My older Geforce 560 GTX would do the same on post or in the bios until windows booted up and loaded the driver then you could hear the fan quite down. On shutdown you would hear the fan ramp up to fixed speed until the power supply switched off.
Built in protection within the graphic card bios for when no operating system/driver is running to control fan speed.

Opening the case and LOOK INSIDE generally helps. How do you expect to solve a problem if you don't know the culprit?
If you want to explore the graphics driver as a possibility, you can easily go to Nvidia's site and install the previous driver. If the fan problem goes away, the answer is yes.
