such as OpenGL viewer, furmark) after which the fans come down very quickly. I think this has been reported before.

    I forgot to ask if you had a visual check on the GPU and first of all, is it DUST FREE?

    Try slot 2.

    If that doesn't fix it, you'll either have to use your sleep trick or tax the GPU trick.

    Same Problem since 10.9.2. (PCI-Fan spinnig high)

    Macs Fan Control help me to bring down the PCI-Fan and run it at normal speed of 900 RPM.

    ----------

    CUDA-Z works also and you must only start the Programm. But you must have the CUDA Driver installed.

    Macs Fan Control was a better choice for me.
