Help: NVidia Quadro K600 GPU power management

[geteng666]

Hi,
I have successfully installed OS X 10.9.4 on my thinkstation.
The CPU is Xeon E3 1240V3,
Graphics is NVidia Quadro K600.
I installed the NVidia web driver, and it works good. But the only problem is the GPU keeps working at full speed, and the GPU fan maintains at a high spinning rate, which is a bit noisy.

I'm wondering anyone can give me a direction to start fixing the GPU power management?
I'm using unibeast, and the boot flags are:
<key>EthernetBuiltIn</key>
<string>Yes</string>
<key>DropSSDT</key>
<string>Yes</string>
<key>Graphics Mode</key>
<string>"1920x1080x32"</string>
<key>GraphicsEnabler</key>
<string>No</string>
<key>IGPEnabler</key>
<string>Yes</string>
<key>Kernel</key>
<string>mach_kernel</string>
<key>Kernel Flags</key>
<string> nvda_drv=1</string>
<key>Legacy Logo</key>
<string>Yes</string>
<key>Timeout</key>
<string>2</string>
<key>UseKernelCache</key>
<string>Yes</string>

Thanks
